Total2022
All inputs and outputs are discrete and can be
active simultaneously.
The ADAT optical ports provide 4 channels of I/O
at 88.2 or 96kHz. They can also be independently
configured as stereo TOSLink SPDIF at any
supported sample rate (up to 96kHz).
All digital I/O is disabled for 192kHz operation.
The headphone outputs can operate as an
independent output pair, or they can mirror any
other Traveler output pair, such as the main outs.
Mic/instrument inputs
The four mic/instrument inputs are equipped with
preamps and Neutrik™ “combo” XLR/TRS jacks,
which accept low-Z XLR microphone inputs or
high-Z quarter-inch guitar/instruments inputs.
The total gain range for these preamps, including
the 20dB pad, is 73dB, allowing you to connect
anything from guitars and microphones to +4dB
or –10dB line level signals. Preamp gain and pad
can be controlled from the front panel digital
rotary encoders/switches or the included CueMix
Console™ software.
Analog
All four quarter-inch analog inputs are equipped
with 24-bit 192kHz, 64x oversampling A/D
converters. All eight analog outputs have 24-bit
128x oversampling D/A converters. All audio is
carried to the computer in a 24-bit data stream. All
eight analog outputs and four quarter-inch inputs
are on balanced TRS +4dB quarter-inch jacks. All
of these jacks can also accept unbalanced plugs.
The quarter-inch analog inputs can be switched in
pairs between a +4 and -10dB reference level. An
additional 6dB of software boost can be applied to
each channel individually via the CueMix Console
software application or via the front panel LCD
display.
Optical
The Traveler optical jacks support two digital audio
formats: ADAT and S/PDIF. The ADAT optical
format provides eight channels of 24-bit digital
audio at either 44.1 or 48 kHz, and four channels at
88.2 or 96kHz. The optical S/PDIF format (often
referred to as
TOSLink
), supplies stereo S/PDIF
input or output. The optical jacks are disabled at
the 4x sample rates (176.4 and 192kHz).
AES/EBU
The Traveler rear panel provides a standard AES/
EBU digital input and output that supports digital
I/O at 44.1, 48, 88.2 and 96 kHz. The AES/EBU
jacks are disabled at the 4x sample rates (176.4 and
192kHz).
S/PDIF
The Traveler rear panel provides S/PDIF input and
output in two different formats: RCA “coax” and
optic al “ TOSLi nk”. The RCA jacks are dedicated to
the S/PDIF format. The TOSLink jacks can be used
either for either TOSLink or ADAT optical. The
optical input /output jacks can operate independently. For example, the optical input can be set to

TOSLink while the optical output is set to ADAT.
The RCA and optical S/PDIF jacks are disabled at
the 4x sample rates (176.4 and 192kHz).
On-board SMPTE synchronization
The Traveler can resolve directly to SMPTE time
code via any analog input, without a separate
synchronizer. The Traveler can also generate time
code via any analog o utpu t. Th e Trave ler prov ide s a
DSP-driven phase-lock engine with sophisticated
filtering that provides fast lockup times and subframe accuracy. Direct time code synchronization
is supported by AudioDesk and Digital Performer
on Mac OS X.
The included FireWire SM PTE Console™ software
provides a complete set of tools to generate SMPTE
for striping, regenerating or slaving other devices
to the computer.
ADAT sync: sample-accurate synchronization
The Traveler’s standard 9-pin ADAT SYNC IN
connector provides sample-accurate synchronization with all Alesis ADAT tape decks connected
to the system—or any device that supports the
ADAT sync format. For example, if you digitally
transfer a single track of material from an ADAT
via light pipe into audio workstation software on
the computer, and then transfer the track back to
the ADAT, it will be recorded exactly at its original
location, down to the sample.
Word clock
The Traveler provides standard word clock that can
slave to any supported sample rate. In addition,
word clock can resolve to and generate “high” and
“low” sample rates. For example, if the Traveler
global sample rate is set to 96 kHz, the word clock
input can resolve to a “low” rate of 48 kHz.
Similarly, when the Traveler is operating at 96 kHz,
the MOTU FireWire Audio Console lets you
choose a word clock output rate of 48 kHz.
1394 FireWire
The two 1394 FireWire jacks accept a standard
IEEE 1394 FireWire cable to connect the Traveler to
a FireWire-equipped Macintosh or Windows
computer. The second jack can be used to daisy
chain multiple interfaces — up to four MOTU
FireWire interfaces — on a single FireWire bus. It
can also be used to connect other FireWire devices
without the need for a FireWire hub. The Traveler
has the ability to power itself from its FireWire
connection to the computer.
THE TRAVELER FRONT PANEL
Phantom power
Individual 48V phantom power can be enabled for
each preamp with the four front panel switches.
Digital Precision Trim™ rotary encoders
The four Digital Precision Trim™ detented rotary
encoders provide preamp gain adjustment and also
serve as 20dB pad switches when pushed. When
you turn these trim knobs, input gain can be
adjusted in 1dB increments, and the LCD display
provides active numeric feedback as the
adjustment is made.
Headphone output and main volume control
The Traveler front panel includes a quarter-inch
stereo headphone output jack and volume knob.
The volume knob also controls the rear-panel m ain
outs. Push the knob to toggle between them. The
LCD display provides feedback.
CueMix™ DSP no-latency on-board mixing
The CueMix DSP section of the front-panel
provides access to the Traveler’s on-board mixing
features, as well as global system settings. Together,
these features provide complete stand-alone
operation, without a computer. The Traveler can
mix all inputs to any output pair, and up to four
such mixes can be independently programmed
and simultaneously operated.
ABOUT THE TRAVELER

Page 12
Backlit LCD display
Any Traveler setting can be accessed directly from
the front panel using the six rotary encoders and
the 2x16 backlit LCD display. CueMix DSP settings
such as input gain, panning, +4/-10 input level,
6dB boost, stereo pair grouping, mix output
assignment and others are quickly accessed, clearly
marked and easy to adjust. Sixteen presets can be
created, saved, recalled and duplicated.
Metering section
The front panel of the Traveler displays several
banks of input metering and output activity LEDs.
The round analog, SPDIF and AES/EBU output
activity LEDs, as well as the ADAT optical in/out
activity LEDs, display signal presence. The
threshold for these lights is approximately -42 dB.
The four-segment input meters provide dedicated
multi-segment metering for their respective inputs.
Clock
The
lights indicate the global sample rate (as
chosen in the MOTU FireWire Audio Console
software). The LOCK and TACH LEDs provide
feedback for the Traveler’s on-board SMPTE
synchronization features.
TRAVELER SIDE PANEL
MIDI I/O
The Traveler’s standard MIDI IN and MIDI OUT
jacks supply 16 channels of MIDI I/O to and from
the computer via the Traveler’s FireWire
connection. Timing accuracy can be sampleaccurate with host software that supports it.
Bus power
The Traveler can draw power from three possible
sources:
1. the computer (via the FireWire cable connection
between the Traveler and the computer)
2. an external battery pack (purchased separately)
3. a DC power supply
If you are using FireWire bus power only, then the
Bus Power switch needs to be turned on. However,
if you are using battery or DC power, and you do
not wish to draw power from the computer (to
conserve your laptop battery, for example), you can
disable bus power by moving the Bus Power switch
Off
to the
position.
Battery power
The 4-pin XLR battery power jack allows you to
connect a standard DC battery pack for extended
remote recording. The battery pack must supply a
minimum of 10-18 volts and 12 watts. For further
details, contact your preferred supplier of
professional audio/video equipment.
Power supply
If you do not want the Traveler to draw power from
the computer, and AC power is available, you can
power the Traveler from any standard 10-18V,
12 watt DC power supply with any polarity (tip
positive or negative).
16-BIT AND 24-BIT RECORDING
The Traveler system handles all data with a 24-bit
signal path, regardless of the I/O format. You can
record and play back 16-bit or 24-bit audio files at
any supported sample rate via any of the Traveler’s
analog or digital inputs and outputs. 24-bit audio
files can be recorded with any compatible host
application that supports 24-bit recording.
AUDIODESK
AudioDesk is a full-featured, 24-bit audio
workstation software package included with the
Trave l er sy st em (for Macintosh only). AudioDesk
provides multi-channel waveform editing,
automated virtual mixing, graphic editing of ramp
automation, real-time effects plug-ins with 32-bit
floating point processing, crossfades, support for
many third-party audio plug-ins, background
processing of file-based operations, sampleaccurate editing and placement of audio, and more.

DIGITAL PERFORMER
The Traveler system is fully integrated with
MOTU’s award-winning Digital Performer audio
sequencer software package.
OTHER HOST AUDIO SOFTWARE
The Traveler system includes a standard Mac OS X
Core Audio driver for multichannel I/O with any
audio application that supports Core Audio.
A COMPUTER-BASED SYSTEM
Regardless of what software you use with the
Trave l er, t he ho st co m p uter determines the
number of tracks the software can record and play
simultaneously, as well as the amount of real-time
effects processing you can apply to your mix. A
faster computer with more RAM and faster hard
drives will allow more simultaneous tracks and
real-time effects than a slower computer with less
RAM and slower hard drives. Today’s fastest
computers can typically play as many as 72 tracks
or more.

IMPORTANT NOTE BEFORE YOU BEGIN!
Before you begin installing the Traveler (or any
bus-powered device), take these important
precautionar y measures to avoid damaging the
sensitive electrical components in your computer,
the Traveler or other devices being connected:
■
Tur n o ff th e co mp u te r.
■
Tur n o ff the Tra v el er ’s front panel power switch.
■
Tur n o ff th e power of any other devices.
■
Tou ch t h e m e ta l casing of the Traveler to
discharge any static electricity that you may be
carrying just before the installation.
After you have made all of the necessary
connections, as described in this chapter, turn on
the devices in this sequence:
1. Turn on the computer.
2. Turn on the Traveler.
3. Turn on other devices connected to the Traveler.
Plug one end of the Traveler FireWire cable
(included) into the FireWire socket on the
computer as shown below in Figure 3-1.
Yo u can connect the Traveler to an 800Mbit
☛
“FireWire B” port using a 9-pin to 6-pin FireWire B
cable (not shown). However, the Traveler will still
operate at its specified 400Mbit (FireWire A) data
rate.
CONNECT AUDIO INPUTS AND OUTPUTS
The Traveler audio interface has the following
audio input and output connectors:
8 balanced, +4 dB quarter-inch analog outputs
■
■
4 balanced +4/-10 dB quarter-inch analog
inputs
4 Neutrik™ XLR/quarter-inch analog inputs
■
with preamps
1 pair of RCA S/PDIF in and out
■
■ 1 pair of AES/EBU in and out
3
Plug the other end of the FireWire cable into the
Trave l er I/O as shown below in Figure 3-1.
■ 1 pair of optical in/out switchable between
ADAT (“Lightpipe”) or optical S/PDIF (TOSLink)
Here are a few things you should keep in mind as
you are making these connections to other devices.
Mic/guitar/instrument inputs
Connect a microphone, guitar or other similar
instrument to the front-panel inputs, as
recommended in the table below. If your
microphone requires phantom power, move the
48V phantom power switch on the front panel to
the right (enabled). Use the trim knobs on the front
panel to adjust the input level as needed for each
input. The LCD provides feedback for the current
trim setting. The Traveler’s input trims are digital
controlled, so they allow you to make fine-tuned
adjustments in approximately 1dB increments. Use
the four input level meters on the front panel
(labeled ANALOG 1-4) to calibrate the level. These
meters register for both the XLR and TRS input.

To t og gle th e pa d, push the input’s trim knob. The
LCD provides feedback for the current pad setting.
The pad settings above are recommended initial
settings. Use the front-panel trim knobs to adjust
input levels, and use the Traveler’s front-panel
4-segment meters to adjust the gain accordingly. If
necessary, after adjusting the trim, you can enable
or disable the pad as needed, depending on actual
signal levels.
Quarter-inch analog
The quarter-inch analog inputs (5-8) and outputs
(1-8) are balanced TRS connectors that can also
accept an unbalanced plug. The outputs are all
referenced to +4dBu. The inputs can be manually
set to either +4 or -10dBu. Use the front panel
controls to adjust the reference level (+4/-10) as
needed for each input (or input pair) as follows:
1 Tur n t h e PA RAM kn ob until you see the “4/10”
setting displayed in the LCD, as shown below.
If turning the PARAM knob doesn’t do anything,
press the SETUP knob once, and then turn it.
S/PDIF “TOSLink” device. Just make the
connections as needed and then you’ll set the
format later in the MOTU FireWire Audio Console.
Input and output are independent. For example,
you could connect ADAT optical input from your
digital mixer and connect TOSLink optical output
to your DAT deck.
The optical S/PDIF jacks are disabled at the 4x
sample rates (176.4 and 192kHz).
Analog outputs 1-2 can serve as main outs
Analog outputs 1-2 can serve as main outputs. The
main out volume is controlled by the volume knob
on the front panel. Push the knob to toggle
between phone and main out volume control. In a
standard studio configuration, the main outs are
intended for a pair of studio monitors, but they can
also be used as regular outputs for any purpose.
CONNECT MIDI GEAR
Connect your MIDI device’s MIDI IN jack to the
Trave l er ’s M ID I O UT jack (Connection A below).
Conversely, connect the MIDI device’s MIDI OUT
jack to the Traveler’s MIDI IN jack (Connection B).

send data, such as a sound module, only need
Connection A. Make both connections for any
device that needs to both send and receive MIDI
data.
Connecting additional gear with MIDI THRUs
If you need to connect several pieces of MIDI gear,
run a MIDI cable from the MIDI THRU of a device
already connected to the Traveler to the MIDI IN
on the additional device as shown below in
Figure 3-4. The two devices then share the
Trave l er ’s M ID I O UT port. This means that they
share the same set of 16 MIDI channels, too, so try
to do this with devices that receive on only one
MIDI channel (such as effects modules) so their
receive channels don’t conflict with one another.

When ope rating und er bus power, daisy-chaining
is not recommended
The Traveler can be daisy-chained with other
FireWire devices from a single FireWire
connection to the computer. However, if the
Trave l er is operating under bus power, this is not
recommended. If you need to daisy chain the
Trave l er wit h ot he r d ev ices on the same FireWire
bus, power the Traveler with a DC power supply
(or battery), and turn off the Bus Power switch on
the side panel. The other devices on the chain
should also have their own power supply. In
general, bus-powered FireWire devices should not
be daisy-chained.
FireWire adapter products must be powered
If you are using a FireWire adapter (a third-party
product that supplies one or more FireWire ports
to your computer), it must have direct access to a
power supply:
■ PCI FireWire cards — If you plan to connect the
Trave l er to a P CI card and run the Traveler under
bus power, the PCI card must have a direct
connection to the power supply harness inside
your computer. This is the same power supply
harness to which you connect internal hard drives,
CD/DVD drives, etc.
■ PCMCIA slot adapters — If you plan to connect
the Traveler to a PC card FireWire adapter
(inserted in the PC card slot in your laptop), it
must provide a 6-pin connection and it must also
have its own power supply. Most commonly, these
types of products have a DC power adapter that
plugs into an AC wall outlet. As you can see,
however, this situation does not allow for remote
battery operation, as the PC card adapter requires
AC.
Examples of bus- powered operation
Here are a few typical examples of bus-powered
Tr a v e l e r operation:
Bus power from a desktop computer
Yo ur de s k t op c om puter is running off of its usual
AC power connection, and the Traveler draws
power from the FireWire cable connected to the
computer. There are no limits to running time.
Bus power from an AC-powered laptop
This scenario is identical to the desktop situation
described above: the laptop is powered by AC, the
Trave l er is po we re d via t he FireWire bus and there
are no limits to running time.
Bus power from a battery-powered laptop
The laptop is being powered by its own battery, and
the Traveler is being powered by its FireWire
connection to the computer. So the laptop battery
is supplying power to both the laptop and the
Trave l er. T hi s i s the mo st compact and portable
operat ing scenario. Running time is determined by
the capacity of the laptop battery. For extended
recording sessions, bring extra, fully charged
laptop batteries.
Powering the Traveler from a battery pack
The 4-pin XLR battery jack on the Traveler side
panel allows you to connect a standard DC battery
pack, which is ideal for extended remote recording.
These products can provide multiple hours of
operation, depending on their capacity. The
battery pack should supply 10-18 volts and 12
watts. A typical application would employ a 12 volt
battery, therefore requiring 1 amp. In this scenario,
a 1 amp-hour battery will power the unit for
1 hour. A 10 amp-hour battery will power the unit
for 10 hours. Follow the manufacturer’s recommendations for battery discharge for proper
battery maintenance. For further details, contact
your p referred supplier of professional audio/video
equipment.
INSTALLING THE TRAVELER HARDWARE
21
Page 22
DC power supply
If you do not want the Traveler to draw power from
the computer, and AC power is available, you can
power the Traveler from any standard 8-18 volt,
12 watt DC power supply with any polarity (tip
positive or negative), and amperage as shown
below. To prevent the Traveler from drawing power
from the computer, turn off the Bus Power switch.
VoltageAmperage
9 volts1.33 amps
12 volts1 amp
18 volts0.66 amps
The Bus Power Enable/Disable switch
The Bus Power Enable/Disable switch on the side
panel of the Traveler lets you control whether or
not the Traveler draws power from the computer
via FireWire.
For example, when battery or DC power supply
options are not being used, and FireWire is the
only available power source, t urn on the Bus Power
switch.
If you are powering the Traveler via battery or DC
power supply, and you do not want it to draw
power from the computer (perhaps because it is a
laptop running under its own battery, and you
don’t want the Traveler to run down the laptop’s
battery unnecessarily), turn off the Bus Power
switch.

A TYPICAL TRAVELER SETUP (NO MIXER)
Here is a typical Tr a v e l e r studio setup. This rig can
be operated without an external mixer. All mixing
and processing can be done in the computer with
audio software. During recording, you can use the
Tr av el er ’s Cu eM ix ™ DSP no-latency monitoring to
listen to what you are recording via the main outs,
headphone outs, or any other output pair. You can
control monitoring either from the front panel or
from the included CueMix Console software.

USING THE TRAVELER WITH A MIXER
While there are many ways to use the Traveler with
an external mixer, typically the Traveler serves as a
mult i-cha nnel “p ipeli ne” between the mixer and
the computer. If your mixer is analog, connect the
analog section of the Traveler to your mixer. If your
mixer is digital, and it has ADAT optical I/O, you
can connect them optically as shown below in
Figure 3-8. The Traveler’s available analog, SPDIF
Mac
FireWire
and AES/EBU inputs and outputs can serve as an
extension to the mixer I/O, but then you will
probably find yourself mixing in two places: the
mixer and the computer. A word of advice: if you
would like to use the Traveler with an external
mixer, use the mixer for mixing. Trying to mix
large multitrack projects in two places can become
very cumbersome very quickly.

MAKING SYNC CONNECTIONS
If you connect devices digitally to the Traveler, or if
you need to synchronize the Traveler with an
outside time reference such as SMPTE time code,
you must pay careful attention to the synchronization connections and clock source issues
discussed in the next few sections.
Do you need to synchronize the Traveler?
If you will be u sin g on ly the Tra vel er’s a nalo g in put s
and outputs (and none of its digital I/O), and you
have no plans to synchronize your Traveler system
to SMPTE time code, you don’t need to make any
sync connections. You can skip this section and
proceed to chapter 4, “Installing the Traveler Mac
OS X Software” (page 39). After you install the
Trave le r s of twa r e, you’l l open the MOTU FireWire
Audio Console and set the Clock Source setting to Inter nal as shown below. For details, see chapter 5,
“MOTU FireWire Audio Console” (page 43).
Figure 3-9: You can run the Traveler under its own internal clock when
it has no digital audio connections and you are not synchronizing the
Traveler system to an external time reference such as SMPTE.
Situations that require synchronization
There are three general cases in which you will
need to resolve the Traveler with other devices:
■ Synchronizing the Traveler with other digital
audio devices so that their digital audio clocks are
phase-locked (as shown in Figure 3-10)
■ Slaving the Traveler system to SMPTE time code
from a video deck, analog multi-track, etc.
■ Both of the above
Synchronization is critical for clean digital I/O
Synchronization is critical in any audio system, but
it is especially important when you are transferring
audio between digital audio devices. You r su ccess
in using the Traveler’s digital I/O features depends
almost entirely on proper synchronization. The
following sections guide you through several
recommended scenarios.
Be sure to choose a digital audio clock master
When you transfer digital audio between two
devices, their audio clocks must be in phase with
one another — or phase-locked. Otherwise, you’ll
hear clicks, pops, and distortion in the audio — or
perhaps no audio at all.
Not phase-lockedPhase-locked
Device A
Device B
Figure 3-10: When transferring audio, two devices must have phaselocked audio clocks to prevent clicks, pops or other artifacts.
There are two ways to achieve phase lock: slave one
device to the other, or slave both devices to a third
master clock. If you have three or more digital
audio devices, you need to slave them all to a single
master audio clock.
Master
Slave
Figure 3-11: To keep the Traveler phased-locked with other digital
audio devices connected to it, choose a clock master.
Master
SlaveSlave
Also remember that audio phase lock can be
achieved independently of time code (location).
For example, one device can be the time code
master while another is the audio clock master. But
only one device can be the audio clock master. If
you set things up with this rule in mind, you’ll have
trouble-free audio transfers with the Traveler.

DO YOU NEED A SYNCHRONIZER?
Whether or not you’ll need a synchronizer depends
on your gear and what you will be doing with your
Trave l er sy st em . The following pages give you
specific information about common sync
scenarios. At least one of them will likely apply to
you. Here are some general considerations to help
you figure out if you need (or want) a synchronizer
for your Traveler system.
Yo u don’t need a synchronizer if...
As explained earlier, the Traveler’s digital audio
clock must be phase-locked (synchronized) with
other connected digital audio devices to achieve
clean digital transfers between them. Can this be
accomplished without an additional digital audio
synchronizer? It depends on the nature of the other
devices, and what you want to do with them. You
don’t need a synchronizer if the device has a way of
locking itself directly to the Traveler’s clock (via
ADAT lightpipe, S/PDIF, AES/EBU or word clock),
AND if the device carries no sense of location in
time. A digital mixer is a good example: it can slave
to its ADAT lightpipe connection from the Traveler,
and it has no sense of time; it just passes audio
through for mixing.
A stand-alone digital recorder, on the other hand,
does have a sense of location in time, either via
SMPTE time code or via its own sample address.
For example, if you want to fly tracks back and
forth between your computer and an Alesis hard
disk recorder while maintaining the audio’s
position in time, the ADAT Sync port on the
Trave l er le ts you do so without a separate
synchronizer — and with sample-accurate
precision, as long as you’re using AudioDesk,
Digital Performer, or other sample-accurate
software. Just connect the Traveler directly to the
Alesis recorder (or other ADAT Sync-compatible
device) as discussed in “Sample-accurate ADAT
sync with no synchronizer” on page 29. But if you
also want transport control over the entire rig
(including the hard disk recorder) from your audio
software, you’ll need a MIDI Machine Controlcompatible synchronizer such as MOTU’s MIDI
Timepie ce AV, as discussed in “Sample-accurate
sync” on page 27. If you are simply using a standalone recorder as a way to capture live tracks that
you then transfer in one pass into the computer, no
synchronizer is required because the tracks will
remain in perfect phase lock with each other as you
transfer them together. You can simply slave the
stand-alone recorder to the optical output from the
Trave l er as ex pl ai ned in “Syncing optical devices”
on page 32.
Transpor t control from your computer
If you have stand -alone d igital recorders connected
to the Traveler, and they support ADAT Sync, your
audio software — if it supports MIDI Machine
Control (MMC) — allows you to control the
transports of everything from your computer.
Most advanced audio programs support MMC. To
do this, you’ll also need an MMC-compatible
ADAT synchronizer such as a MOTU MIDI
Timepiece AV. Synchronizers like these allow you
to play, stop, rew ind and locate all of your tape
decks using the transport controls in the audio
software. If your audio software supports sampleaccurate sync (like Digital Performer and
Audio Desk), you can do so with sample-accurate
precision. The following pages show you how to
achieve MMC control, where possible.
Continuous sync to SMPTE / MTC
The Traveler can synchronize directly to SMPTE
time code. If your audio software supports sampleaccurate sync (like Digital Performer and
Aud ioDes k), i t ca n also res olve to time code via the
Trave le r. If yo ur sof tw ar e does not support sampleaccurate sync, you need a dedicated synchronizer,
as illustrated on the following pages.

SAMPLE-ACCURATE SYNC
Yo ur Tr av el er s ystem provides you with the most
advanced, accurate synchronization possible with
Alesis modular digital tape decks and hard disk
recorders — or any device that supports sampleaccurate ADAT sync. Figure 3-12 below shows a
few best-case scenarios. Below is a brief
explanation of the benefits you achieve with these
setups.

With sample accurate locating, when you transfer
audio between AudioDesk (or any other sampleaccurate host software) and a sample-accurate
recorder, the audio will not drift in time — even by
as little as one sample. This is the tightest possible
synchronization between digital audio devices.
The timing in your audio w ill not be affe cted in any
way by the process of transferring it between the
Trave l er an d the recorder.
Is your audio software sample-accurate?
Sample-accurate locating is only possible with
software that supports this feature, such as
AudioDesk or Dig ital Performer.
Transpor t control from your computer
If you have a MIDI Timepiece AV, Digital
Timepiece or any ADAT synchronizer that also
supports MIDI Machine Control (MMC), you can
play, stop, rewind and locate all of your ADATs
using the transport controls in the audio software
running on your computer. This includes cueing
features like markers, position bars, playback
wipers, time rulers, etc.

SYNCING TO SMPTE TIME CODE
The Traveler system can resolve directly to SMPTE
time code. It can also generate time code and word
clock, under its own clock or while slaving to time
code. Therefore, the Traveler can act both as an
audio interface and digital audio synchronizer, to
which you can slave other digital audio devices.
Yo u c a n u se the Traveler to slave your audio
software to SMPTE as well, as long as your software
supports sample-accurate sync, which is the means
by which the software follows the Traveler. The
accuracy may not be sample-accurate, but in most
cases it will be very close.

shown to the left.
3. Make sure that Slave to External Sync is checked in the Studio menu.

SYNCING TO VIDEO AND/OR SMPTE TIME
CODE USING A SYNCHRONIZER
If your host audio software does not support the
Tr ave le r’s o n- bo ard SMPTE sync features (because
your software does not support sample-accurate
sync), you need a universal synchronizer, such as a
MOTU MIDI Timepiece AV. These dedicated sync
boxes can read video and SMPTE time code and
then convert it into word clock and MIDI Time
Code (MTC). The word clock goes to the Traveler
to resolve the audio hardware, and MIDI Time
Code is fed to your host audio software, which
locks to it, as shown below in Figure 3-17.
Use this setup if you have:
✓ Video and/or a SMPTE time code source.
✓ A Digital Timepiece, MIDI Timepiece AV or other universal
synchronizer.
✓ Host software that does not support sample-accurate sync
(although you can use this setup even if it does).

SYNCING OPTICAL DEVICES
Mac
The word optical is our short-hand way of referring
to any device that connects to the Traveler via an
optical cable. But we make a further distinction: an
optical device is also one that doesn’t care about
sample location. An example is a digital mixer.
Since a digital mixer is not a recording device, it has
no sense of sample location like an ADAT does. An
ADAT can cue to a specific sample number (e.g.
sample number 43,478, 103) — as can any device
that supports ADAT sync, but most digital mixers
simply mix and process audio digitally, with no
sense of a specific sample location. There are many
other devices that fall into this category, including
digital effects processors, synthesizers, A/D
converters, and many more.
For ADATs or other devices that support ADAT
sync, synchronize them with the Traveler as
described in the previous sections of this chapter.
For optical devices, such as digital mixers, all you
have to do is make sure that their digital audio
clock is phase-locked (in sync with) the Traveler.
There are three ways to do this:
■ Slave the optical device to the Traveler
■ Slave the Traveler to the optical device
■ Slave both the optical device and the Traveler to
a third master clock (such as a Digital Timepiece or
MIDI Timepiece AV synchronizer)

INSTALLING THE TRAVELER HARDWARE
Page 33
SYNCING S/PDIF AND AES/EBU DEVICES
DAT decks an d other devices with S/PDIF and/or
AES/EBU digital I/O will sync to the Traveler in
one of two ways:
■ Via the S/PDIF or AES/EBU connection itself
■ Via word clock
Devices with no word clock
If your S/PDIF or AES/EBU device has no word
clock sync connectors, just connect it to the
Trave l er via t he S/PDIF or AES/EBU connectors.
When the device records a digital audio signal
(from the Traveler), it will simply synchronize to
the clock provided by the digital audio input.
On the other hand, when you transfer audio from
the S/PDIF or AES/EBU device into the Traveler,
you’ll have to slave the Traveler to its S/PDIF or
AES/EBU input. If you have other digital audio
devices connected to the Traveler, and they are not
slaved directly to the Traveler itself, you may hear
clicks and pops resulting from their unsynchronized audio clock. If so, just turn them off during
the transfer.
Devices with word clock
If your S/PDIF or AES/EBU device has a Word
Clock input, slave the device to the Traveler via
their word clock connection. You can then freely
transfer audio between the Traveler and the S/PDIF
device.

have to worry about switching the Clock Source setting depending on the direction of the digital transfer, you can slave the other device to word
clock from the Traveler or vice versa (not shown). The Word Clock connection maintains sync, regardless of the direction of the transfer.

SYNCING WORD CLOCK DEVICES
The Traveler word clock connectors allow you to
synchronize it with a wide variety of other word
clock-equipped devices.
For standard word clock sync, you need to choose
an audio clock master (as explained in “Be sure to
choose a digital audio clock master” on page 25).
In the simplest case, you have two devices and one
is the word clock master and the other is the slave
as shown below in Figure 3-20 and Figure 3-21.

Don’t chain word clock
If you have three or more digital audio devices that
you need to synchronize, avoid chaining their word
clock connections (OUT to IN, OUT to IN, etc.), as
this causes problems. Instead, use a dedicated
synchronizer like the Digital Timepiece or a word
clock distribution device of some kind.
Slaving to 2x and 1/2x word clock
All MOTU FireWire audio interfaces that support
96 and 192 kHz operation (including the 896HD)
have the ability to slave to a word clock signal
running at the 1x sample rate that corresponds to
their current clock rate. For example, the Traveler
could be running at 192 kHz while slaving to a
48 kHz word clock signal from a MOTU MIDI
Timepie ce AV. Simi larly, the Traveler could run at
88.2 kHz and slave to 44.1 kHz word clock. In all of
these cases, the front panel clock LEDs flash both
sample rates to indicate that the Traveler is slaving
to word clock at the corresponding 1x clock rate.
But if the Traveler is running at 96 kHz, it cannot
slave to word clock running at 44.1 kHz.
SYNCING LARGE SYSTEMS
If you are connecting the Traveler to a lot of other
digital audio gear, get a word clock distribution
device, which offers multiple word clock outputs.

Multiple interfaces cannot be bus-powered
Do not run the Traveler under bus power when
connecting it with other devices to the same
FireWire bus. See “Power options” and “Bus power
requirements” on page 20.
Multiple interfaces in the MOTU FireWire Audio
Console
The MOTU FireWire Audio Console displays the
settings for one interface at a time. To view the
settings for an interface, click its tab as shown
below in Figure 3-23.
Figure 3-23: To view the settings for an interface, click its tab.
Synchronizing multiple interfaces
Mac OS X provides an advanced, flexible driver
model that allows multiple Core Audio drivers to
be active at one time, accessed by multiple
applications simultaneously. For example, you can
run both FireWire and PCI audio interfaces at the
same time, accessing all of their inputs and outputs
from your host audio application — or even
multiple applications — simultaneously.
A by-product of this more flexible model is that
multiple devices must be synchronized to one
another in order to remain resolved to each
another. Without synchronization, the audio
streams going to each interface might drift with
respect to one another. For example, the audio
tracks playing back through the Traveler might
drift out of sync with the audio tracks playing back
through your 2408mk3 PCI interface.
Syn chroni zing t hem to each other ensures that they
remain as tightl y and continuously phase-locked as
if they were operating as one unified interface.
INSTALLING THE TRAVELER HARDWARE
35
Page 36
There are two ways to synchronize the Traveler
with other devices, as discussed in the following
sections: via the driver or via word clock.
Resolving to other Core audio drivers
The MOTU FireWire driver has the ability to
resolve to other Core Audio drivers. This allows the
Trave l er, a nd ot her MOTU FireWire interfaces, to
resolve to other audio interfaces running simultaneously on the same computer, such as the Mac’s
built-in audio, a PCI-424 core system, or even
3rd-party interfaces, without the need for external
word clock connections between the devices.
Doing so ensures that audio tracks being played or
recorded by your MOTU FireWire interface will
not drift apart from tracks on the other device
during long playback or recording passes.
Figure 3-24: To resolve a MOTU FireWire interface to another Core
Audio device, choose the other device from the Clock Source menu in
the MOTU FireWire Audio Console. In this example, the Traveler will
slave to the 828mkII.
To s y n chr on iz e mu lt ip le devices via the MOTU
FireWire driver, choose one device (PCI, FireWire
or other wise) as the master clock and then slave the
Trave l er an d o th er FireWire devices to it. All
interfaces will remain resolved to each other via the
master interface.
Make the Clock Source settings for each interface
as follows:
■ For the master interface, click its tab in the
FireWire Console and choose any clock source you
wish (except any of the slave interfaces, of course).
■ For each slave interface, click its tab and choose
the master interface from the Clock Source menu, as
demonstrated below in Figure 3-24. This causes
the slave interfaces to resolve to the master
interface.
If you have multiple Travelers, choose one as the
master, and set its Clock Source to Internal. Then,
click the tab of the other Travelers and set their
Clock Source to the first Traveler.
Resolving to word clock
To r es o lve two Traveler FireWire interfaces with
each other via word clock, choose one as the word
clock master and then slave the second interface to
the first, as shown in Figure 3-22 on page 35. For
three interfaces, you can probably get away with
daisy-chaining them via their word clock
connectors, but this may not always produce the
most reliable results. For three or more devices, a
word clock distribution device is highly
recommended. In this case, the distribution box is
the master, and all FireWire interfaces slave direc tly
to it (instead of to each other).
Connecting other MOTU FireWire interfaces
Yo u can add an original MOTU 828 to the end of a
FireWire daisy chain (because the 828 has only one
FireWire por t), or you can mix and match multiple
828’s with other MOTU FireWire interfaces using a
standard FireWire hub. You can also add 828mkII’s
36
INSTALLING THE TRAVELER HARDWARE
Page 37
or 896HD’s, which have two FireWire ports
convenient for daisy-chaining. Up to four
interfaces can be combined on one FireWire bus.
Operating multiple FireWire interfaces at high
sample rates
Four MOTU FireWire interfaces can operate at
44.1 or 48kHz on a single FireWire bus. At the 2x
samples rates (88.2 or 96kHz) and 4x sample rates
(176.4 and 192kHz), you can operate no more than
three FireWire interfaces on a single FireWire bus.
Adding additional interfaces with a second
FireWire bus
Third-party FireWire bus expansion products in
the form of a cardbus (“PC card”) adaptor or PCI
card allow you to add a second FireWire bus to
your computer. In may be possible to add
additional MOTU FireWire interfaces connected
to such a third-party product, depending on the
performance of the product and the performance
of your host computer.

TRAVELER SETTINGS
Sample Rate
Choose the desired Sample Rate for recording and
playback. The Traveler can operate at 44.1 (the
standard rate for compact disc audio), 48, 88.2, 96,
176.4 or 192kHz. Make absolutely sure that all of
the devices connected digitally to the Traveler
match the Traveler’s sample rate. Also make sure
that your Digital Timepiece, MIDI Timepiece AV
or other digital audio synchronizer matches it as
well. At the 4x sample rates (176.4 or 192kHz), all
digital I/O on the Traveler is disabled.
☛ Mismatched sample rates cause distortion and
crackling. If you hear this sort of thing, check the
sample rate settings in your hardware and here in
the MOTU FireWire Audio Console.
Operation at 4x sample rates (176.4 or 192kHz)
At the 4x sample rates (176.4 or 192kHz),
operation of the Traveler is restricted, due to the
higher audio bandwidth demands, as follows:
■ All digital I/O is disabled (there is no optical,
TOSLink, S/PDIF or AES/EBU input/output).
■ The Traveler provides 8 channels of analog input
and 8 channels of analog output, simultaneously.
■ The Mix1 input, as described in “Mix1 1-2” on
page 65, is not available.
■ The headphone output can be assigned to any
analog output pair or the Phones setting (as
described in “Phones” on page 48). But at the 4x
sample rates, the Phones output is not available
from the computer. Instead, it is only available as a
destination for the four CueMix DSP mixes. In
other words, it can only take CueMix inputs.
■ The main outs mirror the phones.
Clock Source
The Clock Source determines the digital audio
clock that the Traveler will use as its time base. For
a complete explanation of synchronization issues,
44
Figure 5-1: The MOTU FireWire Audio Console gives you access to all of the settings in the Traveler hardware.
MOTU FIREWIRE AUDIO CONSOLE
Page 45
see “Making sync connections” on page 25. The
following sections br iefly discuss each clock source
setting.
Internal
Use the Internal setting when you want the Traveler
to operate under its own digital audio clock. For
example, you may be in a situation where all you
are doing is playing tracks off hard disk in your
digital audio software on the computer. In a
situation like this, you most often don’t need to
reference an external clock of any kind.
Another example is transferring a mix to DAT. You
can operate the Traveler system on its internal
clock, and then slave the DAT deck to the Traveler
via the S/PDIF connection (usually DAT decks
slave to their S/DIF input when you choose the
S/PDIF input as their record source) or via the
Trave le r’s word cl ock ou tp ut (if your DAT de ck h as
a word clock input).
If you would like help determining if this is the
proper clock setting for your situation, see “Do you
need a synchronizer?” on page 26.
For further details about this setting, see “Syncing
S/PDIF and AES/EBU devices” on page 33.
S/PDIF
The S/PDIF clock source setting refers to the
S/PDIF RCA input jack on the Traveler. This
setting allows the Traveler to slave to another
S/PDIF device.
Use thi s setting whenever you are recording input
from a DAT deck or other S/PDIF device into the
Trave l er. It is not necessary in the opposite
direction (when you are transferring from the
Trave l er to th e DAT machine).
For further details about this setting, see “Syncing
S/PDIF and AES/EBU devices” on page 33.
Wor d C l oc k In
The Wor d C loc k I n setting refers to the Word Clock
In BNC connector on the Traveler rear panel.
Choosing this setting allows the Traveler to slave to
an external word clock source, such as the word
clock output from a digital mixer or another
Tr a v e l e r.
With ADAT devices, however, you usually want an
external digital audio synchronizer, such as the
MIDI Timepiece AV or Digital Timepiece, to be the
digital clock master. In this case, you would set the
Trave l er cl oc k s ource setting to ADAT 9-pin, as
described below.
AES/EBU
The AES/EBU clock source setting refers to the
AES/EBU XLR input jack on the Traveler. This
setting allows the Traveler to slave to another
AES/EBU device.
Use thi s setting whenever you are recording input
from a DAT deck or other AES/EBU device into the
Trave l er. It is not necessary in the opposite
direction (when you are transferring from the
Trave l er to th e DAT machine).
MOTU FIREWIRE AUDIO CONSOLE
ADAT 9-pin
The ADAT 9-pin clock source setting refers to the
ADAT digital audio synchronization format. It
allows the Traveler to slave to an ADAT — or ADAT
sync chain — via its ADAT sync 9-pin connector.
ADAT sync also carries precise, sample location
information, which allows AudioDesk and Digital
Perfor mer to transfer audio to and from ADAT-
sync compatible recorders without drifting by as
much as one sample.
Use thi s setting when you are using the Traveler
with one or more ADAT-s yn c c ompatible
recorders. Make sure the Tr a v e le r i s connected to
the end of the ADAT sync chain.
45
Page 46
Yo u s h o u ld also use this setting if you have a MIDI
Timepiece AV, which allows you to drive your
entire system from the transport controls of
AudioDesk, Digita l Perfor mer or other computer
software.
Yo u c ou ld also use ADAT sync to continuously
resolve the Traveler to SMPTE time code, video,
and word clock via a synchronizer like the MOTU
MIDI Timepiece AV. Word clock can accomplish
the same thing.
For further details, see “Sample-accurate ADAT
sync” on page 28, “Sample-accurate ADAT sync
with no synchronizer” on page 29 and “Syncing to
video and/or SMPTE time code using a
synchronizer” on page 31.
ADAT optical
The ADAT optical clock source setting refers to the
clock provided by the Traveler’s optical input,
when it is connected to an ADAT optical device.
This setting can be used to slave the Traveler
directly to the optical input connection. Most of
the time, you can set up a better operating scenario
that uses one of the other synchronization options.
However, the re may be occasions when you have an
ADAT optical compatible device that has no way of
synchronizing digitally to the Traveler or an
external synchronizer such as the Digital
Timepiece. In this case, the ADAT Optical clock
source setting lets you slave the Traveler to the
device itself via its digital input to the Traveler.
If the ADAT Optical setting does not appear in the
menu, it means that the Traveler’s optical input is
currently either turned off or set to the TOSLink
format. In either case, choose the ADAT optical
format f rom the Optical input menu (Figure 5-1 on
page 44).
reference and shared transport control are not
needed — without having to set up an elaborate
synchronization scenario.
For further details about this setting, see “Syncing
optical devices” on page 32.
TOSLink
The TOSLink clock source setting refers to the
clock provided an optical S/PDIF device connected
to the Traveler’s optical input. This setting can be
used to slave the Traveler directly to the optical
input connection. Most of the time, you can set up
a better operating scenario that uses one of the
other synchronization options. However, there
may be occasions when you have an TOSLink-
compatible device that has no way of
synchronizing digitally to the Traveler or an
external synchronizer such as the Digital
Timepiece. In this case, the TOSLink clock source
setting lets you slave the Traveler to the other
device via the Traveler’s optical input.
If the TOSLink setting does not appear in the
menu, it means that the Traveler’s optical input is
currently either turned off or set to the ADAT
optical format. In either case, choose the TOSLink
format f rom the Optical input menu (Figure 5-1 on
page 44).
This setting is also useful if you just need to make a
simple, click-free digital transfer between the
Trave l er an d a no ther device — where a time code
reference and shared transport control are not
needed — without having to set up an elaborate
synchronization scenario.
For further details about this setting, see “Syncing
optical devices” on page 32.
This setting is also useful if you just need to make a
simple, click-free digital transfer between the
Trave l er an d a no ther device — where a time code

SMPTE
Choose this setting to resolve the Traveler directly
to SMPTE time code (LTC) being received via any
analog input on the Traveler. For details, see
“Syncing to SMPTE time code” on page 30 and
chapter 12, “FireWire SMPTE Console” (page 87).
Macintosh built-in
Choose this setting to resolve the Traveler to your
Mac’s built-in audio. Doing so will ensure that
audio streams playing back from or recorded by
the Traveler will not drift apart from audio streams
simultaneously played or recorded by the Mac’s
built-in mic, speakers or audio output. For
complete details, see “Resolving to other Core
audio drivers” on page 36.
Other audio devices (drivers)
The MOTU FireWire Audio Drive r has the ability
to resolve to other Core Audio drivers. Doing so
will ensure that audio stream s playing back from or
recorded by the Traveler will not drift apart from
audio streams simultaneously played or recorded
by the other devices. For complete details, see
“Resolving to other Core audio drivers” on
page 36.
Default Stereo Input/Output
In the System Preferences window, Mac OS X lets
you choose third-party hardware such as the
Trave l er fo r yo u r M a ci ntosh sound input and
output. The system input and output can be used
for alert sounds and general audio I/O for
applications like iTunes, iMovie, etc.
Figure 5-2: The Mac OS X sound preferences let you use the Traveler
for general stereo audio input and output for your Mac.
The Default Stereo Input and Default Stereo Output
settings in the MOTU FireWire Console
(Figure 5-1 on page 44) let you specify the stereo
input and output on the Traveler to be used when it
is chosen as the audio I/O device in the system
preferences.
☛ Note: The Default Stereo Input/Output
settings have the following system software
requirements:
MOTU FIREWIRE AUDIO CONSOLE
■ Mac OS X 10.2.x together with QuickTime 6.4
OR
■ Mac OS X 10.3 (aka Panther) or later
47
Page 48
If your Macintosh system software does not meet
these minimum requirements, the Default Stereo
Input/Output options do not appear in the MOTU
FireWire Console window.
Optical input/output
The Optical input and Optical output settings let
you cho ose be tween ADAT optical (‘lightpipe’) and
S/PDIF optical (‘TOSLink’) as the format for the
Trave l er ’s o pt ic al input and output. Choose the
format that matches the device connected. If you
are not using the optical connections, it is
recommended that you turn them off (as provided
in the menus) to reduce bandw idth and processing
overhead. Note that you can operate the input and
output independently. For example, you could use
the ADAT optical format on the input (with a
digital mixer, for example) and optical S/PDIF on
the output (with a DAT deck, for example).
When the optical output is set to TOSLink, the
signal is split to both the RCA and optical output
jacks. However, when the optical input is set to
TOSLink, the RCA S/PDIF jack is disabled.
Phones
The Phones setting lets you choose what you will
hear from the headphone jack. Choose Analog 1-2
if you’d like the headphone output to match the
main outs. Choose Phones 1-2 if you would like the
headphones to serve as their own independent
output, which you can access as an independent
output destination in your host audio software and
as an output destination for the four on-board
CueMix DSP mix busses.
At the 4x sample rates (176.4 and 192kHz), the
headphone output can be assigned to any analog
output pair or the Phones 1-2 setting, as described
above. But at the 4x sample rates, the Phones
output is not available as an output destination for
software on the computer. Instead, it is only
available as a destination for the two CueMix DSP
mixes. In other words, it can only take CueMix
inputs.
Word Out
If you are running a Traveler interface at a high
sample rate (88.2, 96, 176.4 or 192kHz), the Wo r d
Out menu appears in the interface tab (as shown in
Figure 5-1 on page 44). This menu lets you choose
a word clock output rate that either matches the
global sample rate (e.g. 176.4 or 192kHz) or
reduces the word clock output to the
corresponding 1x rate (either 44.1 or 48kHz). For
example, if the Traveler is operating at 176.4kHz,
choose Force 44.1/48kHz to produce word clock
output at 44.1kHz.
To m atc h the Traveler’s sample rate, choose System
Clock. To reduce the word clock rate to the
corresponding 1x rate, choose Force 44.1/48kHz.
‘GENERAL’ TAB SETTINGS

This setting applies to other MOTU FireWire audio
interfaces, but it does not apply to the Traveler.
Launch console when hardware becomes
available
Check this option if you would like the MOTU
FireWire Audio Console icon to appear in the
application dock as soon as a MOTU FireWire
interface is detected (switched on, plugged in, etc.)
Edit Channel Names
Click the Edit Channel Names button to open the
Channel Names window (Figure 5-3). This
window lets you edit the names of the Traveler
inputs and outputs, as they appear in your host
audio software. For example, when you click on a
menu that displays the Traveler inputs (or outputs),
you will see the names you specify in this window
(e.g. “vocal mic”, “lead guitar”, etc.), instead of the
default generic names (“Analog 1”, “Analog 2”,
etc.)
48
MOTU FIREWIRE AUDIO CONSOLE

OS X’s port naming features. Secondly, this feature
has the following system software requirements:
■ Mac OS X 10.2.x together with QuickTime 6.4
OR
■ Mac OS X 10.3 (aka Panther) or later
If your Macintosh system software does not meet
these minimum requirements, the Default Stereo

Setup mode
In setup mode, the LCD displays basic settings,
such as clock source, optical I/O format (ADAT
versus TOSLink), and so on. These settings are
covered in detail later in “SETUP / SELECT” on
page 52.
Figure 6-2: In setup mode, the LCD displays a setup parameter in the
top row of the LCD and the current setting in the bottom row.
Mixer mode
In mixer mode, the LCD displays the settings for
the current Traveler mix being shown in the
display, as demonstrated in Figure 6-1 on page 51.
Parameter “zooming”
For many settings, the LCD temporarily “zooms
in” to display a long-throw meter and alphanumeric display to give you precise, real-time
feedback as you adjust the setting. For example, if
you change the headphone volume, the LCD will
display a level meter and gain reduction reading
that updates as you turn the volume knob. After a
brief time-out, the display returns to its previous
state before you turned the volume knob. The
time-out period can be adjusted, as explained later
in the section called “Fader View Time”.
Figure 6-3: For many settings, the LCD “zooms in” on the setting as
you adjust it.
VOLUME
The VOLUME knob lets you control the volume of
both the headphone jack and the rear-panel main
outs. Press the knob to toggle between the
headphones and the main outs. As explained in the
previous section, the LCD provides detailed
feedback as you turn the knob. To view the current
setting without changing it, just push the knob
(without turning it).
SETUP / SELECT
Press the MIX/SETUP knob to toggle between
mixer mode and setup mode. In mixer mode, the
SETUP and SELECT knob do nothing. In setup
mode, turn SETUP to choose a setting and
SELECT to change it. In some cases, SELECT
chooses one of the Traveler’s four mixes, and the
VA LU E k no b c ha n g e s t h e setting. The setup
settings are briefly explained below.
Clock source
This sets the global clock source for the Traveler
and is the same as the Clock Source setting in the
MOTU FireWire Audio Console as explained in
“Clock Source” on page 44. If the Traveler is
currently connected to a computer, this setting
cannot be changed from the front-panel LCD. It
must be changed in the MOTU FireWire Audio
Console instead. Or, you can disconnect the
Trave l er fr om th e c om p ut er to change the Clock
Source from the front panel.
Word Clock Out
If you are running a Traveler interface at a high
sample rate (88.2, 96, 176.4 or 192kHz), the Wo r d Clock Out setting lets you choose a word clock
output rate that either matches the global sample
rate (e.g. 176.4 or 192kHz) or reduces the word
clock output to the corresponding 1x rate (either
44.1 or 48kHz). To match the Traveler’s sample
rate, choose Follows System. To re duce the word
clock rate to the corresponding 1x rate, choose
Force 44/48.

Fader View Time
The Fader View Time option lets you control the
length of time that an adjusted parameter remains
displayed in the LCD before the LCD returns to its
previous state. For example, when you turn the
MIX BUS knob to adjust the volume of the current
mix, you’ll see a long-throw horizontal fader in the
LCD, along with a numeric display of the current
gain reduction. After you stop turning the knob,
this fader remains displayed in the LCD for a
moment before the LCD returns to its previous
state. The Fader View Time option lets you control
how long the adjusted parameter remains on the
LCD after the knob stops turning.
Optical In / Optical Out
These two settings determine the format for the
Trave l er ’s o pt ic al input and output. They are the
same as the optical setting in the MOTU FireWire
Audio Console as explained in “Optical input/
output” on page 48. To change the setting, turn the
SELECT knob, and then push it to confirm your
choice.
Bus output
The Bus Output setting lets you choose the Traveler
output pair for each of the four CueMix DSP mix
busses. Turn the SELECT knob to choose a bus.
Tur n t he VALU E k nob to choose an output. Push

to another mix. Turn the SELECT knob to choose a
mix. Push SELECT to paste. The word Done
appears briefly to confirm the paste. The following
mix parameter are included in the paste operation:
Gain, Pan, Solo, Mute, +4/-10, +6dB boost, and
stereo pairing. The following mix parameters are
not pasted: Bus output, Bus mute and Bus gain.
Save/Name Preset
The Save/Name Preset setting lets you name and
save up to sixteen separate Traveler presets. A
preset holds all of the current CueMix DSP mix
settings for all four mix busses. Setup parameters
are not included. The name can have up to 12
characters. Here is a summary of how to name and
save a preset:

All Notes Off
The All Notes Off setting sends a MIDI All Notes Off
message, as well as a MIDI note-off message for
every note on every MIDI channel. This stops any
stuck notes that are currently playing. Push
SELECT to initiate the All Notes Off operation. The
MIDI OUT LED will glow to confirm that the noteoff data is being sent.
Fac tory Defaults
The Factory Defaults setting restores the Traveler
factory settings. Push SELECT to initiate the
operation, and then when the LCD asks “Are you
sure?”, push VALUE to execute it.
MIX BUS
The Traveler on-board CueMix DSP mixer
provides four stereo mix busses, named MIX1,
MIX2, MIX3 and MIX4, respectively. Each mix bus
(also referred to as a “mix”) independently mixes
all inputs (or any subset of your choosing) down to
one Traveler output pair of your choosing. For
example, you could assign MIX1 to the main outs,
MIX2 to analog outputs 1-2 and MIX3 to the
headphone outs. You can then independently
assign any input to any mix. An input can even be
included in two or more mixes simultaneously at
different input levels.
Figure 6-4: In mixer mode, the LCD displays the mix settings for the
mix bus currently being displayed in the LCD.

knob to toggle a stereo input pair
between separate mono inputs
(blank) or a stereo pair (“[ ]”). Or
turn the knob to toggle. When a pair
of inputs are linked, all of their mix
settings become linked (gain, solo,
etc.) except for pan. When the pair is
first created, pan is set to hard left
and hard right, but the channels can
then be further modified independently. When a pair is unlinked, the
channels are set to pan-center.
Mix parameters that apply across all mixes
The last three mix settings (input reference level,
+6dB software boost, and stereo pairing) apply
across all mixes because they have to do with the
nature of the input itself. For example, if you have
an input that requires a -10dB reference level, then
you’ll want the reference level to apply to all mixes.
Working with stereo pairs
When you group a pair of inputs as a stereo pair, all
of their mix settings become linked, and whenever
you scroll to either channel, both channels will
flash to indicate that they will operate as a linked
stereo pair. Note that when a pair is first created,
pan is set to hard left and hard right, but the
channels can then be further modified independently. When a pair is unlinked, the channels are
set to pan-center.
CURSOR / VALUE
When the LCD display is in mixer mode, the
CURSOR knob scrolls left and right over the 20
inputs displayed in the LCD. The current input
flashes. As a shortcut, you can push the CURSOR
knob to toggle between the top row (analog inputs)
and bottom row (digital inputs). The VALUE knob
changes the current mix parameter for the
currently flashing input. In some cases, such as
Gain and Pan, the LCD will “zoom” to the enlarged
horizontal fader while you adjust it w ith the VALUE
knob. After you stop adjusting, the LCD will return
to the mixer display.
STAND-ALONE OPERATION
All settings, including all mix settings and global
settings, are saved in the Traveler’s memory, and
they remain in effect even when the Traveler is not
connected to a computer. This allows you to use the
Trave l er as a s tand -a lo ne 8-bus mixer. You can
make adjustments to any setting at any time from
the front panel.

device by choosing Configure Audio System>Configure Hardware Dr iver from the Setup
menu. This window shows some of the Traveler
settings, such as sample rate and clock source, but
to access all of the Traveler settings, open the
MOTU FireWire Audio Console, as shown in
Figure 5-1 on page 44.
Figure 7-1: Choose Setup menu> Configure Audio System> Configure

Sample rate
Choose the desired overall sample rate for the
Trave l er sy st em and Digital Performer. Newly
recorded audio in Digital Performer will have this
sample rate. Imported audio or soundbites in
existing files that do not match this sample r ate wi ll
be displayed in the Soundbites window with a red
‘X’ on its move handle to indicate that it cannot be
played.

192kHz)” on page 44.
microphones, and so on connected to the analog
inputs of the Traveler. If so, you will often be
mixing their live input with audio material
recorded in Digital Performer. See chapter 10,
“Reducing Monitoring Latency” (page 73) for
complete details.
Optical input and output
To m ak e a Tr a v el e r opt ica l input or out put ava ilabl e
in Digital Performer, choose the appropriate
format (ADAT optical or TOSLink) from the optical
input and/or output menu. If you won’t be using
the optical connectors, turn them off.
Clock Source
This setting is very important because it
determines which audio clock the Traveler will
follow.
If you do not have any digital audio connections to
your Traveler (you are using the analog inputs and
outputs only), and you will not be slaving Digital
Perfor mer to external SMPTE time code, choose
Inter nal.
If you are slaving the Traveler to the ADAT sync
Input connector, cho ose ADAT 9-pin.
If you are slaving the Traveler and Digital
Perfor mer to SMPTE time code via the Traveler
itself, choose SMPTE and follow the directions in
“Syncing to SMPTE time code” on page 30.
If you have digital audio devices connected to the
Trave l er, o r i f you a re not sure about the clock
source of your setup, be sure to read “Making sync
connections” on page 25 and “Clock Source” on
page 44.
Buffer Size
The Buffer Size setting can be used to reduce the
delay — or monitoring latency — that you hear
when live audio is patched through your Traveler
hardware and Digital Performer. For example, you
might have MIDI instruments, samplers,
58
Phones
This Traveler setting lets you choose what you’ll
hear from the headphone jack. For example, if you
choose Analog 1-2, the headphones will duplicate
the main outs. Or you can choose any other output
pair. If you choose Phones 1-2, this setting makes
the headphone jack serve as its own independent
output pair (except when running at 176.4 or
192kHz). As a result, you’ll see Phones 1-2 as an
additional audio destination in Digital Performer’s
audio output menus.
BE SURE YOU HAVE ENOUGH VOICES
Go to the Setup menu and choose Configure Audio
System>Configure Studio Size. Then check to make
sure you have enough mono and stereo audio
voices to cover the 20 channels of input and 22
channels of output provided by your Traveler —
although the number of channels may depend on
how your Traveler is configured:
■ 10 channels for analog I/O (including the
headphone out)
■ 2 channels for RCA S/PDIF
■ 2 channels for AES/EBU
■ Zero, 2 or 8 channels for optical, depending on
whether you have optical turned off, or set to
TOSLink or ADAT optical

For example, if you are using analog only, you only
need 10 channels. If you are using analog and RCA
S/PDIF, you need 12 channels.
assigned to this output pair will be heard on the
headphone jack only. For further explanation, see
“Phones” on page 48.
As another example, if you are using analog, RCA
S/PDIF, AES/EBU and ADAT optical, you need 22
channels (the maximum number of simultaneous
output channels provided by the Traveler).
TRI MMING THE MIC/INSTRUMENT INPUTS
The Traveler mic/instrument inputs provide trim
knobs on the front panel. To calibrate an audio
input:
1 Record-enable a track in Digital Performer.
2 Choose the desired Traveler mic input for the
track.
3 Open the Audio Monitor window.
4 As you feed signal to the input, adjust the input’s
corresponding trim knob on the front panel of the
Tr av el er u nt il peaks in the level meter are as high as
possible without clipping (hitting zero dB).
WORKING WITH TRAVELER INPUTS AND
OUTPUTS
Once you’ve enabled the MOTU FireWire Audio
driver as explained earlier in “The Traveler
settings” on page 57, Traveler audio inputs and
outputs will appear in Digital Performer’s audio
input and output menus. If you don’t see the optical
inputs and/or outputs, check the MOTU FireWire
Audio Console to ma ke sure they are turned on
and set to the format you require. If you don’t plan
to use the optical input or output, turn it off to
conserve computer bandwidth.
Phones 1-2
If you’ve chosen to treat the Traveler headphones as
an independent output, you’ll see Phones 1-2 in
Digital Performer’s output menus. Audio tracks
Mix1 1-2
In Digital Performer’s audio input menus, you’ll see
a Traveler input called Mix1 1-2. This input source
delivers the output of CueMix DSP “MIX1” (the
first mix bus of the four on-board no-latency
monitor mixes in the Traveler) back to your
computer. This input serves, for example, as a
convenient way for you to record the Traveler’s
MIX1 monitor mix back into Digital Performer
(for reference and archiving purposes). Further, if
you are sending audio from Digital Performer to
the same output pair as MIX1, you can choose to
either include or exclude the audio from the
computer in the stream being sent back to Digital
Perfor mer. For details on how to do this, see “Mix1
Return Includes Computer” on page 84.
The Mix1 1-2 input is not available at the 4x sample
rates (176.4 or 192kHz).
☛ War ni n g: th e Mi x1 1-2 input can cause
feedback loops! DO NOT assign this input to a
track that shares the same Traveler output pair as
MIX1.
24-BIT OPERATION
Yo ur Tr av el er h ardware fully supports Digital
Per former’s 24-bit recording capabilities, including
both analog and digital 24-bit recording. If you
would like to record and play back 24-bit audio
files, go to the Setup menu, choose Configure Audio System>Configure Sample Format, and choose
24-bit recording as the sample format. This setting
is saved with the Digital Performer project.
FINE-TUNING I/O TIMING
The Traveler has the ability to be sample accurate.
This means that when you transfer audio between
Digital Performer and an ADAT (or other ADATsync compatible recorder), for example, you can
DIGITAL PERFORMER
59
Page 60
record the audio back and forth as many times as
you want between them and it will remain exactly
at its original sample location (unless you move it
in Digital Performer, of course).
Occasionally, you may encounter a situation in
which you observe a slight offset of one sample —
or maybe a few — caused by inherent latencies in
the devices you are using with the Traveler. Usually,
these offsets will be consistent, and you can
compensate for them in Digital Performer. To do
so, choose Configure Audio System>Fine-tune Aud io I /O Timing f rom the Set up m enu as shown i n
Figure 7-2.
Figure 7-2: Fine-tuning the timing of audio playback and recording.
SYNCHRONIZATION
Digital Performer can run under its own transport
control or slave to an external sync source, such as
SMPTE time code or ADAT sync (sample address).
Running DP under its own transport control
If you do not need to synchronize Digital
Perfor mer with time code or another recording
device, such as a tape deck, just leave the Slave to External Sync command in the Studio menu
unchecked.
make sure that their audio clocks are phase-locked.
For details, see “Syncing optical devices” on
page 32 and “Making sync connections” on
page 25. If you don’t have any digital audio devices
connected to the Traveler, digital audio phase-lock
does not apply to you.
Resolving DP and the Traveler to SMPTE time
code
If you need to slave Digital Performer and the
Trave l er to SMPTE time code, you can do so with
or without a dedicated synchronizer.
Resolving directly to time code (with no
synchronizer)
To r es o lve yo ur D ig it a l Pe rformer/Traveler system
directly to SMPTE time code with no additional
synchronization devices, use the setup shown in
“Syncing to SMPTE time code” on page 30.
Choose Receive Sync from the Setup menu and
choose the Sample accurate option. Then make
sure that the Slave to External Sync command in the
Studio menu is checked. Make sure the Clock Source setting in the MOTU FireWire Audio
Console window is set to SMPTE. Also, make sure
that you’ve connected an LTC input signal to a
Tr av el e r a n al og i nput, and that you’ve specified t hat
input in the SMPTE Console.
Resolving to video and/or time code with a
dedicated synchronizer
To r es o lve yo ur D ig it a l Pe rformer/Traveler system
to video and/or SMPTE time code using an
additional synchronization device, use the setup
shown in “Syncing to video and/or SMPTE time
code using a synchronizer” on page 31.
However, even though Digital Performer is not
slaving to external sync, you still need to be
concerned with the synchronization of the
Trave l er ’s d ig ita l au di o c lo ck with ot he r d ev ices
connected to it digitally (if any). For example, if
you have a digital mixer connected to the Traveler
via an ADAT optical lightpipe cable, you need to

Choose Receive Sync from the Setup menu and
choose the MTC (MIDI Time Code) option. Then
make sure that the Slave to External Sync command
in the Studio menu is checked. To ensure that your
audio tracks don’t drift out of sync with your MIDI
tracks — or time code, use a hardware
synchronizer like the MIDI Timepiece AV or
DIGITAL PERFORMER
Page 61
Digital Timepiece to resolve the Traveler hardware
as well, as shown in Figure 3-17 on page 31. A
digital audio synchronizer is required for drift-free
SMPTE/MIDI time code sync. Make sure the Clock Source setting in the MOTU FireWire Audio
Console window has the appropriate setting for
locking the Traveler to the synchronizer. For
example, in Figure 3-17 on page 31, word clock is
being used to resolve the Traveler, so the Clock
Source setting is Word Cl ock In.
☛ If you have an ADAT sync compatible device,
don’t use SMPTE time code. Instead, use sampleaccurate sync as described in the next section.
Sample-accurate sync to ADAT and Tascam
To g et h er, Di gi tal Pe rf or mer and the Traveler
provide you with sample-accurate transfers with
ADATs, Alesis recorders and any other devices that
support standard ADAT sample address (ADAT Sync).
Similarly, with the help of a MOTU Digital
Timepiece, Digital Performer and a Traveler can
perform sample-accurate transfers with Tascam
digital recorders.
A sample-accurate transfer is one in which the
original location of the audio is preserved in the
transfer, down to the sample.
For details on how to set up sample-accurate sync,
see “Sample-accurate sync” on page 27. Be sure to
choose the Sample Accurate Sync option in Digital

To c ont ro l t he t r ansports of everything together
from Digital Performer, see the next section.
MIDI MACHINE CONTROL (MMC)
If you have ADATs an d a M MC -compatible ADAT
synchronizer like the MIDI Timepiece AV or
Digital Timepiece, you can control everything
from your computer screen with Digital
Perfor mer’s transport controls and cueing features
(like Markers, the playback wiper, etc.)
Similarly, if you have Tascam recorders and a
MOTU Digital Timepiece (or other MMCcompatible Tascam synchronizer), can control all
of your Tascam decks (in ABS time) in a similar
fashion from Digital Performer.
See the MIDI Machine Control chapter in your
MIDI Timepiece AV or Digital Timepiece manual
for details on how to set this up.
MIDI I/O VIA THE TRAVELER MIDI PORTS
Once you’ve followed the procedure for enabling
the Traveler’s MIDI features as explained in
“Software installation for Mac OS X” on page 39,
the Traveler MIDI ports will appear as a input
source and output destination in Digital
Perfor mer’s MIDI I/O menus.
PROCESSING LIVE INPUTS WITH PLUG-INS
If you patch a live input (such as MIDI synthesizer)
through a plug-in effect in Digital Performer, you
might hear a slight delay. There are several ways to
reduce this delay. F or d e t ai l s , see chapter 10,
“Reducing Monitoring Latency” (page 73).
EXCHANGING PROJECTS WITH AUDIODESK
DP4 can exchange projects with AudioDesk. To
open an AudioDesk project in Digital Performer,
open it in same way you would a DP project. To
export a project to AudioDesk, use DP4’s Save As

Trave l er sy st em and your host audio software.
Newly recorded audio will have this sample rate.
Before running the Traveler at the 4x sample rates,
see “Operation at 4x sample rates (176.4 or
192kHz)” on page 44.
Clock Source
This setting is very important because it
determines which audio clock the Traveler will
follow.

Page 70
If you do not have any digital audio connections to
your Traveler (you are using the analog inputs and
outputs only), and you will not be slaving your host
software to external SMPTE time code, choose
Inter nal.
If you wish to slave the Traveler to the ADAT sync
Input connector, cho ose ADAT 9-pin. Note that
this port will only work properly as a clock source
for Mac OS X audio applications that support
sample-accurate sync (such as AudioDesk and
Digital Performer).
If you have digital audio devices connected to the
Trave l er, o r i f you a re not sure about the clock
source of your setup, be sure to read “Making sync
connections” on page 25 and “Clock Source” on
page 44.
Optical input and output
To m ak e a Tr a v el e r opt ica l input or out put ava ilabl e
in your host software, choose the appropriate
format (ADAT optical or TOSLink) from the optical
input and/or output menu. If you won’t be using
the optical connectors, turn them off.
There will be a menu there that lets you choose
among various drivers that may be in your system.
Choose the MOTU Traveler from this menu.
Logic Audio
In Logic audio, go to the Preferences window, click
the Audio icon click the Drivers tab and click the
Core Audio tab as shown below. Choose the MOTU
Tr av e l e r from the Driver menu. For information
about the I/O Buffer Size setting, see “Adjusting the
audio I/O buffer” on page 75.
Phones
This Traveler setting lets you choose what you’ll
hear from the headphone jack. For example, if you
choose Main Outs, the headphones will duplicate
the main outs. Or you can choose any other output
pair. If you choose Phones, this setting makes the
headphone jack serve as its own independent
output pair. As a result, you’ll see Phones 1-2 as an
additional audio destination in your host audio
software’s audio output menus.
CHOOSING THE MOTU FIREWIRE CORE
AUDIO DRIVER
Once you’ve made the preparations described so
far in this chapter, you’re ready to run your audio
software and enable the MOTU Traveler Core
Audio driver. Check the audio system or audio
hardware configuration window in your software.

inputs and outputs within Cubase or Nuendo as
usual. For information about the Audio Buffer Size
setting, see “Adjusting the audio I/O buffer” on
page 75.

Most programs will likely address this issue in
future updates. In the meantime, here is how you
can identify each input and output. Inputs are
always listed in the same order as follows:
Figure 9-3: Enabling the Traveler audio driver in Cubase SX.
Other audio software
For other audio applications, the procedure is
similar to that shown above for Cubase and Logic.
Consult your owner’s manual for further
information.
AUDIO INPUT AND OUTPUT NAMES
The Traveler Core Audio driver supplies text string
labels for its inputs and outputs to clearly identify
each one, but some applications do not display
these labels. For example, in Cubase SX, the
Trave l er ou t pu ts ar e numbered like this:

As an example, the AES/EBU inputs will always be
listed as inputs 9-10. As another example, ADAT
output channels 1-2 will be listed as channels
15-16, unless the phones are mirroring the main
outs (or another output), in which case ADAT
outputs 1-2 would be listed as channels 13-14.

Page 72
The ‘Mix1’ input pair
The Mix1 input pair delivers the output of CueMix
DSP “MIX1” (the first mix bus of the four onboard no-latency monitor mixes in the Traveler)
back to your computer. This input serves, for
example, as a convenient way for you to record the
Trave l er ’s M IX1 monitor mix back into your host
audio software (for reference and archiving
purposes). Further, if you are sending audio from
your host audio s oftware to the same output pair as
MIX1, you can choose to either include or exclude
the audio from the computer in the stream being
sent back to the computer. For details on how to do
this, see “Mix1 Return Includes Computer” on
page 84.
The Mix1 1-2 input is not available at the 4x sample
rates (176.4 or 192kHz).
■ Zero, 2 or 8 channels for optical, depending on
whether you have optical turned off, or set to
TOSLink or ADAT optical
For example, if you are using analog only, you only
need 10 channels. If you are using analog and RCA
S/PDIF, you need 12 channels.
As another example, if you are using analog, RCA
S/PDIF, AES/EBU and ADAT optical, you need 22
channels (the maximum number of simultaneous
output channels provided by the Traveler).
PROCESSING LIVE INPUTS WITH PLUG-INS
If you patch a live input (such as MIDI synthesizer)
through a plug-in effect in your host software, you
might hear a slight delay. There are several ways to
reduce this delay. F or d e t ai l s , see chapter 10,
“Reducing Monitoring Latency” (page 73).
☛ War ni n g: th e Mi x1 inpu t can cause feedback
loops! DO NOT assign this input to a track that
shares the same Traveler output pair as MIX1.
Phones 1-2
If you’ve chosen to treat the Traveler headphones as
an independent output, they appear in your host
software as an independent output pair. Audio
tracks assigned to this output pair will be heard on
the headphone jack only. For further explanation,
see “Phones” on page 48.
NUMBER OF CHANNELS
If your host audio software requires that you
specify the number of audio voices or channels you
will be using, be sure to choose enough channels to
cover the 20 inputs and 22 outputs provided by
your Traveler — although the number of channels
may depend on how your Traveler is configured:
■ 10 channels for analog I/O (including the
headphone out)
■ 2 channels for RCA S/PDIF
SYNCHRONIZATION
As of Version 10.3.6, Mac OS X does not allow
third-party applications to take advantage of the
Trave l er ’s s am pl e-accurate sync features or onboard SMPTE sync features. Refer to
www.motu.com for further developments.
However, if most applications that support exter nal
sync will be able to supports the Traveler’s word
clock sync capabilities. Consult chapter 3,
“Installing the Traveler Hardware” (page 17) and
use the synchronization diagrams in that chapter
to synchronize your software and the Traveler to
the other components of your system.

CHAPTER
10Reducing Monitoring Latency
OVERVIEW
Monitoring latency is that slight delay you hear
when you run an input signal through your host
audio software. For example, you might hear it
when you drive a live mic input signal through a
reverb plug-in running in your audio sequencer.
This delay is caused by the amount of time it takes
for audio to make the entire round trip through
your computer, from when it first enters a Traveler
input, passes through the Traveler hardware into
the computer, through your host audio software,
and then back out to a Traveler output.
If you don’t need to process a live input with
plug-ins, the easiest way to avoid monitoring
latency is to use the Traveler’s CueMix DSP feature
to patch the input directly to your monitor outs via
the Traveler audio hardware. This is just like
bussing inputs to outputs in a digital mixer. For
details, see “CueMix DSP hardware monitoring”
on page 77.
If you do need to process a live input with plug-ins,
or if you are playing virtual instruments live
through your Traveler audio hardware, you can
significantly reduce latency — and even make it
completely inaudible, regardless of what host audio
application software you use. This chapter explains
how.
Controlling CueMix DSP from your audio software . . 77
It is i mpor tant to note that m onitoring delay h as no

played back from disk. Actual recording and
playback is extremely precise.

Page 74
MONITORING LIVE INPUT
There are two ways to monitor live audio input
with a Traveler: 1) through the computer or 2) via
CueMix™ DSP hardware monitoring. Figure 10-1
on page 74 shows method 1, which allows you to
add effects processing such as reverb and guitar
amp effects via plug-ins in your audio software. See
the next section, “Adjusting the audio I/O buffer”
for details about how to reduce — and possibly
eliminate — the audible monitoring delay that the
computer introduces.
Figure 10-2 shows how to use CueMix™ DSP
hardware-based monitoring, which lets you hear
what you are recording with no monitoring delay
and no computer-based effects processing. (You
can add effects later, after you’ve recorded the live
input as a disk track.) See “CueMix DSP hardware
monitoring” later in this chapter for details on how
to use CueMix DSP with your audio software, or
with the included CueMix Console software.
If the material you are recording is suitable, there is
a third way to monitor live input: use both methods
(Figure 10-1 and Figure 10-2) at the same time. For
example, you could route vocals to both the
computer (for a bit of reverb) and mix that
processed signal on the main outs with dry vocals
from CueMix DSP.
1. Live input (from mic, guitar, etc.)
enters the MOTU interface.
3. Mic signal is
‘patc hed thru’ back to
the audio interface
2. Mic signal goes immediately to the computer (dry,
with no effects processing).

ADJUSTING THE AUDIO I/O BUFFER
buffer is a small amount of computer memory
used to hold data. For audio interfaces like the
Trave l er, b uf fe rs ar e u sed for the process of
transferring audio data in and out of the computer.
The size of the buffers determines how much delay
you hear when monitoring live inputs through
your audio software: larger buffers produce more
delay; smaller buffers produce less.
Under Mac OS X, audio I/O buffer size is handled
by the host audio application (not the Traveler
Core Audio driver). Most audio software
applications provide an adjustable audio buffer
setting that lets you control the amount of delay
you’ll hear when monitoring live inputs or
processing them with software plug-ins. Below are
a few examples.
Figure 10-3: In Digit al Per form er and AudioDesk, choose Setup
menu> Configure Audio System> Configure Hardware Driver to open
the dialog shown above and access the Buffer Size setting. Refer to
your Digital Performer or AudioDesk manual for information about
the Host Buffer Multiplier setting.
A

enters the MOTU interface.
3. Mic signal is mixed with the
main outs, and you can control
the volume (relative to the rest
of the mix) with the mic’s fader
in CueMix Console.
Figure 10-2: This diagram shows the signal flow when using CueMix™ DSP no-latency monitoring. Notice that this method does not allow you
to process the live input with plug-ins in your audio software while it is being monitored. You can, however, add effects later — after recording
the live input as a disk track. CueMix™ DSP lets you hear what you are recording with no delay and no computer-based effects.
REDUCING MONITORING LATENCY
2. CueMix™ DSP immediately
patches the live mic signal directly
to the main outs (or other output),
completely bypassing the computer
(dry, with no effects processing).

How responsive the transport controls are in
AudioDesk, Digita l Performer or other audio
software
The buffer setting presents you with a trade-off
between the processing power of your computer
and the delay of live audio as it is being patched
through your software. If you reduce the size, you
reduce p atch thru latency, but significantly increase
the overall processing load on your computer,
leaving less CPU bandwidth for things like realtime effects processing. On the other hand, if you
increase the buffer size, you reduce the load on
your computer, freeing up bandwidth for effects,
mixing and other real-time operations.
Figure 10-6: When adjusting the buffer size to reduce monitoring
latency, watch the ‘processor’ meter in Digital Performer or
AudioDesk’s Performance Monitor. If you hear distortion, or if the
Perfo rmance meter is peaking, try raising the buffer size.
Figure 10-5: In Logic Audio, go to the Audio Driver preferences to
access the I/O buffer Size option shown above.
Lower latency versus higher CPU overhead
The buffer setting has a large impact on the
following things:
■
Patch thru latency
■
The load on your computer’s CPU
■
Possible distort ion at the smallest settings
76
If you are at a point in your recording project where
you are not currently working with live, patchedthru material (e.g. you’re not recording vocals), or
if you have a way of externally processing inputs,
choose a higher buffer size. Depending on your
computer’s CPU speed, you might find that settings
in the middle work best (256 to 1024).
Transport responsiveness
Buffer size also impacts how quickly your audio
software will respond when you begin playback,
although not by amounts that are very noticeable.
Lowering the buffer size will make your software
respond faster; raising the buffer size will make it a
little bit slower, but barely enough to notice.
REDUCING MONITORING LATENCY
Page 77
Effects processing and automated mixing
Reducing latency with the buffer size setting has
another benefit: it lets you route live inputs through
the real-time effects processing and mix
automation of your audio software.
CUEMIX DSP HARDWARE MONITORING
The Traveler has a more direct method of patching
audio through the system. This method is called
CueMix DSP . When enable d, CueMix activates
hardware patch-thru in the Traveler itself. CueMix
DSP has two important benefits:
■
First, it completely eliminates the patch thru
delay (reducing it to a small number of samples —
about the same amount as one of today’s digital
mixers).
■
Secondly, CueMix DSP imposes no strain on the
computer.
The trade-off, however, is that CueMix DSP
bypasses your host audio software. Instead, live
audio inputs are patched directly through to
outputs in the Traveler itself and are mixed with
disk tracks playing back from your audio software.
This means that you cannot apply plug-ins, mix
automation, or other real-time effects that your
audio software provides. But for inputs that don’t
need these types of features, CueMix DSP is the
way to go.
On the other hand, if you really need to use the
mixing and processing provided by your audio
software, you should not use CueMix DSP. Instead,
reduce latency with the buffer setting (as explained
earlier in this chapter).
TWO METHODS FOR CONTROLLING
CUEMIX DSP
There are two ways to control CueMix DSP:
■
With CueMix Console
■
From within your host audio software (if it
supports direct hardware monitoring)
Yo u c a n e ve n u s e b ot h methods simultaneously.
Using CueMix Console
If your host audio software does not support direct
hardware monitoring, you run CueMix Console
side-by-side with your audio software and manage
your monitor mix in CueMix Console.
CueMix Console allows you to create up to four
separate Traveler monitor mixes, or any other
desired routing configurations. These routings are
independent of your host audio software. For
complete details, see chapter 11, “CueMix
Console” (page 79).
Controlling CueMix DSP from your audio
software
Some audio applications allow you to control
CueMix DSP monitoring from within the
application (without the need to use CueMix
Console). In most cases, this support consists of
patching a Traveler input directly to an output
when you record-arm a track. Exactly how this is
handled depends on the application.
The following applications are among those that
support direct control over CueMix DSP:
■
Digital Performer
■
Aud ioD esk
CueMix DSP routings that are made via host
applications are made “under the hood”, which
means that you won’t se e t hem in CueMix Console.
However, CueMix DSP connections made inside
your host audio software dovetail with any other
mixes you’ve set up in CueMix Console. For
example, if your host application routes audio to an
output pair that is already being used in CueMix
Console for an entirely separate mix bus, both
audio streams will simply be merged to the output.

CueMix DSP in the Traveler hardware). For
example, if you record-enable a track called
guitar

ADVANTAGES OF CUEMIX MONITORING
CueMix Console provides several major
advantages over monitoring live inputs through
your host audio software:
CueMix has no buffer latency. Thanks to the
■
Trave l er ’s D SP chip, CueMix provides the same
throughput performance as a digital mixer.
■
CueMix imposes absolutely no processor drain
on the computer’s CPU.
CueMix routing can be maintained
■
independently of individual software applications
or projects.
■
CueMix routing can operate without the
computer, allowing the Traveler to operate as a
portable, stand-alone mixer.
CueMix Console does not provide effects
processing. For information about using your
audio software’s native plug-ins together with
CueMix, see chapter 10, “Reducing Monitoring
Latency” (page 73).
CUEMIX CONSOLE INSTALLATION
CueMix Console is installed with the rest of your
Trave l er so ftwa re .
CUEMIX CONSOLE BASIC OPERATION
The CueMix console is simple to operate, once you
understand these basic concepts.
Four mixes
CueMix provides four separate mixes: Mix1, Mix2,
Mix3 and Mix4. Each mix can have any number of
inputs mixed down to any Traveler output pair that
you choose. For example, Mix1 could go to the
headphones, Mix2 could go to the main outs, Mix3
could go to a piece of outboard gear connected to
analog outputs 7-8, etc.
Many inputs to one output pair
It might be useful to think of each mix as some
numbe r of inputs all mixed down to a stereo output
pair. CueMix Console lets you choose which inputs
to include in the mix, and it lets you specify the
level and pan for each input being fed into the mix.
Viewing one mix at a time
CueMix Console displays one mix at a time. To
select which mix you are viewing, click its tab at the
bottom of the window, as shown in Figure 11-1.
The mix name appears in the tab. Double-click the
name to change it.
Each mix is completely independent
Each mix has its own settings. Settings in one mix
will not affect another. For example, if an input is
used in one mix, it will still be available in other
mixes. In addition, inputs can have a different
volume, pan, mute and solo setting in each mix.
Some channel settings apply across all mixes
The settings at the top of the CueMix Console
window (above the channel section) apply to all
mixes. These settings include the preamp gain and
pad for the four mic inputs, and the +4/-10dB
reference level and +6dB software boost for analog
inputs 5-8.
Widening the CueMix Console window
To v ie w mo re input faders at once, drag the grow
box (Figure 11-1) to the right.
WORKING WITH A MIX

window, as shown in Figure 11-1. The mix name
appears in the tab.
Naming a mix
Double-click the mix name in the tab.
Input volume and pan
Use the input fader and pan knob (Figure 11-1) to
adjust these settings for the input in the mix. Again,
all settings within the gray-shaded channel strip
area belong to the mix currently being viewed.
Note that an input can have different settings in
different mixes.
To a dju st t he vo lume or panning for a stereo input

the fader or knob for either the left or right input.
Master mute
The master mute button (Figure 11-1) temporarily
disables (silences) the mix.
Master fader
The master fader (Figure 11-1) controls the overall
level of the mix (its volume on its stereo output).
Use the individual input faders to the left to control
individual input levels.
Output level meters
The OUT level meters show you the output for the
mix’s physical output, which may include audio
from your host audio software. The clip indicators
clear themselves after a few seconds.
Input section
The channel strips to the left of the master fader
represent each input in your Traveler. Use the input
scroll bar to view additional inputs.
Input mute/solo
To a dd a n i nput to a mix, or remove it, click its
MUTE button. To solo it, use its SOLO button. To
toggle these buttons for a stereo pair, hold down
the command key while clicking either channel.

PREAMP GAIN, PAD, REFERENCE LEVEL AND
+6DB BOOST
The preamp gain, pad, reference level and +6dB
boost settings at the very top of the CueMix
Console window (Figure 11-1) affect each input
globally, across all mixes and for audio being
routed to the computer. For example, if you add
6dB of boost, your host software will receive the
boost for that input as well.
Preamp gain
This setting (Figure 11-1) adjusts preamp gain, just
like the four trim knobs on the front panel of the
Tr a v e l e r.
Pad
These buttons (Figure 11-1) toggle the pad for each
mic input. Clicking these buttons is the same as
pushing the trim knobs on the front panel.
Boost
This setting (Figure 11-1) adds 6 dB of gain to the
input signal. This setting is applied globally for the
input.
+4/-10 reference level
Click the reference button to toggle between these
two standard reference levels. This setting is
applied globally for the input pair.
SAVING AND LOADING PRESETS
As explained earlier in “Save/Name Preset” on
page 53, the Traveler can store up to 16 presets in its
on-board memor y. A preset includes of all CueMix
DSP settings for all four mix busses, but it excludes
global settings like clock source and sample rate.
The Load Preset and Save Preset commands in the
CueMix Console File menu let you name, save and
load presets in the Traveler.
SAVING AND LOADING PRESETS TO/FROM
DISK
The Save and Load commands in the CueMix
Console File menu allow you to save Traveler
presets to and from your hard drive. This allows
you to save an unlimited number of Traveler
presets on disk. (Use the Load Preset and Save Preset commands to get presets from — and save
them to — the Traveler itself.) Click the Save
button to save the current configuration; click the
Load button to open an existing configuration that
you have previously saved on disk.
EDIT CHANNEL NAMES
Choose Edit Channel Names from the CueMix
Console File menu to open a window that lets you
customize the names of the Traveler’s inputs and
outputs. Your custom names appear in CueMix
Console (in the input name strip as shown in
Figure 11-1 on page 79) and in the input and
output menus of your host audio software. For
details, see “Edit Channel Names” on page 48.
TAL KB ACK AND LISTENBACK
CueMix Console provides Ta l k b a c k and Listenback
buttons. Talkback allows an engineer in the control
room to temporarily dim all audio and talk to
musicians in the live room. Conversely, Listenback
allows musicians to talk to the control room.
Hardware setup
Figure 11-2 below shows a typical hardware setup
for Talkback and Listenback. For Talkback, set up a
dedicated mic in your control room and connect it
to a mic input on your MOTU FireWire audio
interface. For Listenback, set up a dedicated
listenback mic in the live room for the musicians
and connect it to another mic input. For talkback
output, set up a headphone distribution amp or set
of speakers in the live room, and connect it to a pair
of outputs. For example, you might connect a
headphone distribution amp to analog outputs 7-8
on your MOTU Firewire audio interface, as
demonstrated below in Figure 11-2 on page 83.

for example, as a convenient way for you to record
the Traveler’s MIX1 monitor mix back into your
host audio software (for reference and archiving
purposes).
When the Mix1 return includes computer menu
item is checked, any audio being sent from your
audio software on the computer to the same output
as Mix1 will be included in the Mix1 return bus.
When it is uchecked, computer output is excluded.
This menu item is essentially a pre/post switch for
the computer audio insert to the stream of audio
going to Mix1’s Traveler out put pair (and also back
to the computer).
SHOW METER IN DOCK ICON
This CueMix Console File menu item, when
checked, causes the CueMix Console dock icon to
display a small level meter that mirrors the main
output meter for the current mix being displayed in
CueMix Console.

Controlling Talkback and Listenback volume
To c ont ro l t he vo lu me o f the Talkback and/or
Listenback mics, adjust their input fader in CueMix
Console. This fader controls the volume of the
input, regardless of which bus mix is being
displayed in the CueMix Console window. In other
words, once an input has been designated as a
Ta l kba ck or L is tenback input, its fader becomes
global for all CueMix buses.
MIX1 RETURN INCLUDES COMPUTER
The Mix1 return includes computer item in the
CueMix Console File menu refers to the Mix1 bus
that the Traveler driver provides as an input to host
audio software. This input source delivers the
output of CueMix DSP “MIX1” (the first mix bus of

PHONES MENU
The Phones menu allows you to choose what you
will hear on the headphone output, just like the
Phones setting the MOTU FireWire Audio
Console. However, this menu provides one extra
option that is exclusive to CueMix Console: Follow Active Mix. This menu item, w hen checked, causes
the headphone output to mirror the output of the
current mix being viewed in CueMix Console. For
example, if you are currently viewing Mix3 (the
Mix3 tab is active), the headphones will mirror the
Mix3 output (whatever it is assigned to).

CONTROL SURFACES MENU
CueMix Console can be controlled from an
automated control surface such as the Mackie
Control™. Use the commands in the Control Surfaces menu to enable and configure this feature.
Application follows control surface
When checked, the Application follows control
surface menu command makes the CueMix
Console window scroll to the channel you are
currently adjusting with the control surface, if the
channel is not visible when you begin adjusting it.
The same is true for the bus tabs: if you adjust a
control in a bus that is not currently being
displayed, CueMix Console will jump to the
appropriate tab to display the control you are
adjusting.
Mackie Control Surfaces
CueMix Console includes support for the following
control surface products:
■ Mackie Control™
■ Mackie HUI™
■ Mackie Baby HUI™
Use the sub-menu commands in the Mackie
Control Surfaces menu item to turn on and
configure control surface support, as described
briefly below.
Enabled
Check this menu item to turn on control surface
operation of CueMix Console. Uncheck it to turn
off control surface support.
Share surfaces with other applications
When the Share surfaces with other applications
menu command is checked, CueMix Console
releases the control surface when you switch to
another application. This allows you to control
your other software with the control surface. Here’s
a simple way to understand this mode: the control
surface will always control the front-most
application. Just bring the desired application to
the front (make it the active application), and your
control surface will control it. When you’d like to
make changes to CueMix Console from the control
surface, just bring CueMix Console to the front
(make it the active application).
When this menu item is unchecked, your control
surface will affect CueMix Console all the time,
even when CueMix Console is not the front-most
application. In addition, you will not be able to
control other host audio software with the control
surface at any time (because CueMix Console
retains control over it at all times). This mode is
useful when you do not need to use the control
surface with any other software.

Configure…
Choose this menu item to configure your control
surface product. Launch the on-line help for
specific, detailed instructions for configuring
CueMix Console for operation with your control
surface product.

Other HUI-compatible control surfaces
Any control surface that has the ability to emulate a
HUI should be compatible with CueMix Console.
Just add a Mackie HUI to Audi o MIDI Setup and
put the control surface hardware into HUI
emulation mode. Consult the manual for the
control surface for details about how put it into
HUI emulation mode.
Other control surface hardware products
If you install other control surface drivers written
for CueMix Console, they will appear as separate
menu items at the bottom of the Control Surfaces
menu, with the same sub-menu items described
above.
CUEMIX CONSOLE EXAMPLES
Figure 11-7 below shows some examples of how
you can use CueMix DSP:
■ Powe red speakers are connected to the Traveler
main outs. Any input can be routed directly to the
speakers.
■ Microphone input can be routed via CueMix
DSP to the effects processor for live outboard
processing during recording. The resulting signal
can be recorded into the computer either wet, dry
or both (via the effects processor return or the
direct mic input).
■ The ADAT optical connection provides 8
channels of 24-bit digital I/O to the digital mixer
(or 4 channels at 96kHz). Any device connected to
the Traveler can be routed to/from the mixer with
no latency. Conversely, any mixer channel can be
routed to any device connected to the Traveler with
no latency.

CHAPTER
12FireWire SMPTE Console
OVERVIEW
The Traveler can resolve to SMPTE time code,
without a dedicated synchronizer. It can also serve
as a SMPTE time code generator.
The FireWire SMPTE Console software provides a
complete set of tools to resolve to SMPTE, and to
generate SMPTE for striping, regenerating or
slaving other devices to the computer.
The Traveler provides a DSP-driven phase-lock
engine with sophisticated filtering that provides
fast lockup times and sub-frame accuracy.
Any analog input and output on the Traveler can be
used for time code (LTC) input and output,
respectively.
The Clock/Address menu provides the same global
Clock Source setting as in the MOTU FireWire
Audio Console (“Clock Source” on page 44), but it
includes additional information: each setting
shows both the clock and the address (time code or
sample location), separated by a forward slash ( / ).
For example, the word clock setting (Word Cl ock In / Internal) shows the clock source (Word C lock In)
followed by the address (Internal). Notice that only
the SMPTE setting supports SMPTE time code as
the reference for address. The digital clock sources
do not support the Traveler’s on-board SMPTE
time code sync.
Resolving to SMPTE time code
To r es o lve the Traveler to SMPTE time code,
choose the SMPTE / SMPTE setting in the Clock/
Address menu. This means that the system will use
SMPTE as the clock (time base) and SMPTE as the
The Generator sec tion
provides settings for striping
SMPTE time code.

SMPTE time code synchronization features.

address. For further details on the hardware
connections involved, see “Syncing to SMPTE time
code” on page 30.
Resolving to video
To resolve the Traveler to video, you need a
synchronizer such as a MIDI Timepiece AV or a
Digital Timepiece to feed word clock to the
Trave le r. I n t hi s sc enario, choose the Wor d C lo ck In
clock source setting in The MOTU FireWire Audio
Console. The Traveler uses word clock for the time
base and your host application resolves to MIDI
Time Code generated from the synchronizer. For
details, see “Syncing to video and/or SMPTE time
code using a synchronizer” on page 31.
FRAME RATE
This setting should be made to match the SMPTE
time code frame rate of the time code that the
system will be receiving. The Traveler can autodetect and switch to the incoming frame rate,
except that it cannot distinguish between 30 fps
and 29.97 fps time code. So if you are working with
either of these rates, make sure you choose the
correct rate from this menu. The Traveler driver
updates the frame rate setting in Digital Performer
and AudioDesk for you.
READER SECTION
The Reader section (on the left-hand side of the
window in Figure 12-1) provides settings for
synchronizing the Traveler to SMPTE time code.
Status lights
The four status lights (Tach, Clock, Address and
Freewheel) give you feedback as follows.
Clock
The Clock light glows continuously when the
Trave l er ha s successfully achieved lockup to an
external time base, such as SMPTE time code or
word clock.
Address
The Address light glows continuously when the
Trave l er ha s s uccessfully achieved lockup to
SMPTE time code.
Freewheel
The Freewheel light illuminates when the Traveler
is freewheeling address (time code), clock or both.
For details about Freewheeling, see “Freewheel
Address” and “Freewheel clock” below.
SMPTE source
Choose the analog input to which the SMPTE time
code source is connected. This is the input that the
Tr a ve l e r “ li s t e n s” to for time code.
Freewheel Address
Freewheeling occurs when there is a glitch or
drop-out in the incoming time code for some
reason. The Traveler can freewheel past the dropout and then resume lockup again as soon as it
receives readable time code. Choose the amount of
time you would like the Traveler to freewheel
before it gives up and stops altogether.
The Traveler cannot freewheel address without
clock. Therefore, the Freewheel Address setting will
always be lower than or equal to the Freewheel Clock setting, and both menus will update as
needed, depending on what you choose.
Ta c h
The Tach light blinks once per second when the
Trave l er ha s s uccessfully achieved lockup to
SMPTE time code and SMPTE frame locations are
being read.
88
Keep in mind that freewheeling causes the system
to keep going for as long as the duration you choose
from this menu, even when you stop time code
intentionally. Therefore, if you are starting and
stopping time code frequently (such as from the
transports of a video deck), shorter freewheel
times are better. On the other hand, if you are
FIREWIRE SMPTE CONSOLE
Page 89
doing a one-pass transfer from tape that has bad
time code, longer freewheel times will help you get
past the problems in the time code.
Tac h light
The Tach light blinks once per second when the
Trave l er is ge ne ra ti ng SMPTE time code.
The ‘Infinite’ freewheel setting
The Infinite freewheel setting in the Freewheel
Address menu causes the Traveler to freewheel
indefinitely, until it receives readable time code
again. To make it stop, click the Stop Freewheeling
button.
Freewheel clock
Freewheeling occurs when there is glitch or
drop-out in the incoming SMPTE time code for
some reason. The Traveler can freewheel past the
drop-out and then resume lockup again as soon as
it receives a stable, readable clock signal.
The Traveler cannot freewheel address without
clock. Therefore, the Freewheel Address setting will
always be lower than or equal to the Freewheel Clock setting, and both menus will update as
needed, depending on what you choose.
The ‘Infinite’ freewheel setting
The Infinite freewheel setting in the Freewheel
Clock menu causes the Traveler to freewheel
indefinitely, until it receives readable time code
again. To make it stop, click the Stop Freewheeling
button.
Stop Freewheeling
The Stop Freewheeling button stops the system if it
is currently freewheeling.

CHAPTER
13Troubleshooting
Things seems like they are working fine, but the
Traveler t he n ju st drops off line, and the computer
can’t see it anymore on the FireWire bus.
This is a common symptom when the problem is
that the Traveler is not getting enough power.
Check the power source for the Traveler. Make sure
that the power connection meets the requirements
outlined in “Power options” on page 20.
Sample accurate sync in AudioDesk and Digital
Per former
When you first use sample accurate sync, be sure to
go to the Receive Sync dialog in Digital Performer
or AudioDesk and switch from “MTC” to “Sampleaccurate.”
Can’t authenticate AudioDesk
When installing software off the CD-ROM, the OK
button does not become active until you have
entered in your name and a valid keycode. Your
name must contain at least 3 characters, and you
must enter the keycode exactly as it appears in your
AudioDesk manual (on the inside of the back
cover). If you continue to have difficulties, try
repairing Mac OS X disk permissions using Disk Utilit y.
No input on an ADAT tape deck
If you are having trouble recording on your ADAT
tape deck from the Traveler, check the Digital input
setting. After power cycling, tape decks often come
up configured to record from their analog inputs.
Yo u w on 't b e able to record from the Traveler to a
tape deck until it is switched to digital input. Tip:
configure this in ClockWorks or AudioDesk if you
want your decks to come up in the right mode
when power cycled.
Clicks and pops under word clock sync
Many problems result from incorrect word
clocking. It is essential that all digital devices in the
system be word locked. Consult “Making sync
connections” on page 25 for detailed information
on how to word clock your gear. Whenever there is
any weird noise or distortion, suspect incorrect
word lock.
Clicks and pops under ADAT Sync
Sometimes, the ADAT sync cable seems to be
plugged into the Traveler, and it partially works.
But it isn’t really all the way in. This can cause clicks
when slaved to ADAT 9-pin. Make sure the ADAT
Sync cable plug is really seated firmly.
Clicks and pops due to hard drive problems
If you have checked your clock settings and you are
still getting clicks and pops in your audio, you may
have a drive related problem. Set your Clock
Source to Inter nal and try recording just using the
analog inputs and outputs of the Traveler. If you
encounter the same artifacts you may want try
using another drive in your computer. Clicks and
pops can also occur when the drive is severely
fragmented, the disk drivers are outdated, or if you
are using a SCSI accelerator that is not optimally
configured for working with audio.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the Traveler while recording or playing back audio.
Doing so may cause a brief glitch in the audio.
No optical inputs or outputs are available in host
audio application
Check to make sure you have the desired optical
inputs and/or outputs enabled in the MOTU
FireWire Audio Console.

Monitoring - How to monitor inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the Traveler’s hardware-based CueMix DSP
monitoring feature. Please see chapter 10,
“Reducing Monitoring Latency” (page 73).
