Introduction
Overview
Thank you for choosing the TASCAM FW-1804. We have
designed the FW-1804 to be an ideal audio/MIDI interface
for your computer-based digital audio workstation system.
Its integrated design incorporates a high-resolution professional multi-channel audio interface and integrated zerolatency input monitor mixer and a 2 x 4 MIDI interface.
Please take some time to look through this owner's manual
and familiarize yourself with the FW-1804's features and
operation. We suggest you pay particular attention to the
operational notes for your software application(s) of choice.
You may also want to refer to your software's documentation in many cases, for a clear understanding of how to configure device drivers. Your experience with the FW-1804
will be greatly enhanced by a good working knowledge of
your audio software.
Features
The audio input section is fully 24-bit and can accommodate sample rates of up to 96 kHz. It is capable of inputting
up to eighteen simultaneous channels of audio (eight analog, eight ADAT digital and two S/PDIF digital) to your
computer. It features eight analog inputs, four with professional quality microphone preamps and switchable phantom
power, as well as eight line inputs and four analog channel
inserts. Digital inputs are available in an S/PDIF coaxial
configuration and an ADAT optical configuration.
The output section offers two balanced line level analog
outputs. A stereo S/PDIF coaxial digital output and eight
channel ADAT optical output are also featured.
The FW-1804 is supported under Windows XP and
Windows 2000, Mac OS X 10.2.8 (Jaguar) or later and Mac
OS 9.2.2 or later. In addition, your computer must be fitted
with a 6-pin IEEE 1394 (FireWire
TM
) interface.
NOTE
Some manufacturers may use a different nomenclature to
refer to their FireWireTMconnections, such as Sony's
"i.LINK", or simply "1394".
The FW-1804 comes with a high-quality 6-pin to 6-pin
interface cable. We strongly suggest you use this cable, or
one of equal quality, for optimum audio performance. We
always recommend the use of a 6-pin IEEE 1394 connector
(not the 4-pin type) on your computer.
The FW-1804 is supplied with a 2 m (6-foot) cable. If you
wish to use a longer cable, the length should not be more
than 4 m (13 feet) and the cable should be the best possible
quality available to avoid data loss, which results in audio
dropouts.
CAUTION
• We strongly suggest that although a "daisy-chain" connection is provided, that the FW-1804 is the only unit
connected to the FireWire port.
• Always perform all FireWire connections and disconnections with the power to both the FW-1804 and the computer turned off. If connections are made or broken with
power to the FW-1804 or computer turned on, this may
result in your computer crashing, or "freezing" and possible loss of data.
• When turning the power of the FW-1804 on and off
when it is connected to the computer, turn on the power
before launching the DAW software, and quit the software before turning off the FW-1804.
System Requirements
The FW-1804 is supported under Windows XP and
Windows 2000. The FW-1804 is not supported under
Windows 98 or Windows ME.
In the case of Windows 2000, you must be running SP3 or
SP4 and then use the supplied installer which includes the
Hotfix. Windows 2000 SP5 includes the Hotfix, so the FW1804 driver installer only may be used. For Windows XP,
you must be running SP1 and then use the supplied installer
which includes the Hotfix. Windows XP SP2 includes the
Hotfix, so the FW-1804 driver installer only may be used.
On the Mac, the FW-1804 is supported under Mac OS X
version 10.2.8 or later and Mac OS 9.2.2. Earlier versions
of Macintosh operating systems are not supported.

TASCAM FW-1804 7
Parts of the FW-1804
Front Panel
The FW-1804 front panel is conveniently grouped into logical areas.
Input Section
TRIM controls
Analog level controls for the input level of the mic (XLR)
inputs 1 through 4, and line inputs 1 through 8. Their function is the same regardless of the monitor mode selected.
Note that the best signal-to-noise ratios are achieved by
maximizing the level of analog inputs at the A/D converters. For the mic and line inputs of the FW-1804, the TRIM
controls provide the means for optimizing these levels.
OL indicators
The OL indicators light to indicate a signal peaking at
–2.5dBFS or higher by default (this level is adjustable
between 0.0 dBFS and 5.0 dBFS, in 0.5 dB increments,
using the FW-1804's software Control Panel). When one of
these indicators lights, it indicates an overloaded input—
reduce the level of the input to the channel until the indicator goes out.
SIGNAL indicators
The SIGNAL indicators light to indicate the presence of an
audio signal at the corresponding analog input. These indicators light when the signal level is –42 dBFS or higher.
These indicators and the OL indicators indicate signal levels to the eight analog inputs regardless of the monitor
mode selected.
PHANTOM switch
Use this switch to enable phantom power for the microphone jacks.
CAUTION
Microphones should not be connected to or disconnected
from the FW-1804 with phantom power switched on.
Unbalanced dynamic microphones should never be connected to phantom-powered connectors.
GUITAR/LINE switch
Affects LINE IN 8 only. When this is set to GUITAR, the
input impedance then matches that of an electric guitar or
passive bass. For all other instruments, leave this in the
LINE position.
Indicators
ADAT indicator
This indicator lights when a valid clock signal in ADAT
format is received.
D IN indicator
This indicator lights when a valid clock signal in S/PDIF or
TOSLINK format is received.
CLOCK indicator
This indicator lights when the internal clock is locked to the
selected sampling frequency.
FireWire indicator
This indicator lights when a valid IEEE 1394 (FireWire)
connection is made between the FW-1804 and the host
computer.
MIDI IN and OUT indicators
These light momentarily when MIDI activity is detected on
the appropriate port(s). These indicators function independently of the monitor mode.
8 TASCAM FW-1804
Parts of the FW-1804
Monitoring and Phones
COMPUTER / INPUTS / BOTH keys
These keys select the source of the signal being sent to the
balanced stereo analog outputs.
COMPUTER: Only the audio from the host computer is
monitored. This can be useful if you're doing a mixdown
of your DAW tracks and want to mute the monitor mixer
without losing its settings.
INPUTS: Only the audio from the FW-1804's analog,
ADAT and S/PDIF inputs is monitored. This can be useful for setting up live inputs or tracking into your DAW.
BOTH: The audio signals from the host DAW and the FW-
1804's inputs are monitored.
MONITOR control
This analog control affects the level of the signal sent from
the balanced 1/4" STEREO OUT (BAL) outputs.
PHONES control
This analog control affects the level of the signal sent from
the stereo PHONES jack.
PHONES jack
Headphone level output from a stereo 1/4" jack.
POWER Switch
Make sure the switch is off when making the power connection.
NOTE
Wait more than five seconds before you turn on the FW1804 just after you turned it off. Otherwise, the FW1804 may not be started up normally.
WARNING
The FW-1804 outputs produce a "thump" when the
power is turned on.
To avoid any damage to hearing or equipment, turn the
volume of the monitoring system down, or make sure it
is turned off, and do not wear headphones connected to
the FW-1804 when powering the unit on or off.
TASCAM FW-1804 9
Parts of the FW-1804
DC IN jack
Connect only the power adapter supplied with your FW1804 to this jack.
Make sure the POWER switch is off when making the
power connection.
MIDI IN/OUT connectors
Two MIDI IN and four MIDI OUT connectors allow you to
hook up MIDI controllers, etc. as well as external tone generator modules, etc.
MIC/LINE jacks (1-4)
XLR-TRS combo jacks to input microphones or line level
sources. The XLR connectors (1: ground, 2: hot, 3: cold)
are connected to internal microphone pre-amplifiers. The
TRS (tip: hot, ring: cold, sleeve: ground) jacks are balanced
line level (+11 dBu) analog inputs. These use concentric
jacks so only one source, a mic or a line source, can be connected.
CAUTION
Microphones should not be connected to or disconnected
from the FW-1804 with phantom power switched on.
Unbalanced dynamic microphones and some ribbon
microphones should never be connected to phantompowered connectors. Check with your microphone manufacturer if you are unsure.
INSERT jacks (1-4)
Individual channel inserts. These are 1/4" TRS (tip: send,
ring: receive, sleeve: ground) jacks which allow you to
insert an external processor, such as an analog compressor,
into the signal chain for inputs 1 to 4 (mic or line). The
insert point is placed between the input (after the mic/line
trim) and the analog-to-digital converter. A standard insert
"Y" cable with a TRS plug is required. Check with your
music retailer.
LINE IN jacks (5-8)
Balanced line level (+4 dBu) 1/4" TRS (tip: hot, ring: cold,
sleeve: ground) analog inputs.
STEREO OUT (BAL) L & R jacks
Two balanced +4 dBU line-level outputs on 1/4" TRS jacks
(tip: hot, ring: cold, sleeve: ground).
WORD IN connector
Coaxial BNC connector for input of external Word Clock
signal from another device. This input is 75 ohm terminated.
WORD OUT connector
Coaxial BNC connector for output of the FW-1804's Word
Clock signal to another device.
ADAT/OPTICAL IN/OUT connectors
Fiber-optic input/output to accommodate eight-channel
ADAT format or two-channel S/PDIF in TOSLINK format.
COAXIAL IN/OUT connectors
S/PDIF coaxial digital input and output using RCA (pin)
connectors.
FireWire ports
Use one of these ports to connect the FW-1804 to the host
computer, providing audio communication. Either port may
be used to connect the FW-1804 to your computer.
FOOT SW jack
Accommodates a standard momentary foot switch through
a 1/4" jack. The function of this jack is assigned in the software control panel.
Rear Panel
10 TASCAM FW-1804
Monitor Mixing
Setting and Checking Clock Rates
The FW-1804's audio clock rate and source are checked or
changed from the software Control Panel.
Expected Sample Rate
If a digital input is selected as the clock source and it does
not have a usable clock signal, the CLOCK indicator flashes to indicate a problem, and the unit switches to its own
internal clock and waits for a valid clock signal. If the sample rate is off by 3% or more, the FW-1804 switches to the
internal clock.
Monitor Mixing
The FW-1804 has a hardware monitor mixer which is controlled by a software mixer window accessed from the software Control Panel. The primary benefit of this is to provide a means of monitoring your audio inputs in a zerolatency environment.
By using the monitor mixer to monitor the audio at the
inputs along with the audio return from your DAW application, it is possible to overdub tracks to your DAW software
with none of the audio processing delays inherent in DAW
applications.
Monitoring Setups
The source of the signal being sent to the balanced stereo
analog outputs is dependent on which of the three keys is
selected: COMPUTER, INPUTS or BOTH.
COMPUTER key
Only the audio from the host computer is monitored. This
can be useful if you're doing a mixdown of your DAW
tracks and want to mute the monitor mixer without losing
its settings.
INPUTS key
Only the audio from the FW-1804's analog, ADAT and
S/PDIF inputs is monitored. This can be useful for setting
up live inputs or tracking into your DAW.
BOTH key
The audio signals from the host DAW and the FW-1804's
inputs are monitored.
• The default setting is BOTH.
Making Mixer Settings
Once the monitor setup has been made, it is possible to use
the software mixer interface to set the levels and pan position. Click the Show Mixer button on the Settings tab of
the Control Panel.
The following screen will appear:
Setting the master fader to 0 dB (unity gain)
Hold [Shift] and click the master fader.
Setting a channel's monitor level to 0 dB (unity gain)
Hold [Shift] and click the channel fader.
NOTE
It is important to understand that when using the monitor
mixer, the FW-1804's software mixer interface is controlling the monitor levels of the FW-1804's input sources.
While you will still hear the audio returns from your DAW,
moving the faders in the FW-1804's software monitor mixer
has no effect on your DAW's internal mixer.
Another important point to note is that monitor mixer's
faders do not affect the levels of the inputs sent to your
DAW. The levels to the DAW inputs from analog inputs 1
through 8 are controlled solely by their respective TRIM
controls. The digital inputs are passed to your DAW application at unity gain; their level must be regulated at the digital source.
TASCAM FW-1804 11
Monitor Mixing
Setting Input Levels
The FW-1804 can be very useful for recording live tracks
into a DAW application. Here's a typical scenario for
recording and overdubbing using the FW-1804:
1 Connect your analog and/or digital source(s) to the FW-
1804's inputs.
2 Access the monitor mixer's software interface.
3 Press the INPUTS key to monitor the inputs without
hearing your existing DAW tracks.
4 Adjust the channel's TRIM control (if it is an analog
input) or the digital source (if it is a digital input) until
the input meter in your DAW shows a level that is hot,
but not clipping.
5 Repeat this procedure for all active input channels.
Once you're done setting up levels, you can return to
COMPUTER monitor mode and begin recording.
12 TASCAM FW-1804
Control Panel
The FW-1804's Control Panel is where you can display and
adjust settings which determine how the FW-1804 communicates with your computer and other external devices. To
open the Control Panel:
Windows: Click on Start -> Control Panel and selecting
the FW-1804 Control Panel icon.
OS X: The FW-1804 Manager can be found in
Applications.
OS 9: The FW-1804 Control Panel can be found in
Control Panels.
There are three tabs on the Control Panel: Settings,
Routing, and Quick Start. Under Mac OS X, Core Audio
tab is in place of Quick Start.
Settings Tab
This is where you make the basic settings to configure the
FW-1804.
Footswitch Message
This is where you select how the FW-1804's footswitch
command is interpreted by the host software application.
You can choose between FW-1804 Native or Mackie
Control emulation protocol.
Clock Source
This is where you can select the digital clock source.
Sample Rate
This is where you select the expected sample rate to the
FW-1804's digital inputs and the internal sampling frequency.
Audio Latency
This setting is for selecting the buffer size of the FW-1804's
audio performance. The FW-1804's driver temporarily
stores input and output audio samples in buffers. Larger
buffer sizes will produce higher latencies but will result in
greater system stability, and protection against other system
activities causing clicks, pops and other audio artifacts.
Some experimentation is always required to find the best
balance between latency and stability.
OVR Threshold
This setting determines the level at which the FW-1804's
OL indicators register an "over," or clipping level. It can be
varied between 0.0 and –5.0 dBFS, in .5 dBFS increments.
Compensate for Converter delays (WDM)
This setting (Windows only) allows WDM drivers to compensate for converter delays.
Routing Tab
Optical Output Source
This menu selects the source of the audio output appearing
at the FW-1804's ADAT optical outputs. The selections are:
ADAT 1:8 - The audio output is determined within your
DAW application software. Audio which has been routed to
the FW-1804's ADAT outputs within your DAW will
appear at the ADAT lightpipe output.
Duplicate of Coax Output (TOS) - The audio output is the
same as that being sent to the FW-1804's analog outputs L
and R , and is sent out the lightpipe in two-channel
TOSLINK protocol. This can be useful for sending a twotrack mix to a mixdown recorder equipped with an optical
two channel input.
Analog Inputs 1:8 - The signal present at the eight analog
inputs is routed directly to the ADAT outputs. This is useful in the event you have an analog source that needs to be
input to another device that only has ADAT inputs.
Coax Output Source
This menu selects the source of the audio output appearing
at the FW-1804's coaxial digital output. The selections are:
TASCAM FW-1804 13
Control Panel
SPDIF 1:2 - The audio output is determined within your
DAW application software. The FW-1804's S/PDIF outputs
are seen as separate outputs within your DAW application.
With this setting, audio which has been routed to these outputs appears at the FW-1804's two-channel digital outputs.
Monitor Mix 1:2 - The audio output is identical to that
being sent to the FW-1804's STEREO OUT. This is useful
if, for example, you wish to send the stereo mix you are
monitoring to a two channel digital mixdown recorder.
Note that the MONITOR control does not affect the coaxial
output in this case.
SPDIF Input Routing
This menu selects the source of the audio input appearing at
the FW-1804's two-channel digital (D IN) inputs. The
selections are:
COAX to SPDIF 1:2 - The digital audio signal being input
to the FW-1804's coaxial digital input is routed to the twochannel digital (D IN) inputs.
Optical to SPDIF 1:2 - A two-channel digital audio signal
in TOSLINK format, being input to the FW-1804's optical
digital input, is routed to the two-channel digital (D IN)
inputs. (Note that the ADAT inputs will not be available to
your DAW application if you use the optical input connector in TOSLINK mode.)
Quick Start Tab (Windows only)
This allows you to specify a set of channels which will
always stream when using WDM/KS Driver Mode in
SONAR.
This, for example, speeds up the start of a playback or
record operation in SONAR, especially when there are a lot
of channels enabled. If there is a hesitation after pressing
PLAY or RECORD before the operation begins, try
enabling this feature.
To use it, check the channels that you will be using in your
WDM audio app. When the channels selected in the Quick
Start tab match the channels actually used by your application, the FW-1804 will not have to re-sync when the application begins to use those channels. This has shown to be
much faster, and less prone to produce an "audio engine
stop" message.
Core Audio Tab (Mac OS X only)
In OS X, you can specify how the FW-1804 should appear
to the operating system:
The options available are as follows:
An 18-Input/12-Output Sound Device
All input and output channels are used. The S/PDIF input
channels become channels 17 and 18, and the S/PDIF output channels become two output channels in addition to the
ADAT and monitor outputs.
An 8-Channel Sound Device
Select either the analog input channels or the ADAT input
channels. The outputs are the analog monitor outputs or the
ADAT outputs. Note that the ADAT output level is not
controlled by the front panel MONITOR control.
A 2-Channel (Stereo) Sound Device
Select any pair (1-2, 3-4 etc.) of inputs as the input pair.
Select any pair of outputs as the output pair. Note that only
the stereo analog outputs are controlled by the front panel
MONITOR control.
TIP
In order to optimize the load on your CPU, you should configure the FW-1804 for your situation. If you are making a
live stereo recording using the FW-1804, there is little point
in configuring an 18-in/12-out device, for example.

Is the channel trim control adjusted correctly?
If your audio source is a condenser microphone:
Do you have phantom power enabled?
If your audio source is a digital input:
Do you have a valid digital source connected?
Are the correct clock settings selected?
If your audio source is your DAW application:
Do you have the correct outputs selected within the host
application?
If you're running Windows 2000 or Windows XP:
Does the FW-1804 appear as an audio device in Device
Manager? Is the Device Manager free of yellow marks?
My audio is distorted.
Is your input level too hot (OL indicators lighting)?
My audio has clicks and pops.
Do you have the correct clock source selected?
Is the latency set too low?
