5. First Usage – Quick Start
5.1 Connectors – Controls – Display
The front of the Fireface UFX+ features four combined instrument / microphone inputs, two
stereo headphone outputs, three rotary encoders with push functionality, a graphical colour
display, one MIDI input and output, a USB connector for DURec, and several status LEDs.
The Neutrik combo sockets of the four
Mic/Line inputs provide XLR and 6.3 mm /
1/4" TRS connection. They have LEDs for
Signal (SIG), phantom power (48V) and
activated TRS input. The latter is high
impedance (1 MOhm) and also serves as
instrument input.
The analog outputs 9 to 12 feed the headphones outputs Phones 1 and Phones 2. These low
impedance outputs of highest quality are able to drive headphones at higher levels undistorted,
no matter if low or high impedance headphones are used.
MIDI 2 I/O. Two 5-pin DIN connectors provide the second MIDI input and output.
Memory. Connector for USB stick or USB hard drive. Offers direct Recording to / Playback from
the external memory device.
State LEDs Sync. WC, AES, ADAT1, ADAT2, MADI. Indicate a valid input signal separately for
each digital input. Additionally, RME's exclusive SyncCheck indicates if one of these inputs is
locked, but not synchronous to the others, in which case the LED will flash. See also chapter
8.7 / 14.2, Clock Modes - Synchronization.
State LEDs MIDI. Indicate separately for input and output if MIDI data is received or transmitted. HOST lights up when the connection to the computer is successful. Thunderbolt, USB 3
and USB 2 are indicated by different colours. The LED will not turn on when connection has not
been initialised or interrupted (error, cable not connected etc.).
When the Global Level Meter screen is shown, the rotary encoder Volume sets the monitoring
volume of Main Out directly at the device. Pushing the button will change between Global Meter
screen and the last used menu entry.
When the Global Level Meter screen is shown, volume of Phones 1 and Phones 2 is set by
encoders 1 and 2 directly. Pushing these toggles the meter screen between standard view
(Analog, AES, ADAT, FX) and MADI view.
The four keys, the two encoders 1
and 2, the high-resolution and clear
colour display, and a well thoughtout menu structure enable the user
to quickly change and configure the
device’s settings completely without
a computer. Help notes and clear
markers in the display guide the
user through all functions.

The rear panel of the Fireface UFX+ features eight more analog inputs and outputs, the power
socket, and all digital inputs and outputs:
Balanced Line Level Inputs. 8 balanced analog inputs via 6.3 mm stereo TRS connectors.
Balanced Line Level Outputs. 8 balanced analog outputs, six via 6.3 mm stereo TRS, two via
XLR.
AES/EBU I/O. XLR. The Fireface UFX+ accepts
the commonly used digital audio formats, SPDIF
as well as AES/EBU.
MADI I/O optical: Standard optical MADI ports
(SC).
Word Clock I/O. BNC. In the Settings dialog,
Input Options, this input can be set to be terminated with 75 Ohms internally.
MADI I/O coaxial: The BNC sockets can be switched individually between word and MADI I/O
functionality via the Settings dialog.
ADAT1 I/O. TOSLINK. Standard ADAT optical port, 8 channels.
ADAT2 I/O. TOSLINK. Standard ADAT optical port, 8 channels. Can also be used as optical
SPDIF input and output, if set up accordingly in the Settings dialog.
Remote. Connector for the optional Advanced Remote Control USB (ARC USB) when the
UFX+ is used in stand-alone and Class Compliant mode. This port can also be used alternatively to the connection of the ARC USB to the computer.
Thunderbolt. Thunderbolt port for connection to any compatible computer.
USB 3.0. USB socket for connection to the computer. Compatible to USB 2.0 (no MADI record
and playback channels then, but all other 30 I/Os).
MIDI I/O 1. Two 5-pin DIN connectors provide the first MIDI input and output.
Hook. Secure any loose cable by feeding it through the hook first.
IEC receptacle for mains power
connection. The internal hiperformance switch mode power
supply operates in the range of 100V
to 240V AC at highest power
efficiency. It is short-circuit-proof, has
an integrated line filter, is fully
regulated against voltage
fluctuations, suppresses mains interference, and offers hum-free operation.

5.2 Quick Start
After the driver installation (chapter 6 / 13) connect the TRS jacks or the XLR inputs with the
analog signal source. The input sensitivity of the rear inputs can be changed in TotalMix (Input
Channel Settings, LoGain / +4 dBu and Gain), assuring the highest signal to noise ratio will be
achieved. Also try to achieve an optimum input level by adjusting the source itself. Raise the
source’s output level until the peak level meters in TotalMix reach about –3 dB.
The signal level of the front inputs can also be optimized directly at the
Fireface. The key MIC/GAIN gives direct access to this setting, which is
then controlled by the encoders 1 and 2. A two-colour LED beside the
sockets signals overload by a colour change from green to red.
The digital outputs of the Fireface UFX+ provide AES/EBU (SPDIF
compatible) and ADAT optical signals at the corresponding ports.
On the analog playback side (the DA side), a coarse adjustment of the
analog output level at the rear jacks is again available in TotalMix
(Output Channel Settings, Level), or the Channel Settings directly at
the device. The big Volume encoder controls the Main Out volume
(default: Analog 1/2).
The output signal of channels 9/10 and 11/12, Phones 1 and 2, can be
controlled directly from front by the small encoders 1 and 2.
The Fireface UFX+ can store and load its current state in 6 different
memory slots, called Setups. With this, the Fireface UFX+ can be
used stand-alone after setting it up accordingly, replacing lots of
dedicated devices (see chapter 24).
In online mode some settings are greyed out, as these should be changed only at the computer,
in the Settings dialog or in TotalMix FX. These include the choice of sample rate and the mix
settings.
The factory setting for the Interface Mode, Auto, makes sure that any
connected computer connection is recognized automatically.
Thunderbolt, USB 3, USB 2 and Class Compliant will usually work
without any further user interaction. In case of problems the current
interface mode can be set manually to a fixed one. This is done under
SETUP/REV, Options, Hardware/Diagnosis, Interface Mode.

6. Hardware, Driver and Firmware Installation
6.1 Hardware and Driver Installation
To simplify installation it is recommended to first install the drivers before the unit is connected
to the computer. But it will also work the other way round.
Insert the RME Driver CD into your CD-ROM drive. The driver installer is located in the directory
\Thunderbolt for Thunderbolt
\MADIface_USB for USB 3 and USB 2.0 (NOT Fireface_USB)
Start rmeinstaller.exe and follow the instructions of the installer. After installation connect com-
puter and UFX+ using a USB 2, USB 3.0 or Thunderbolt cable. Windows detects the new hardware as Fireface UFX+ and installs the drivers automatically.
After a reboot, the icons of TotalMix FX and Settings dialog appear
in the notification area.
Driver Updates do not require to remove the existing drivers. Simply install the new driver over
the existing one.
6.2 De-Installing the Drivers
A de-installation of the driver files is not necessary – and not supported by Windows anyway.
Thanks to full Plug & Play support, the driver files will not be loaded after the hardware has
been removed. If desired these files can then be deleted manually.
Unfortunately Windows Plug & Play methods do not cover the additional autorun entries of TotalMix, the Settings dialog, and the registration of the ASIO driver. Those entries can be removed from the registry through a software de-installation request. This request can be found
(like all de-installation entries) in Control Panel, Software. Click on the entry 'RME Thunderbolt'
or 'RME MADIface'.
6.3 Firmware Update
The Flash Update Tool updates the firmware of the Fireface UFX+ to the latest version. It requires an already installed driver.
Start the program fut_tb.exe (Thunderbolt) or fut_mfusb.exe (USB). The Flash Update Tool
displays the current revision of the Fireface firmware, and whether it needs an update or not. If
so, then simply press the 'Update' button. A progress bar will indicate when the flash process is
finished (Verify Ok).
After the update the unit needs to be reset. This is done by powering down the unit for a few
seconds. A reboot of the computer is not necessary.
When the update unexpectedly fails (status: failure), the unit's Safety BIOS will be used from
the next boot on, the unit stays fully functional. The flash process should then be tried again.

User's Guide Fireface UFX+ © RME
7. Configuring the Fireface
7.1 Settings dialog – Main Tab
Configuration of the Fireface UFX+ is done via its own settings dialog. The panel Settings can
be opened by clicking on the fire or hammer symbol in the Task Bar's system tray.
The mixer of the Fireface UFX+, TotalMix FX, can be opened by
clicking on the DSP FX symbol in the Task Bar's system tray
The hardware of the Fireface UFX+ offers a number of helpful, well thought-of practical functions and options which affect how the card operates - it can be configured to suit many different requirements. The 'Settings' dialog includes options for:
• Latency
• Operation of the DSP
• Configuration of the digital I/Os
• Current sample rate
• Synchronization behaviour
• State of input and output
Any changes made in the Settings
dialog are applied immediately confirmation (e.g. by clicking on OK or
exiting the dialog) is not required.
However, settings should not be
changed during playback or record if it
can be avoided, as this can cause
unwanted noises. Also, please note that
even in 'Stop' mode, several programs
keep the recording and playback
devices open, which means that any
new settings might not be applied
immediately.
The tab About includes information
about the current driver and firmware
version of the Fireface. The USB driver
shows two options there (the
Thunderbolt driver presents these on an
additional Global tab):
Lock Registry
Default: off. Checking this option brings
up a dialog to enter a password.
Changes in the Settings dialog are no
longer written to the registry. As the
settings are always loaded from the
registry when starting the computer, this
method provides an easy way to define
an initial state of the Fireface UFX+.
Enable MMCSS for ASIO activates support with higher priority for the ASIO driver. Note: At this
time, activating this option seems to be useful only with the latest Cubase/Nuendo at higher
load. With other software this option can decrease performance. The change becomes active
after an ASIO reset. Therefore it is easy to quickly check which setting works better.
User's Guide Fireface UFX+ © RME
15
Buffer Size
The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM
data, as well as affecting system stability (see chapter 9.1).
USB Diagnosis and Errors does not refer to buffer errors, but USB transmission errors. The
display will be reset on any start of a playback/record. More information can be found in chapter
39.3.
Input Options
Word Clock In Termination
Checking this option terminates the word clock input internally with 75 Ohms.
Optical 2 In
Operates as second ADAT input (default). Selecting AES/SPDIF will route the optical input sig-
nal to the AES-Receiver. This mode disables the AES input via XLR.
DSP – EQ+D for Record
Switches EQ and Dynamics of all input channels into the recording path. In case Loopback has
been activated the EQ and Dynamics of the Output channel are within the recording path. See
also chapter 27.6.
MADI Input
Options: Optical - default. Coaxial - the BNC word clock input can be used as coaxial MADI
input. AutoSelect - the UFX+ scans both inputs for a valid MADI signal and activates one as
soon as a MADI signal is found. Split – uses both inputs with 32 channels each.
TMS activates the transmission of Channel Status data and Track Marker information on AES,
SPDIF and MADI inputs. In case these information are not required the feature should be turned off.
Iso(chronous) Streaming (USB 3 only)
The UFX+ uses a special transmission mode with error correction in record mode. In case the
default mode does not work Isochronous Streaming can be tried. This is the standard’s native
mode for audio transmission and should work with any USB 3 controller. See also chapter 39.3.
Output Options
AES Format
The AES output signal can have the Channel Status Professional or Consumer (SPDIF). This
setting is also valid when ADAT2 has been set as AES/SPDIF output. For further details please
refer to chapter 21.2.
Optical 2 Out
This optical TOSLINK output can operate as ADAT or AES/SPDIF output.
MADI Format
Defines the format of the MADI output signal. MADI can be a 56 or 64 channel signal.
MADI Frame
Sample rates higher than 48 kHz can be transmitted using the normal 48K Frame, or using a
native 96K Frame at the card's output.
MADI Output
Options: Optical - default. Mirror - the BNC word clock output can be used as coaxial MADI
output carrying the same signal as the optical output. Split - uses both outputs with 32 channels
each.
16
User's Guide Fireface UFX+ © RME
WDM Devices
Allows to freely set which I/Os are available as WDM devices, if these are stereo or multichannel devices (up to 8 channels), and if one or multiple of the currently active WDM devices
should have the Speaker property. More details are found in chapter 7.2.
Clock Mode
Word Clock – Single Speed
The word clock output signal usually
equals the current sample rate.
Selecting Single Speed causes the
output signal to always stay within the
range of 32 kHz to 48 kHz. So at 96 kHz
and 192 kHz sample rate, the output
word clock is 48 kHz.
Sample Rate
Sets the currently used sample rate.
Offers a central and comfortable way of
configuring the sample rate of all WDM
devices to the same value, as since
Vista the audio software is no longer
allowed to set the sample rate.
However, an ASIO program can still set
the sample rate by itself. During
record/playback the selection is greyed
out, so no change is possible.
Clock Source
The unit can be configured to use its
own clock (Internal = Master), or one of
the input signals (Word, AES, ADAT1,
ADAT2, MADI optical, MADI coaxial). If
the selected source isn't available (Input
Status No Lock), the unit will change to
the next available one (AutoSync). If
none is available then the internal clock
is used. The current clock source is
displayed to the right.
Pitch (Thunderbolt only)
More information on Pitch is available in chapter 7.4.
Input Status
Indicates for each input (Word, AES, ADAT1, ADAT2, MADI optical, MADI coaxial) whether
there is a valid signal (Lock, No Lock), or if there is a valid and synchronous signal (Sync). The
third column shows the sample frequency detected by the hardware (coarse recognition, 32
kHz, 44.1 kHz, 48 kHz etc.). For MADI, channel format and Frame format are also shown.
User's Guide Fireface UFX+ © RME
17
7.2 Option WDM Devices
The WDM Devices configuration has one button to enter the edit dialog, a status display show-
ing the number of currently enabled WDM devices, and a listbox to change between Stereo or
Multi-Channel devices.
The number represents both record and
playback devices, so ‘1’ means one input
and one output device.
The screenshot to the right shows the stereo
WDM devices available with the UFX+, and
that only Analog 1/2 has been activated.
Any number can be activated. Also only
higher numbered devices might be active.
For example using the MADI output 1/2 for
system based audio does not require to
activate the 15 stereo devices in front. Only
MADI 1/2 will show up in the Windows
Sound control panel.
The checkbox All to the right allows for a
quick check/uncheck of all devices.
Activating all 47 stereo devices at once
may cause temporary freezing or ‘not
responding’ effects. Therefore activate
only the ones which are really needed.
The screenshot to the left shows the multichannel WDM devices available with the
UFX+ after selecting ‘Multi-Channel’ in the
WDM Devices listbox and hitting WDM
Configure. In this example the devices
Analog 1 to 8 and MADI 1 to 8 are active.
Using a multi-channel WDM device allows
for the use of multi-channel playback with
specialized software as well as Surround
sound from DVD or Blu-Ray player software.
Please note that configuring the WDM
device to a specific surround mode in the
control panel Sound requires the device to
have the Speaker property. See next page.
Again the checkbox All to the right allows for
a quick check/uncheck of all devices.

Changing to the tab Speaker presents a list
of all currently activated WDM devices. Any
of these can now get the Speaker property.
Please note that defining more than one
device as Speaker usually makes no sense,
and the speakers also don’t get numbered
or renamed in Windows, so it is impossible
to find out which one is which.
After leaving the dialog with OK the WDM
devices are reloaded so Windows sees their
new properties. You can now assign any
surround mode, from stereo to 7.1, in the
Windows Sound control panel by selecting
the playback device and clicking the
Configure button.

7.3 Tab Global (Thunderbolt only)
This tab includes several options that work on all currently installed and supported interfaces.
Lock Registry
Default: off. Checking this option brings up a dialog to enter a password. Changes in the Settings dialog are no longer written to the registry. As the settings are always loaded from the
registry when starting the computer, this method provides an easy way to define an initial state
of the Fireface UFX+.
Optimize Multi-Client Mixing
Default: off. Checking this option
removes short noise bursts when
multi-client playback starts, but will
also introduce some additional CPU
load. Up to 32 clients are supported.
Enable MMCSS for ASIO activates
support with higher priority for the
ASIO driver. Note: At this time,
activating this option seems to be
useful only with the latest
Cubase/Nuendo at higher load. With
other software this option can
decrease performance. The change
becomes active after an ASIO reset.
Therefore it is easy to quickly check
which setting works better.
ASIO 32 Channel Limit
Default: off. Checking this option
limits the number of ASIO I/Os to 32.
Reducing the number of ASIO channels is required for older versions of
ProTools to prevent them from crashing on start-up.
Change Card Order
This dialog lists all cards currently installed in the system and controlled by the driver. Their
order can then be changed by selecting a card and using the up/down arrows. Confirm the operation with the Apply button. This feature comes in handy if different interfaces are installed
and a specific one of them should always be the first in the ASIO channel list.
At the end of the card info line the current firmware version is shown (Revision).

7.4 Pitch (Thunderbolt only)
Usually soundcards and audio interfaces generate their internal clock (master mode) by a
quartz. Therefore the internal clock can be set to 44.1 kHz or 48 kHz, but not to a value in between. SteadyClock, RME's sensational Low Jitter Clock System, is based on a Direct Digital
Synthesizer (DDS). This superior circuitry can generate nearly any frequency with highest precision.
DDS has been implemented with regard to the needs of professional video applications, as well
as to maximum flexibility. The section Pitch includes both a list of typical video frequencies (so
called pull up/pull down at 0.1% and 4%) and a fader to freely change the basic sample rate in
steps of 1 Hz (!) over a range of +/- 5%.
The Pitch function requires the Fireface to be in clock mode Master! The frequency setting
will only be applied to this one specific Fireface!
Changing the sample rate during record/playback often results in a loss of audio, or brings
up warning messages of the audio software. Therefore the desired sample rate should be
set at least coarsely before starting the software.
Coarse
Coarse modification in steps of 50 Hz is
done by clicking with the mouse to the left
and right of the fader knob.
Fine
Fine modification in steps of 1 Hz is done
by using the left/right cursor keys.
Reset
Ctrl key plus left mouse click.
Application examples
Pitch allows for a simultaneous change of speed and tune during record and playback. From
alignment to other sources up to creative effects – everything is possible.
Pitch enables you to intentionally de-tune the complete DAW. This way, the DAW can match
instruments which have a wrong or unchangeable tuning.
Pitch allows for the change of the sample rate of all WDM devices at the same time. Since Vista
this is no longer possible via the audio program, thus requires a manual reconfiguration of all
WDM devices. Changing the sample rate from the Settings dialog solves this problem. As the
change within the system requires some time, record/playback should not be started immediately after a change.
: The current CPU load can be used to determine if the audio subsystem has finished the
Note
re-configuration.

8. Operation and Usage
8.1 Playback
The Fireface UFX+ can play back audio data in supported formats only (sample rate, bit resolution). Otherwise an error message appears (for example at 22 kHz and 8 bit).
In the audio application being used, Fireface must be selected as output device. This can often
be found in the Options, Preferences or Settings menus under Playback Device, Audio Devices,
Audio etc.
We recommend switching all system sounds off (via >Control Panel /Sounds<). Although the
Fireface UFX+ comes with extensive support for system audio, setting it to be the Default De-
vice for playback could cause problems when working with ASIO.
The screenshot shows a typical configuration dialog of a (stereo) wave editor. Audio data is
sent to an analog or digital port, depending on which has been selected as playback device.
Increasing the number and/or size of audio buffers may prevent the audio signal from breaking
up, but also increases latency i.e. output is delayed. For synchronized playback of audio and
MIDI (or similar), be sure to activate the checkbox ‘Get position from audio driver’.
Note
: Since Vista the audio application can no longer control the sample rate under WDM.
Therefore the driver of the Fireface UFX+ includes a way to set the sample rate globally for all
WDM devices within the Settings dialog, see chapter 7.1.

8.2 DVD-Playback (AC-3/DTS)
AC-3 / DTS
When using popular DVD software players like WinDVD and PowerDVD, their audio data
stream can be sent to any AC-3/DTS capable receiver using the Fireface's SPDIF output. For
this to work, the WDM SPDIF device of the Fireface has to be selected in >Control Panel/
Sound/Playback< as Default device.
The DVD software's audio properties now show the options 'SPDIF Out' or similar. When selecting it, the software will transfer the non-decoded digital multichannel data stream to the Fireface.
: This 'SPDIF' signal sounds like chopped noise at highest level. Try to avoid mixing and
Note
routing the signal to your loudspeakers, as they might get damaged.
Multichannel
PowerDVD and WinDVD can also operate as software decoder, sending a DVD's multichannel
data stream directly to the analog outputs of the Fireface. For this to work select the WDM play-
back device ’Loudspeaker’ of the Fireface in >Control Panel/ Sound/ Playback < as Default.
Additionally the loudspeaker setup, found under Configuration, has to be changed from Stereo
to 5.1 Surround.
PowerDVD's and WinDVD's audio properties now list several multichannel modes. If one of
these is selected, the software sends the decoded analog multichannel data to the Fireface.
TotalMix can then be used to play back via any desired output channels.
The typical channel assignment for surround playback is:
1 - Left
2 - Right
3 - Center
4 - LFE (Low Frequency Effects)
5 - SL (Surround Left)
6 - SR (Surround Right)
Note 1
: Selecting the Fireface to be used as system playback device is against our recommendation, as professional interfaces should not be disturbed by system events. Make sure to reassign the selection after usage or to disable any system sounds (tab Sounds, scheme 'No
audio').
: The DVD player will be synced backwards from the Fireface. This means when using
Note 2
AutoSync and/or word clock, the playback speed and pitch follows the incoming clock signal.

8.3 Channel Count under WDM
The Fireface ADAT optical ports allow to record sample rates of up to 192 kHz using a standard
ADAT recorder. For this to work single-channel data is spread to two or four ADAT channels
using the Sample Multiplexing technique. This reduces the number of available ADAT channels
from 8 to 4 or 2 per ADAT port. The same is true for MADI, the number of channels is reduced
to 32 or 16 respectively.
Whenever the Fireface changes into Double Speed (88.2/96 kHz) or Quad Speed mode
(176.4/192 kHz) all devices no longer available vanish automatically.

8.4 Multi-client Operation
RME audio interfaces support multi-client operation. Several programs can be used at the same
time. The formats ASIO and WDM can even be used on the same playback channels simultaneously. But as WDM uses a real-time sample rate conversion (ASIO does not), all active ASIO
software has to use the same sample rate.
However, a better overview is maintained by using the channels exclusively. This is no limitation
at all, because TotalMix allows for any output routing, and therefore a playback of multiple software on the same hardware outputs.
Inputs can be used from an unlimited number of WDM and ASIO software at the same time, as
the driver simply sends the data to all applications simultaneously.
RME's sophisticated tool DIGICheck is an exception to this rule. It operates like an ASIO host,
using a special technique to access playback channels directly. Therefore DIGICheck is able to
analyse and display playback data from any software, no matter which format it uses.

User's Guide Fireface UFX+ © RME
8.5 Analog Recording
For recordings via the analog inputs the corresponding record device has to be chosen (Fireface UFX+ Analog (x+x)).
The input sensitivity of the rear inputs can be changed in two steps and with adjustable gain in
TotalMix (Input Channel Settings, Level), assuring the highest signal to noise ratio will be
achieved. A further optimization can be achieved by adjusting the source itself. Raise the
source’s output level until the peak level meters in TotalMix reach about –3 dB.
The level of the front-side analog inputs can be optimized via TotalMix (Input Channel Settings,
Gain), or directly at the Fireface UFX+ by the key Mic/Gain and the encoders 1/2. A double
coloured signal and clip LED provides useful information about the current level state.
Further information is found in chapter 19.
It often makes sense to monitor the input signal or send it directly to the output. This can be
done at zero latency using TotalMix FX (see chapter 25).
An automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol
with RME’s ASIO drivers and all ASIO 2.0 compatible programs. When 'ASIO Direct Monitoring'
has been switched on, the input signal is routed in real-time to the output whenever a recording
is started (punch-in).
8.6 Digital Recording
Unlike analog soundcards which produce empty wave files (or noise) when no input signal is
present, digital interfaces always need a valid input signal to start recording.
Taking this into account, RME added a
comprehensive I/O signal status display to
the Fireface UFX+, showing sample
frequency, lock and sync status for every
input, and several status LEDs directly at
the unit.
The sample frequency shown in the fields
Clock Mode and Input Status is useful as a
quick display of the current configuration of
the unit and the connected external
equipment. If no sample frequency is
recognized, it will read ‘No Lock’.
This way, configuring any suitable audio application for digital recording is simple. After selecting the correct input, Fireface UFX+ displays the current sample frequency. This parameter can
then be changed in the application’s audio attributes (or similar) dialog.

8.7 Clock Modes - Synchronization
In the digital world, all devices must be either Master (clock source) or Slave (clock receiver).
Whenever several devices are linked within a system, there must always be a single master
clock.
A digital system can only have one master! If the Fireface’s clock mode is set to 'Master', all
other devices must be set to ‘Slave’.
The Fireface UFX+ utilizes a very user-friendly, intelligent clock control, called AutoSync. In
AutoSync mode, the system constantly scans the digital input for a valid signal. If any valid sig-
nal is found, the Fireface switches from the internal quartz (Clock Mode – Current Internal) to a
clock extracted from the input signal (Clock Mode – Current MADI, ADAT, AES or Word). The
difference to a usual slave mode is that whenever the clock reference fails, the system will
automatically use its internal clock and operate in clock mode Master.
AutoSync guarantees that record and record-while-play will always work correctly. In certain
cases however, AutoSync may cause feedback in the digital carrier, so synchronization breaks
down. To remedy this, switch the Fireface clock mode to ‘Internal’.
RME’s exclusive SyncCheck technology enables an easy to use check and display of the cur-
rent clock status. SyncCheck indicates whether there is a valid signal (Lock, No Lock) for each
input (Word Clock, ADAT, AES, MADI), or if there is a valid and synchronous signal (Sync). See
chapter 39.1.
Via Clock Source a preferred input can be defined. As long as the Fireface sees a valid signal
there, this input will be designated as the sync source, otherwise the other inputs will be
scanned in turn. If none of the inputs are receiving a valid signal, the Fireface automatically
switches clock mode to ‘Internal’.
Under WDM the Fireface will (has to) set
the sample rate. Therefore the error
shown to the right can occur. A stable
signal with a sample rate of 32 kHz is
detected at the ADAT input (Sync), but
Windows audio had been set to 44100 Hz
before. The red colour of the text label
signals the error condition, and prompts
the user to set 32000 Hz manually as
sample rate.
Under ASIO the audio software sets the sample rate, so that such an error will usually not happen – but it can too. In slave mode the external sample rate has priority. Feeding 44.1 kHz will
prevent the ASIO software to set 48 kHz – obviously, as the only way to do so would be to enter
a different clock mode (Master/Internal).
In practice, SyncCheck provides the user with an easy way of checking whether all digital devices connected to the system are properly configured. With SyncCheck, finally anyone can
master this common source of error, previously one of the most complex issues in the digital
studio world.

9. Operation under ASIO
9.1 General
Start the ASIO software and select RME Thunderbolt ASIO or ASIO MADIface USB as the
audio I/O device or the ASIO audio driver.
The Fireface UFX+ supports ASIO Direct Monitoring (ADM).
The Fireface UFX+ MIDI I/Os can be used with both MME MIDI and DirectMusic MIDI.
9.2 Channel Count under ASIO
At a sample rate of 88.2 or 96 kHz, the ADAT optical input and outputs operate in S/MUX mode,
so the number of available channels per port is reduced from 8 to 4. At a sample rate of 176.4
and 192 kHz, the ADAT optical input and output operates in S/MUX4 mode, so the number of
available channels is limited to 2.
The same is true for MADI, the number of channels is reduced to 32 (Double Speed) and 16
(Quad Speed).
: When changing the sample rate range between Single, Double and Quad Speed the
Note
number of channels presented from the ASIO driver will change too. This may require a reset of
the I/O list in the audio software.
Single Speed Double Speed Quad Speed
Fireface Analog 1 to 12 Fireface Analog 1 to 12 Fireface Analog 1 to 12
Fireface AES L / R Fireface AES L / R Fireface AES L / R
Fireface ADAT 1 to 16 Fireface ADAT 1 to 8 Fireface ADAT 1 to 4
Fireface MADI 1 to 64 Fireface MADI 1 to 32 Fireface MADI 1 to 16

9.3 Known Problems
If a computer does not provide sufficient CPU-power, and/or sufficient USB or PCI bus transfer
rates, and/or sufficient PCIe-bus transfer rates, then drop outs, crackling and noise will appear.
Raising the buffer size in the Settings dialog of the Fireface UFX+ helps in most cases. It is also
recommended to deactivate all PlugIns to verify that these are not the reason for such effects.
Further information is found in chapter 39.3.
Another common source of trouble is incorrect synchronization. ASIO does not support asynchronous operation, which means that the input and output signals not only have to use the
same sample frequency, but also have to be in sync. All devices connected to the Fireface
UFX+ must be properly configured for full duplex operation. As long as SyncCheck (in the Set-
tings dialog) only displays Lock instead of Sync, the devices have not been set up properly.
The same applies when using more than one Fireface UFX+ - they all have to be in sync. Else a
periodically repeated noise will be heard.
RME devices support ASIO Direct Monitoring (ADM). Please note that not all programs support
ADM completely or error-free. The most often reported problem is the wrong behaviour of panorama in a stereo channel. Also try to avoid setting the TotalMix FX hardware outputs (third row)
to mono mode. This will most likely break ADM compatibility.
In case of a drift between audio and MIDI, or in case of a fixed deviation (MIDI notes placed
close before or behind the correct position), the settings in Cubase/Nuendo have to be
changed. At the time of print the option 'Use System Timestamp' should be activated. The Fireface UFX+ supports both MME MIDI and DirectMusic MIDI. It depends on the used application
which one will work better.
10. Using more than one Fireface UFX+
The driver supports up to three Fireface UFX+ or a combination of up to three supported interfaces. All units have to be in sync, i.e. have to receive valid sync information (either via word
clock or by using AutoSync and feeding synchronized signals).
• If one of the Firefaces is set to clock mode Master, all others have to be set to clock mode
AutoSync, and have to be synced from the master, for example by feeding word clock. The
clock modes of all units have to be set up correctly in the Fireface Settings dialog.
• If all units are fed with a synchronous clock, i.e. all units show Sync in their Settings dialog,
all channels can be used at once. This is especially easy to handle under ASIO, as the
ASIO driver presents all units as one.
Please be aware that operating more than one Fireface UFX+ may cause resource problems on
the computer side.
Note
: TotalMix is part of the hardware of each Fireface. Up to three mixers are available, but
these are separated and can't interchange data. Therefore a global mixer for all units is not
possible.

Latest Additions.
The second port ADAT channels don’t seem to work
• The optical output ADAT2 has been switched to AES/SPDIF. As can be seen in the block
diagram, all channels and their assignments still exist, but the optical transmitter has been
disconnected from ADAT2 and is now fed from the AES output (channels 13/14). The
ADAT2 playback devices are still usable by routing and mixing them in TotalMix to other outputs.
Playback works, but record doesn’t
• Check that there is a valid signal at the input. If so, the current sample frequency is displayed in the Settings dialog.
• Check whether the Fireface UFX+ has been selected as recording device in the audio application.
• Check whether the sample frequency set in the audio application (‘Recording properties’ or
similar) matches the input signal.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to Master.
Crackle during record or playback
• Increase the number and size of buffers in the ‘Settings’ dialog or in the application.
• Try different cables (coaxial or optical) to rule out any defects here.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to ‘Master’.
• Check the Settings dialog for displayed Errors.
Driver installation and Settings dialog/TotalMix work, but a playback or record is not possible
• While recognition and control of the device are low bandwidth applications, playback/record
needs the full transmission performance. Therefore, defective USB cables with limited
transmission bandwidth can cause such an error scheme.
