5. First Usage – Quick Start
5.1 Connectors – Controls – Display
The front of the Fireface UFX features four instrument and microphone inputs, two stereo headphone outputs, three rotary encoders with push functionality, a graphical colour display, 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 and can
be used as instrument input as well.
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 / Playback from
the device (DSP firmware 138 or up).
State LEDs. WC, AES, ADAT1, ADAT2. 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 9.8 / 16.2,
Clock Modes - Synchronization.
MIDI LEDs. Indicate separately for input and output if MIDI are received or transmitted.
The blue LED USB and FW extinguish if no USB or FireWire connection has been initialised, or
has been interrupted (error, cable not connected etc.).
The rotary encoder Volume sets the monitoring volume directly at the device. Pushing the but-
ton will change between Main Out, Phones 1 and Phones 2. Watch the display for further information.
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.

UFX accepts the commonly used
digital audio formats, SPDIF as well
as AES/EBU.
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.
Word Clock I/O. BNC. A push switch activates internal termination (75 Ohms). With termination
activated the yellow LED besides the switch will light up.
Remote. Mini-DIN. Connector for the optional remote control with Volume, Store, Dim and Re-
call functions.

5.2 Quick Start
After the driver installation (chapter 7 / 15) 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, Level), 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 analog line inputs of the Fireface UFX can be used with +4 dBu and -10 dBV signals. The
electronic input stage can handle balanced (XLR, TRS jacks) and unbalanced (TS jacks) input
signals correctly.
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 available in TotalMix (Output Channel Settings, Level) or the Channel Settings
directly at the device.
The output signal of channels 9/10 and 11/12 is available on the front.
Their output level can be set using the VOLUME encoder. This output is a
very low impedance type, which can also be used to connect headphones.
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 25).
In online mode some settings are greyed out, as these should be changed only at the computer
in the Settings dialog or in TotalMix. These include the choice of sample rate and the Mix settings.

6. Hardware Installation
USB
• Use the power cord to connect the Fireface with any suitable power outlet.
• Connect computer and Fireface using the supplied USB cable.
• Power on computer and UFX.
Chapter 33.3 explains how to find the ideal USB port.
FireWire
• Use the power cord to connect the Fireface with any suitable power outlet.
• Connect computer and Fireface using the supplied 6-pin FireWire cable (IEEE1394a). In
case your computer does not have any FireWire port, PCI, PCI Express, CardBus and ExpressCard cards can be used to add them. In case your notebook does not have a 6-pin
jack, or did not include a 6-pin to 4-pin adapter: such adapters are available in your local
computer store.
• Power on the computer. Switch on the Fireface when Windows shows the desktop.
: FireWire and USB can be connected at the same time, but it is not recommended. Upon
Note
start of the computer the port that becomes active first will be used. With no port active the unit
searches on both USB and FireWire until it finds an active one.
7. Driver and Firmware
7.1 Driver Installation
After the Fireface UFX has been switched on (see 6. Hardware Installation), the hardware as-
sistant finds a Fireface UFX. Insert the RME Driver CD into your CD-ROM drive, and follow
further instructions which appear on your computer screen. The driver files are located in the
directory \Fireface_USB and \Fireface_FW on the RME Driver CD.
Windows now installs the driver of the Fireface UFX and
registers it as a new audio device in the system. After a
reboot, the symbols of TotalMix and Settings dialog will
appear in the task bar.
In case the Hardware Wizard does not show up automatically after installation of the card,
do not attempt to install the drivers manually! An installation of drivers for non-recognized
hardware will cause a blue screen when booting Windows!
In Windows 7 Microsoft removed the automatic start of the Driver Software Update dialog. The-
refore this dialog has to be started manually after the failed driver installation. Hit the Windows
key, type 'Device Manager', start the Device Manager by selecting it from the list and hit Enter.
The device is shown with a yellow warning symbol. Usually it is already found in the correct
category, Sound, Video and Game Controller (Plug & Play detects a multimedia device). Right
click on the device and select 'Update Driver Software' from the context menu.
The dialog Update Driver Software appears. Now follow the instructions given below.
Possible reasons why a Fireface is not found automatically:
• The USB or FireWire port is not active in the system (check in Device Manager)
• The USB or FireWire cable is not, or not correctly inserted into the socket
14
User's Guide Fireface UFX © RME
7.2 Driver Update
When facing problems with the automatic driver update, the user-driven way of driver installation will work.
Under >Control Panel /System /Device Manager /Sound, Video and Game Controllers /RME
Fireface UFX /Properties /Driver< you'll find the 'Update Driver' button.
XP: Select 'Install from a list or specific location (advanced)', click 'Next', select 'Don't
search I will choose the driver to install', click 'Next', then 'Have Disk'. Now point to the
driver update's directory.
Vista/7: Select 'Browse my computer for driver software', then 'Let me pick from a list of
device drivers from my computer', then 'Have Disk'. Now point to the driver update's direc-
tory.
This method also allows for the installation of older drivers than the currently installed ones.
7.3 De-installing the Drivers
A de-installation of the Fireface's 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. These entries can be removed from the registry by a software de-installation request. This request can be found (like all
de-installation entries) in Control Panel, Software. Click on the entry 'RME Fireface'.
7.4 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_usb.exe. 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 Fireface
for a few seconds.
Attention
off for less than 5 seconds, because Windows
completely unloads the driver, which takes
some time to finish.
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.
: the Fireface should not be switched

8. Configuring the Fireface
8.1 Settings dialog - General
Configuration of the Fireface UFX is done via its own settings dialog. The panel 'Settings' can
be opened:
• by clicking on the fire symbol in the Task Bar's system tray
The mixer of the Fireface UFX, TotalMix, can be opened:
• by clicking on the double arrow 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 following is available in the 'Settings' dialog:
• 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
UFX.
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 10.1).
Errors does not refer to buffer errors, but USB and FireWire transmission errors. The display
will be reset on any start of a playback/record. More information can be found in chapter 33.3 /
33.4.
16
User's Guide Fireface UFX © RME
Options
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 29.5.
ADAT2
This optical TOSLINK output can operate as ADAT or AES/SPDIF output.
AES Input
Defines the input for the AES (SPDIF) signal. 'AES' relates to the XLR socket, 'ADAT2' to the
second optical TOSLINK input. TMS activates the transmission of Channel Status data and
Track Marker information. In case these information are not required the feature should be turned off.
AES Output
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 output. For further details please refer to
chapter 23.2.
Word Clk Out
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.
Clock Mode
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 and ADAT2). 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 as Current.
Pitch
More information on Pitch is available in chapter 8.2.
Input Status
Indicates for each input (Word, AES, ADAT1, ADAT2) 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.). In
Clock Mode the clock reference is shown. See also chapter 33.1.
Bandwidth (only for the FireWire driver)
Allows to reduce the amount of bandwidth used on the FireWire bus. See chapter 33.4.
All channels (default) activates all 30 input and output channels.
Analog + AES + ADAT1 disables channels 23–30 (ADAT2).
Analog + AES activates all 12 analog channels plus AES.
Analog 1-8 activates only the first eight analog channels.
User's Guide Fireface UFX © RME
17
8.2 Settings Dialog - Pitch
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 into the Fireface 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, but only after at least 5 seconds after a change.
Tip: the current CPU load can be used to determine if the audio subsystem has finished the re-
configuration.

9. Operation and Usage
9.1 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 strongly recommend switching all system sounds off (via >Control Panel /Sounds<). Also
Fireface should not be the Preferred Device for playback, as this could cause loss of synchroni-
zation and unwanted noises. If you feel you cannot do without system sounds, you should con-
sider buying a cheap Blaster clone and select this as Preferred Device in >Control Panel
/Multimedia /Audio< or >Control Panel /Sound /Playback<.
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 on Windows Vista/7
Since Vista the audio application can no longer control the sample rate under WDM. Instead the
user has to work himself through numerous settings (16 with the UFX!), and to set the sample
rate to the same value per stereo device.
Therefore the driver of the Fireface UFX includes a workaround: the sample rate can be set
globally for all WDM devices within the Settings dialog, see chapter 8.1.

9.2 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/
Sounds and Multimedia/ Audio< or >Control Panel/ Sound/Playback<. Also check 'use preferred
device only'.
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 playback device ’Loudspeaker’ of the Fireface in
XP: >Control Panel/ Sounds and Multimedia/ Audio<, and check 'Use only default devices'.
Additionally the loudspeaker setup, found under >Volume/ Speaker Settings/ Advanced< has to
be changed from Stereo to 5.1 Surround.
Vista/7: >Control Panel/ Sound/ Playback < as ‘Standard’. 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)
: Selecting the Fireface to be used as system playback device is against our recommen-
Note 1
dations, 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').
Note 2
: The DVD player will be synced backwards from the Fireface. This means when using
AutoSync and/or word clock, the playback speed and pitch follows the incoming clock signal.

9.3 Notes on WDM
The driver offers a WDM streaming device per stereo pair, like Analog 3+4 (Fireface UFX).
WDM streaming is Microsoft's current driver and audio system, directly embedded into the operating system. WDM streaming is hardly usable for professional music purposes, as all data is
processed by the so called Kernel Mixer, causing a latency of at least 30 ms. Additionally, WDM
can perform sample rate conversions unnoticed, cause offsets between record and playback
data, block channels unintentionally and much more.
Several programs do not offer any direct device selection. Instead they use the playback device
selected in Windows under
XP: <Control Panel/ Sounds and Multimedia/ Audio>
Vista/7: <Control Panel/ Sound/ Playback>
The program Sonar from Cakewalk is unique in many ways. Sonar uses the so called WDM
Kernel Streaming, bypassing the WDM mixer, thus achieves a similar performance to ASIO.
Because of the driver's multichannel streaming ability Sonar not only finds the stereo device
mentioned above, but also the 8-channel interleaved devices, and adds the channel number at
the end:
Fireface Analog (1+2) 1/2 is the first stereo device
Fireface Analog (3+4) is the next stereo device
Fireface Analog (1+2) 3/4 are the channels 3/4 of the first 8-channel interleaved device.
It is not recommended to use these special interleaved devices. Also it is not possible to use
one stereo channel twice (the basic and the interleaved device).
Multi-Channel using WDM
The WDM Streaming device Loudspeaker (Analog 1+2) of the RME driver can operate as usual
stereo device, or as up to 8-channel device.
An 8-channel playback using the Windows Media Player requires the speaker setup 7.1 Sur-
round. Configure as follows:
XP: >Control Panel /Sounds and Multimedia /Audio /Volume /Speaker Settings /Advanced <
Vista/7: >Control Panel /Sound /Playback /Loudspeaker /Configure <

9.4 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.
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.

Note: Under Vista/7 the analog outputs 1/2 show up as Loudspeaker.
9.5 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.

9.6 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 three steps 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 21.
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 (see chapter 27).
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).
9.7 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.

9.8 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 ADAT, AES or Word). The differ-
ence 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, e.g. when the inputs and outputs of a DAT machine are connected directly to
the Fireface UFX, AutoSync may cause feedback in the digital carrier, so synchronization
breaks down. To solve this problem switch the Fireface clock mode to Master (Clock Source –
Internal).
The Fireface's ADAT optical and AES inputs operate simultaneously. Because there is no input
selector however, the unit has to be told which one of the signals is the sync reference (a digital
device can only be clocked from a single source). By selecting a Clock Source a preferred input
is defined. As long as the unit sees a valid signal there, this input will be designated as the sync
source.
In some situations changing the clock mode can not be avoided. Example: An ADAT recorder is
connected to the ADAT input (ADAT immediately becomes the AutoSync source) and a CD
player is connected to the AES input. Try recording a few samples from the CD and you will be
disappointed - few CD players can be synchronized. The samples will inevitably be corrupted,
because the signal from the CD player is read with the clock from the ADAT. In this case the
Clock Source should be temporarily set to AES.
RME’s exclusive SyncCheck technology (first implemented in the Hammerfall) offers an easy to
use check and display of the current clock status. SyncCheck indicates whether there is a valid
signal (Lock, No Lock) for each input (Word Clock, ADAT, AES), or if there is a valid and synchronous signal (Sync). In the field Clock Mode the clock reference is shown. See chapter 33.1.
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 can not happen. If the input
sample rate is different then there will
be no Sync indication.
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.

10. Operation under ASIO
10.1 General
Start the ASIO software and select ASIO Fireface USB as the audio I/O device or the audio
driver.
The Fireface UFX supports ASIO Direct Monitoring (ADM).
The Fireface UFX MIDI I/O can be used with both MME MIDI and DirectMusic MIDI.
10.2 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.
: 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

10.3 Known Problems
If a computer does not provide sufficient CPU-power and/or sufficient USB or PCI* 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
33.3.
*The note on PCI is not an error in this manual: very often FireWire controllers are connected to
the PCI bus. Therefore the same problems known from PCI audio cards can occur with FireWire audio interfaces as well. Further information is found in chapter 33.4.
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 Settings
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.
Fireface UFX supports ASIO Direct Monitoring (ADM). Please note that not all programs sup-
port ADM completely or error-free. The most often reported problem is the wrong behaviour of
panorama in a stereo channel.
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 supports both MME MIDI and DirectMusic MIDI. It depends on the used application which
one will work better.
11. Using more than one Fireface UFX
The current driver supports up to three Fireface UFX. 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.
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.
In real-world an operation of more than one Fireface UFX makes no sense and is therefore not
actively supported by RME. Each further unit would lead to problems on the USB and FireWire
bus, caused by the high number of channels. The UFX has been developed as monitor controller and – not extendable – digital mixer. It makes more sense to connect external converters to
the ADAT I/Os of the UFX, adding up to 16 channels of analog record and analog playback.

Latest Additions.
The 8 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 FireWire transmission performance. Therefore, defective FireWire cables with
limited transmission bandwidth can cause such an error scheme. The same is true for USB
cables.

14. Hardware Installation
USB
• Use the power cord to connect the Fireface with any suitable power outlet.
• Connect computer and Fireface using the supplied USB cable.
• Power on computer and UFX.
The Mac OS detects the hardware as Fireface (serial number).
FireWire
• Use the power cord to connect the Fireface with any suitable power outlet.
• Connect computer and Fireface using the supplied 6-pin FireWire cable (IEEE1394a). In
case your computer does not have any FireWire port, PCI, PCI Express, CardBus and ExpressCard cards can be used to add them. In case your notebook does not have a 6-pin
jack, or did not include a 6-pin to 4-pin adapter: such adapters are available in your local
computer store.
• Power on computer and UFX.
: FireWire and USB can be connected at the same time. However, the unit will use only
Note
one port. After power-on, USB has priority.
15. Driver and Firmware
15.1 Driver Installation
After the Fireface has been switched on (see 14. Hardware Installation) install the drivers from
the RME Driver CD. The driver files are located in the folder \Fireface_USB and \Fireface_FW
on the RME Driver CD. Installation works automatically by a double-click on the file Fireface
USB.pkg or Fireface.pkg.
RME recommends downloading the latest driver version from the RME website. If done, the
procedure is as follows:
A double-click onto driver_usb_mac.zip expands the archive file to Fireface USB.pkg. Instal-
lation works automatically by a double-click on this file.
A double-click onto fireface_x86.zip expands the archive file to Fireface.pkg. Installation
works automatically by a double-click on this file.
During driver installation the programs Fireface USB Settings and Fireface USB Mixer (TotalMix FX), or Fireface Settings and Fireface Mixer respectively, are copied to the Applica-
tions folder. It is recommended to link these two programs to the Dock so that they are always
available.
Possible reasons why a Fireface is not found automatically:
• The USB or FireWire port is not active in the system (check in System Profiler)
• The USB or FireWire cable is not, or not correctly inserted into the socket
