5. First Usage – Quick Start
5.1 Connectors – Controls – Display
The front of the Fireface UFX II 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, CC. 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. The LED CC indicates Class Compliant operation.
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.
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.

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 II 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 II can store and load its current state in 6 different
memory slots, called Setups. With this, the Fireface UFX II 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.

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
\MADIface_USB (NOT Fireface_USB)
Start rmeinstaller.exe and follow the instructions of the installer. After installation connect com-
puter and UFX+ using a USB 2 cable. Windows detects the new hardware as Fireface UFX II
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 MADIface'.
6.3 Firmware Update
The Flash Update Tool updates the firmware of the Fireface UFX II to the latest version. It requires an already installed driver.
Start the program fut_mfusb.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 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.
14
User's Guide Fireface UFX II © RME
7. Configuring the Fireface
7.1 Settings dialog – Main Tab
Configuration of the Fireface UFX II 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 II, 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 II 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, and three more
options:
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 II.
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.
The third option, Limit ASIO to 32 channels, is not valid for the UFX II.
User's Guide Fireface UFX II © 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 indicates 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.
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.
TMS activates the transmission of Channel Status data and Track Marker information on AES
and SPDIF inputs. In case these information are not required the feature should be turned off.
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.
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.
16
User's Guide Fireface UFX II © RME
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). 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.
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.).
User's Guide Fireface UFX II © 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
II, 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 ADAT
output 7/8 for system based audio does not
require to activate all ADAT devices in front.
Only ADAT 7/8 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 15 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 II after selecting ‘Multi-Channel’ in the
WDM Devices listbox and hitting WDM
Configure. In this example the devices
Analog 1 to 8 and ADAT 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.
18
User's Guide Fireface UFX II © RME
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.
User's Guide Fireface UFX II © RME
19
8. Operation and Usage
8.1 Playback
The Fireface UFX II 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 II 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 II includes a way to set the sample rate globally for all
WDM devices within the Settings dialog, see chapter 7.1.
20
User's Guide Fireface UFX II © RME
8.2 DVD-Playback (AC-3/DTS)
AC-3 / DTS
When using popular DVD software players, their audio data stream can be sent to any AC3/DTS capable receiver via the Fireface UFX II.
The sample rate must be set to 48 kHz in the UFX II Settings dialog, or the software will

In some cases an UFX II output device has to be selected in >Control Panel / Sound / Playback< and be set as Default, or the software will not recognize it.
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.

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)
: Selecting the Fireface to be used as system playback device is against our recommen-

dation, 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

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.
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.

8.5 Analog Recording
For recordings via the analog inputs the corresponding record device has to be chosen (Fireface UFX II 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 II 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 II, 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 II 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 II 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, 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), or if there is a valid and synchronous signal (Sync). See chap-
ter 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. An AES, SPDIF or ADAT
signal with a sample rate of 48 kHz is used as sync source, but Windows audio had been set to
44100 Hz before. The red color of the text label signals the error condition, and prompts the
user to set 48000 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 ASIO MADIface USB as the audio I/O device or the ASIO
audio driver.
The Fireface UFX II supports ASIO Direct Monitoring (ADM).
The Fireface UFX II 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.
: 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

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 II 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
II 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 II - 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 II 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 II
The driver supports up to three Fireface UFX II 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 II 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.

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 II 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.

13. Hardware, Driver and Firmware Installation
13.1 Hardware and Driver Installation
After the Fireface has been connected to the computer and switched on install the drivers from
the RME Driver CD. The driver files are located in the folder \MADIface_USB. Installation works
automatically by a double-click on the file Fireface USB.pkg.
A special driver for the latest macOS Sierra is also available (currently version 3.01)
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. Installation works automatically by a double-click on this file.
During driver installation the programs Totalmix (TotalMix FX) and Fireface USB Settings are
copied to the Applications folder. They will automatically start into the dock if a Fireface UFX II
is connected. A reboot of the computer is not required.
Driver Updates do not require to remove the existing drivers. Simply install the new driver over
the existing one.
13.2 De-installing the Drivers
In case of problems the driver files can be deleted manually by dragging them to the trash bin:
USB
/Applications/Fireface USB Settings
/Applications/Totalmix
/Library/Extensions/FirefaceUSB.kext
/Users/username/Library/Preferences/de.rme-audio.TotalmixFX.plist
/Users/username/Library/Preferences/de.rme-audio.Fireface_USB_Settings.plist
/Library/LaunchAgents/de.rme-audio.firefaceUSBAgent.plist
Under the latest Mac OS the User/Library folder is not visible in the Finder. To unhide it start
Finder, click on the menu item Go. Hold down the option (alt) key, then click on Library.
13.3 Firmware Update
The Flash Update Tool updates the firmware of the Fireface UFX II to the latest version. It requires an already installed Thunderbolt or USB driver.
Start the program Fireface USB Flash. The Flash Update Tool displays the current revision of
the UFX+ firmware, and whether it needs an update or not. If so, simply press the 'Update' button. A progress bar will indicate when the flash process is finished (Verify Ok).
After the update the Fireface UFX II needs to be reset. This is done by powering down the Fireface for a few seconds. A reboot of the computer is not necessary.
When the update fails (status: failure), the unit's second BIOS will be used from the next cold
boot on (Secure BIOS Technology). Therefore the unit stays fully functional. The flash process
should then be tried again on a different computer.
