5. First Usage – Quick Start
5.1 Connectors – Controls – Display
The front of the MADIface XT has 2 XLR/TRS line and microphone inputs, a stereo
line/headphone output, two rotary encoders with push functionality, four menu keys, a graphical
colour display, and six status LEDs.
The Neutrik combo sockets of
the two Mic/Line inputs provide
XLR and 6.3 mm / 1/4" TRS
connection. They have LEDs for
Signal (SIG), Overload (Clip)
and phantom power (48V).
Channels 3/4 feed the
headphone output, which also
operates as high-quality
unbalanced line output.
The display main screen (Global Level Meters) shows the current state of interface mode (PCIe
orange, USB 2 yellow, USB 3 blue), the sync state of MADI and AES inputs, and incoming and
outgoing MIDI data.
The four keys, the two encoders 1 and 2,
the high-resolution and clear colour display,
and a well thought-out 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 rotary encoder 1 and 2 set the monitoring volume of the rear and front output directly at the
device. Watch the display for further information.
The rear panel of the MADIface XT has two balanced analog outputs, word clock I/O, MADI
coaxial I/O, two MADI optical I/O, USB 3 port (compatible to USB 2), PCI Express connector,
MIDI/AES I/O D-sub for breakout cable, the power socket and a power switch.
Balanced Line Level Outputs. 2 balanced analog outputs via XLR.
Word Clock I/O. BNC. In menu Options – Clock the input can be set to be terminated with 75
Ohms.
MADI I/O coaxial: Standard coaxial MADI ports.
MADI I/O optical: 2 x standard optical MADI ports.
Remote. Mini-DIN. Connector for the optional remote controls with Volume, Store, Dim and
Recall functions.
MIDI I/O and AES/EBU I/O. D-sub connector for the included breakout cable with XLR for AES
I/O and 5-pin DIN for MIDI I/O.
User's Guide MADIface XT © RME

USB 3.0. USB socket for connection to the computer. USB bus power is not supported. Compatible to USB 2.0.
PCI Express. External PCI Express connector for Molex E-PCIe standard cables.
POWER (switch): Turns the MADIface XT on and off.
Socket for power connection. The locking type jack fits the locking type DC connector on the
included power supply. After inserting the connector carefully turn it so that it locks.
The included hi-performance switch mode power supply operates in the range of 100V to 240V
AC. It is short-circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and suppresses mains interference.
5.2 Quick Start
After the driver installation (chapter 6 / 13) connect the TRS or the XLR inputs with the analog
signal source. The input gain can be adjusted in TotalMix FX (Input Channel Settings, 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
MADIface XT. The key MIC/GAIN gives direct access to this setting, which
is then controlled by the encoders 1 and 2. Two LEDs beside the inputs
indicate signal and overload.
All digital inputs show their current state already on the global level meter screen. No signal
(label dark), signal (label flashing red) and sync state (label constantly lit) are easy to see and to
understand. The Settings dialog in Windows and Mac OS X includes a more detailed analysis of
the input signal state.
The digital outputs of the MADIface XT provide AES/EBU (SPDIF compatible) and MADI signals
at the corresponding ports. They can be set up in different ways in the menu SETUP/REV, Options, MADI Settings, or the driver’s Settings dialog.
The output level of the current Main output (as selected in TM FX) and
Phones (locked to the front output) can be adjusted right from the front.
While in the global level meter screen simply turn encoder 1 or 2. More
options, like balance, phase, mute or stereo/mono are available in the
CHANNEL menu.
The MADIface XT can store and load its current state in 6 different
memory slots, called Setups. With this, the MADIface XT 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 Settings dialog or TotalMix. These include the choice of sample rate and the mix settings.

6. Hardware, Driver and Firmware Installation
6.1 Driver Installation
To simplify installation it is recommended to first install the drivers before the card 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
\HDSPe FX for external PCI Express
\MADIface_USB for USB 3 and USB 2.0
Start rmeinstaller.exe and follow the instructions of the installer. After installation connect com-
puter and XT using a USB 2, USB 3.0 or external PCI Express cable. Windows detects the new
hardware as MADIface XT 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 HDSPe FX
(WDM)' or 'RME MADIface USB'.
.
6.3 Firmware Update
The Flash Update Tool updates the MADIface XT to the latest firmware version. It requires an
already installed driver.
Start the program hdspe_fx_fut.exe (PCI) or fut_mfusb.exe (USB). The Flash Update Tool
displays the current revision of the MADIface XT and whether it needs an update or not. If so,
then please press the 'Update' button. A progress bar will indicate when the flash process is
finished. The bar moves slowly first (program), then faster (verify).
After the update the MADIface XT needs to be reset. This is done by powering down the XT for
a few seconds. A reboot of the computer is not necessary.
To reduce the time needed for the flash process the tool updates only the parts of the firmware
that are present in a newer version. The option Flash All forces the tool to update all parts.
When the update fails (status: failure), the card's second BIOS will be used from the next cold
boot on (Secure BIOS Technology). Therefore the card stays fully functional. The flash process
should then be tried again on a different computer.

User's Guide MADIface XT © RME
7. Configuring the MADIface XT
7.1 Settings Dialog – Main Tab
Configuration of the MADIface XT is done via its own settings dialog. The panel 'Settings' can
be opened:
• by clicking on the hammer/flame symbol in the Task Bar's notification area
The mixer of the MADIface XT, TotalMix FX, can be opened:
• by clicking on the DSP symbol in the Task Bar's notification area
The HDSPe hardware 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
• WDM Device Configuration
• Current sample rate
• Synchronization behaviour
• Configuration of digital I/Os
• Input selection
• 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 status displays at the bottom of the
dialog box give the user precise
information about the current status of
the system, and the status of all digital
signals.
The tab About provides information
about the current driver version of the
MADIface XT. The USB driver also has
the options Lock Registry and Enable
MMCSS for ASIO on this page (see tab
Global).
User's Guide MADIface XT © RME
13
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). While ASIO can use any offered
buffer size, WDM is limited to 256 (XP) or 512 samples (Win 7/8). The driver handles this automatically, higher settings are only applied to ASIO while WDM will stay at 256/512 internally.
Errors (USB only) 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 30.4.
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
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, MADI, AES). If the selected source isn't available (No Lock), the unit will change to the
next available one (RME’s AutoSync behaviour). 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 7.4.
Output Format
AES
The channel status of the AES output signal can be set to Consumer or Professional. For fur-
ther details please refer to chapter 21.2.
MADI 1/2/3
Defines the format of the MADI output signal. MADI can be a 56 or 64 channel signal.
96 kHz
Word
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.
MADI 1/2/3
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.
14
User's Guide MADIface XT © RME
Options
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 27.5.
Word Clock In Term.
Checking this option terminates the
word input internally with 75 Ohms.
TMS
TMS activates the transmission of
Channel Status data and Track
Marker information from the AES
and MADI input signal.
Redundancy Mode
With redundancy mode active the
number of input channels is reduced
to 66 (AES plus 1 MADI). The two
other MADI ports serve as fail safe
inputs, used as soon as the signal
on the 'Current MADI Input' fails.
This setting is also a perfect choice if
the card is used as single MADI I/O,
saving resources and providing
simpler channel selection dialogs.
Mirror MADI1 Output to MADI2/3
This option provides a quick and
simple solution to mirror the first
MADI output to outputs 2 and 3. The
outputs are reduced to 2+4+64
channels (AES, 2 x analog, one
MADI port). All the data routed and
mixed to MADI port 1 is sent to
MADI port 2/3 as well.
Isochronous Streaming (USB 3 only)
The XT uses a special transmission mode with error correction to record data. In case the XT’s
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 30.4.
WDM Devices (USB 2/3)
Reduce the number of WDM devices to the ones really needed to improve performance. See
chapter 7.2.
Input Status
Displays the state of the current input signal:
• Clock state (No Lock, Lock, Sync)
• Sample rate (coarse)
• MADI Frame format (48K or 96K)
• Channel format (64 or 56 channels)
Sync Check
RME’s exclusive SyncCheck technology provides an easy to use check and display of the cur-
rent clock status. The clock state column indicates whether no signal (No Lock), a valid signal
(Lock) or a valid and synchronous signal (Sync) is present at each of the digital inputs.

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 select 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 XT,
and that only MADI 1/2 has been activated.
Any number can be activated. Also only
higher numbered devices might be active.
For example using the MADI 2 output for
system based audio does not require to
activate all 32 stereo devices of MADI 1.
Only MADI 65+66 will show up in the
Windows Sound control panel.
The checkbox All to the right allows for a
quick check/uncheck of all devices.
Warning! Activating all 99 stereo devices
will most probably freeze your computer!
Activate only the ones which are really
needed!
The screenshot to the left shows the multichannel WDM devices available with the
MADIface XT after selecting ‘Multi-Channel’
in the WDM Devices listbox and hitting
WDM Configure. In this example the
devices MADI 1 to 8 and MADI 65 to 72 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.
16
User's Guide MADIface XT © 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 MADIface XT © RME
17
7.3 Tab Global (PCI Express Mode)
This tab includes several options that work on all currently installed cards.
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 MADIface XT.
Optimize Multi-Client Mixing
Default: off. Checking this option
removes short noise bursts when multiclient playback starts, but will also
introduce some additional CPU load.
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 cards 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).

User's Guide MADIface XT © RME
7.4 Settings Dialog – Pitch (E-PCIe 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 into the MADIface XT 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 MADIface XT to be in clock mode Master! The frequency
setting will only be applied to this one specific card!
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.
: For technical reasons, Pitch is not available with USB 3 and USB 2.

7.5 Clock Modes - Synchronisation
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 card’s clock mode is set to 'Master', all
other devices must be set to ‘Slave’.
The MADIface XT 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 card switches from the internal quartz (Clock Mode – Current Internal) to a
clock extracted from the input signal (Clock Mode – Current MADI, Word or AES). 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 normal 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 XT’s clock mode to ‘Internal’.
RME’s exclusive SyncCheck technology enables an easy to use check and display of the current clock status. Input Status indicates whether there is a valid signal (Lock, No Lock) for each
input (Word, MADI, AES), or if there is a valid and synchronous signal (Sync). See chapter
30.2.
Via Clock Source a preferred input can be defined. As long as the card 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 MADIface automatically
switches clock mode to ‘Master’.
Under WDM the unit 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 Word Clock 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.

8. Operation and Usage
8.1 Playback
The MADIface XT 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, the XT 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 off all system sounds (via >Control Panel /Sounds<). Also
MADIface should not be the Preferred Device for playback, as this could cause loss of synchro-
nization and unwanted noises. If you feel you cannot do without system sounds, you should use
on-board sound or any cheap sound card and select this one as Preferred Device in >Control
Panel /Multimedia /Audio< or >Control Panel /Sound /Playback<.
The screenshot to the
right shows a typical
configuration dialog as
displayed by a (stereo)
wave editor. After
selecting a playback
device, audio data is
sent to the according
channels.
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’.
The MADIface XT allows sample rates of up to 192 kHz via MADI. In this mode, only 16 channels are functional per MADI port.
Note
: Since Vista the audio application can no longer control the sample rate under WDM.
Therefore the driver of the MADIface XT includes a workaround: the sample rate can be set
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 via the MADIface XT. For this to work an
output wave device 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 these, the software will transfer the non-decoded digital multichannel data stream to the
MADIface. Naturally a successful decoding also requires a MADI to AES converter like the RME
ADI-642, converting the playback signals to stereo AES3 or SPDIF.
: This 'SPDIF' signal sounds like chopped noise at highest level. The channels Loud-
Note
speaker do not support digital AC-3/DTS playback.
Multichannel
PowerDVD and WinDVD can also operate as software decoder, sending a DVD's multichannel
data stream directly to the outputs of the MADIface XT. For this to work select the WDM playback device ’Loudspeaker’ of the MADIface XT in
XP: >Control Panel/ Sounds and Multimedia/ Audio<, and 'Use only default devices' has to be
checked. Additionally the loudspeaker setup, found under >Volume/ Speaker Settings/ Ad-
vanced< has to be changed from Stereo to 5.1 Surround.
Vista/7/8: >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 MADIface
XT. 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
professional devices are not specialized to play back system sounds, and shouldn't be disturbed by system events. To prevent this be sure to re-assign this setting after usage or disable
any system sounds (tab Sounds, scheme 'No audio').
Note 2
Sync and/or word clock, the playback speed and pitch follows the incoming clock signal.
: Setting the unit to be used as system playback device is against common sense, as
: The DVD player will be synced backwards from the MADIface. So when using Auto-

8.3 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. 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 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.
8.4 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 MADIface XT, showing sample frequency, lock and sync status for every input.
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. MADIface XT
displays the current sample frequency of the currently used input. This parameter can then be
changed in the application’s audio properties (or similar) dialog.
8.5 Analog Recording
For recordings via the analog inputs the corresponding record device has to be chosen (MADIface XT Analog (1+2)).
The level of the front-side analog inputs can be optimized via TotalMix (Input Channel Settings,
Gain), or directly at the MADIface XT by the key MIC/GAIN and the encoders 1/2. Here a signal
and clip LED provide useful information about the current level state.
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.
Further information is found in chapter 20.
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 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).

9. Operation under ASIO
9.1 General
Start the ASIO software and
select ASIO HDSPe FX or
ASIO MADIface USB as the
audio I/O device.
MADIface XT supports ASIO
Direct Monitoring (ADM).
Its MIDI I/Os can be used
with both MME MIDI and
DirectMusic MIDI.
At a sample rate of 88.2 or 96
kHz (Double Speed mode),
the number of channels available at the MADI input and
output is halved. At a sample
rate of 176.4 or 192 kHz
(Quad Speed mode), the
number of channels is reduced to 16.
: 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.
9.2 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 MADIface XT 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 30.4.
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 MADIface XT
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 MADIface XT - they all have to be in sync. Else a
periodically repeated noise will be heard.
MADIface XT 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. 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
MADIface supports both MME MIDI and DirectMusic MIDI. It depends on the used application
which one will work better.

User's Guide MADIface XT © RME
10. Using multiple MADIface XT
The current driver supports operation of up to three MADIface XT. 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 XTs is set to clock mode Master, all others have to be set to clock mode Slave,
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 their Settings dialogs.
• 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 cards as one.
TotalMix is part of the hardware of each unit. Up to three mixers are available, but these
Note:
are separated and can't interchange data. Therefore a global mixer for all units is not possible.
11. DIGICheck Windows
The DIGICheck software is a unique utility developed for testing, measuring and analysing digital audio streams. Although this software is fairly self-explanatory, it still includes a comprehensive online help. DIGICheck 5.81 operates as multi-client ASIO host, therefore can be used in
parallel to any software with both inputs and outputs (!). The following is a short summary of the
currently available functions:
• Level Meter. High precision 24-bit resolution, 2/8/198 channels. Application examples: Peak
level measurement, RMS level measurement, over-detection, phase correlation measurement, dynamic range and signal-to-noise ratios, RMS to peak difference (loudness), long
term peak measurement, input check. Oversampling mode for levels higher than 0 dBFS.
Vertical and horizontal mode. Slow RMS and RLB weighting filter. Supports visualization according to the K-system.
• Hardware Level Meter for Input, Playback and Output. As above, receive pre-calculated
directly from the MADIface hardware with near zero CPU load.
• Spectral Analyser. World wide unique 10-, 20- or 30-band display in analog bandpass-filter
technology. 192 kHz-capable!
• Vector Audio Scope. World wide unique Goniometer showing the typical afterglow of an
oscilloscope-tube. Includes Correlation meter and level meter.
• Totalyser. Spectral Analyser, Level Meter and Vector Audio Scope in a single window.
• Surround Audio Scope. Professional Surround Level Meter with extended correlation
analysis, ITU weighting and ITU summing meter.
• ITU1770/EBU R128 Meter. For standardized loudness measurements.
• Bit Statistics & Noise. Shows the true resolution of audio signals as well as errors and DC
offset. Includes Signal to Noise measurement in dB and dBA, plus DC measurement.
• Channel Status Display. Detailed analysis and display of SPDIF and AES/EBU Channel
Status data.
• Global Record. Long-term recording of all channels at lowest system load.
• Completely multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs or outputs!
To install DIGICheck, go to the \DIGICheck directory on the RME Driver CD and run setup.exe.

Latest Additions.
The dialog 'New hardware component found’ does not appear:
• Check whether the PCI Express interface is correctly inserted in the PCI Express slot.
The card and drivers have been installed correctly, but playback does not work:
• Check whether the MADIface XT appears in the Device Manager. When the device has a
yellow exclamation mark, then there is a conflict.
The input signal cannot be monitored in real-time
• ASIO Direct Monitoring has not been enabled, and/or monitoring has been disabled globally
(wrong mix setup in TotalMix)
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 MADIface XT 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.
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 ‘Internal’.
Windows boot time became much worse since the MADIface XT has been added
• Deactivate all WDM devices that are unused in the card’s settings dialog. If only ASIO is
used disable all.

13. Driver and Flash Update
13.1 Driver Installation
After the MADIface 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
\Fireface_USB for USB 3 and USB 2.0
\HDSPe FX for external PCI Express
Installation works automatically by a double-click on the file Fireface_USB.pkg or
hdspe_fx.pkg.
During driver installation the programs Totalmix (TotalMix FX) and Fireface USB Settings or
HDSPe FX Settings are copied to the Applications folder. They will automatically start into the
dock if a MADIface 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.
: PCI Express and USB can be connected at the same time. However, the unit will use only
Note
one port. If no interface mode is pre-defined, then the port that becomes active first at the computer will be used.
13.2 De-installing the Drivers
In case of problems the driver files can be deleted manually by dragging them to the trash bin:
PCI Express

13.3 Firmware Update
The Flash Update Tool updates the MADIface XT card to the latest firmware version. It requires
an already installed driver.
Start the program HDSPe FX Flash Update or RME USB Series Flash Tool. The Flash Up-
date Tool displays the current revisions inside the XT, 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. The bar moves slowly first (program), then faster (verify).
After the update the MADIface XT needs to be reset. This is done by powering down the XT for
a few seconds. A reboot of the computer is not necessary.
To reduce the time needed for the flash process the tool updates only the parts of the firmware
that are present in a newer version. The option Flash All forces the tool to update all parts.
When the update fails (status: failure), the card's second BIOS will be used from the next cold
boot on (Secure BIOS Technology). Therefore the card stays fully functional. The flash process
should then be tried again on a different computer.

14. Configuring the MADIface XT
14.1 Settings Dialog
Configuring the MADIface XT is done via its own settings dialog. The panel 'Settings' can be
opened by clicking on the hammer or flame icon in the dock. The mixer of the MADIface XT,
TotalMix FX, can be opened by clicking on the DSP FX icon in the dock.
The MADIface hardware 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:
• Configuration of digital I/Os
• Hardware Options
• Synchronization behaviour
• Current sample rate
• State of inputs and outputs
Any changes performed in the Settings dialog are applied immediately
- confirmation (e.g. by 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.
The status display at the bottom of
the dialog box gives the user
precise information about the
current status of the system, and
the status of all digital signals.
Use the drop down menu
Properties For to select the card to
be configured. To the right the
current firmware and driver version
is shown.
Output Format
AES
The channel status of the AES output signal can be set to Consumer or Professional. For fur-
ther details please refer to chapter 21.2.
MADI 1/2/3
Defines the format of the MADI output signal. MADI can be a 56 or 64 channel signal.
96 kHz
Word
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.
MADI 1/2/3
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.
