1. Introduction Thank you for choosing the RME Babyface. This unique audio system is capable of transferring analog and digital audio data directly to Windows and Mac computers. The latest Plug and Play technology guarantees a simple installation, even for the inexperienced user. Numerous unique features and well thought-out configuration dialog puts the Babyface at the very top of the range of computer-based audio interfaces. The package contains drivers for Windows XP / Vista / 7 and Mac OS X x86 (Intel).
5. First Usage – Quick Start 5.1 Connectors – Controls – Display The top of the Babyface features a rotary encoder with push switch function, 2 keys, 2 LED bands and 5 status LEDs. The two LED bands show the current gain, the input or output level, or indicate the channel to be set, all dependent on the current mode. The lowest LED signals phantom power (+48 V, orange), the highest one overload (Clip, red). The rotary encoder is used to change various parameters directly at the unit.
The short circuit protected, low impedance line outputs do not operate servo balanced! When connecting unbalanced equipment, make sure pin 3 of the XLR output is not connected. A connection to ground will cause a decreased THD (higher distortion) and increased power consumption! The Babyface has two analog microphone inputs that can operate as line inputs with levels up to +12 dBu, when set to 0 dB gain.
5.2 Quick Start After the driver installation (chapter 7 / 15), connect the inputs to the analog signal source. Mount the included breakout cable with or without the extension cable to the D-sub connector of the Babyface. The analog input sensitivity can be changed at the unit (Select In) or in TotalMix (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.

6. Hardware Installation Connect computer and Babyface with the supplied USB cable. Turn on the computer. That‘s it. Chapter 26.3 explains how to find the ideal USB port. 7. Driver and Firmware 7.1 Driver Installation After the Babyface has been recognized, (see 6. Hardware Installation) the hardware assistant finds a Babyface. Insert the RME Driver CD into your CD-ROM drive, and follow further instructions which appear on your computer screen.
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 Babyface/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.
8. Configuring the Babyface 8.1 Settings Dialog - General Configuration of the Babyface is done via its own settings dialog.
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 / 10). Errors does not refer to buffer errors, but USB transmission errors. The display will be reset on any start of a playback/record. More information can be found in chapter 26.3. Options DSP – EQ for Record Switches the 3-band EQ and Low Cut of all input channels into the recording path.
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.
9. Operation and Usage 9.1 Playback In the audio application being used, Babyface must be selected as output device. It can often be found in the Options, Preferences or Settings menus, as Playback Device, Audio Devices, Audio etc. We recommend switching all system sounds off (via >Control Panel /Sound<). Also Babyface should not be the Preferred Device for playback, as this could cause loss of synchronization and unwanted noises.
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 Babyface's SPDIF output. For this to work, the WDM SPDIF device of the Babyface 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.
9.3 Notes on WDM The driver offers one WDM streaming device per stereo pair, like Analog 3+4 (Babyface). 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.
9.4 Channel Count under WDM The Babyface’s ADAT optical interface offers 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 Babyface changes into Double Speed (88.2/96 kHz) or Quad Speed mode (176.4/192 kHz) all devices no longer available vanish automatically.
9.6 Analog Recording For recordings via the analog inputs the corresponding record device has to be chosen (Babyface Analog (x+x)). Channels 1 and 2 of the Babyface have digitally controlled microphone preamps of the highest quality. The digital control offers a gain setting in steps of 3 dB within a range of 9 dB to 60 dB. The configuration is done either directly at the unit via the rotary encoder, or via the Settings panel of the input channels 1 and 2 in TotalMix, with the knob Gain.
9.8 Digital Connections ADAT The ADAT optical input of the Babyface is fully compatible with all ADAT optical outputs. RME's unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch operation, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK cable is sufficient for connection. More information on Double Speed (S/MUX) can be found in chapter 26.4. ADAT In Interface for a device sending an ADAT signal to the Babyface. Carries the channels 1 to 8.
9.9 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 Babyface’s clock mode is set to 'Internal', all other devices must be set to ‘Slave’. The Babyface utilizes a very user-friendly, intelligent clock control, called AutoSync.
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 Babyface supports ASIO Direct Monitoring (ADM). The Babyface 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 output operates in S/MUX mode, so the number of available channels is reduced from 8 to 4. At a sample rate of 176.
10.3 Known Problems If a computer does not provide sufficient CPU-power and/or sufficient USB-bus transfer rates, then drop outs, crackling and noise will appear. Such effects can be avoided by using a higher buffer setting/latency in the Settings dialog of the Babyface. Furthermore PlugIns should be deactivated temporarily to make sure they do not cause these problems. More information can be found in chapter 26.3. Another common source of trouble is incorrect synchronization.
12. DIGICheck Windows The DIGICheck software is a unique utility developed for testing, measuring and analysing digital audio streams. Although this Windows software is fairly self-explanatory, it still includes a comprehensive online help. DIGICheck 5.3 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.
13. Hotline – Troubleshooting The newest information can always be found on our website www.rme-audio.com, section FAQ, Latest Additions. The input signal cannot be monitored in real-time • ASIO Direct Monitoring has not been enabled within the DAW, and/or monitoring has been disabled globally (TotalMix Options). The 8 ADAT channels don’t seem to work • The optical output has been switched to 'SPDIF'.

14. Hardware Installation Connect computer and Babyface with the included USB cable. Mac OS X detects the new hardware as Babyface (serial number). 15. Driver and Firmware 15.1 Driver Installation After the Babyface has been connected, (see 14. Hardware Installation) install the drivers from the RME Driver CD. The driver files are located in the folder Babyface. Installation works automatically by a double-click on the file Fireface USB.pkg.
15.3 Firmware Update The Flash Update Tool updates the firmware of the Babyface to the latest version. It requires an already installed driver. Start the program Babyface USB Flash. The Flash Update Tool displays the current revision of the Babyface 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 unit needs to be reset.
Options DSP – EQ for Record Switches the 3-band EQ and Low Cut of all input channels into the recording path. In case Loopback has been activated the EQ and Low Cut of the Output channel is placed into the recording path. See also chapter 23.5. Optical Out The optical TOSLINK output can operate as ADAT or SPDIF output. The Channel Status is fixed to Consumer state. Note: The optical input detects the incoming format automatically. Clock Mode Sample Rate Used to set the current sample rate.
16.2 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 Babyface’s clock mode is set to 'Internal', all other devices must be set to ‘Slave’. The Babyface utilizes a very user-friendly, intelligent clock control, called AutoSync.
17. Mac OS X FAQ 17.1 Round about Driver Installation The driver with the file suffix zip provided by RME is a compressed archive. Zip is directly supported by OS X, a double click on the file is all one needs to do. The driver consists of a package file (pkg). A double click will start the OS X installer. The actual audio driver appears as a kernel extension file. The installer copies it to >System/ Library/ Extensions<. Its name is FirefaceUSB.kext.
17.5 Channel Count under Core Audio At a sample rate of 88.2 or 96 kHz, the ADAT optical input and output operates in S/MUX mode, so the number of available channels 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. It is not possible to change the number of Core Audio devices without a reboot of the computer. Therefore whenever the Babyface changes into Double Speed (88.
18. Using more than one Babyface OS X supports the usage of more than one audio device within an audio software. This is done via the Core Audio function Aggregate Devices, which allows to combine several devices into one. All units have to be in sync, i.e. have to receive valid sync information via a digital input signal. • If one of the Babyfaces is set to clock mode Master, all others have to be set to clock mode Slave, and have to be synced from the master by feeding ADAT or SPDIF.
20. Hotline – Troubleshooting The newest information can always be found on our website www.rme-audio.com, section FAQ, latest Additions. The unit and drivers have been installed correctly, but playback does not work: • Is Babyface listed in the System Profiler? (Vendor ID 2613). • Has Babyface been selected as current playback device in the audio application? The 8 ADAT channels don’t seem to work • The optical output has been switched to 'SPDIF'.

User's Guide Babyface TotalMix FX User's Guide Babyface © RME 39
21. Routing and Monitoring 21.1 Overview The Babyface includes a powerful digital real-time mixer, the Babyface mixer, based on RME’s unique, sample-rate independent TotalMix technology. It allows for practically unlimited mixing and routing operations, with all inputs and playback channels simultaneously, to any hardware outputs. TotalMix FX adds 3-band parametric equalizer, low cut, echo and reverb. Here are some typical applications for TotalMix: • Setting up delay-free submixes (headphone mixes).
User's Guide Babyface © RME 41
21.2 The User Interface The visual design of the TotalMix mixer is a result of its capability to route hardware inputs and software playback channels to any hardware output. The Babyface has 10 input channels, 12 software playback channels, and 12 hardware output channels: TotalMix can be used in the above view (View Options 2 Rows). The input channel should be placed above the corresponding output channel.
21.3 The Channels A single channel can be switched between mono and stereo mode. The mode is set in the channel settings. Hardware Outputs are always stereo. Channel name. The name field is the preferred place to select a channel by a mouse click. A double click opens a dialog to assign a different name. The original name will be shown when activating the option O-Names in the View Options. Panorama. Routes the input signal freely to the left and right routing destination (lower label, see below).
The lowest field shows the current routing target. A mouse click opens the routing window to select a routing target. The list shows all activated routings of the current channel by arrows in front of the listed entries, the current one is shown in bold letters. An arrow is only shown with an activated routing. A routing is seen as activated when audio data is sent. As long as the fader is set to −∞ the current routing will be shown in bold letters, but not have an arrow in the front. Trim Gain.
A click on the tool symbol opens the channel’s Settings panel with differing elements. For example the Option Inst exists only in input channel 2, and the ADAT channels do not offer the phantom power option. Stereo. Switches the channel to mono or stereo mode. 48V. Activates phantom power at the corresponding input. Serves as power supply for high quality condenser mics. This option should stay off with other sources to prevent failure by spikes. Inst.
A click on EQ opens the Equalizer panel. It is available in all input and output channels, and affects all routings of the respective channel (pre fader). The panel includes a low cut and a 3band parametric equalizer which can be activated separately. Lo Cut. Activated by the button Lo Cut. The slope of the high-pass filter is adjustable between 6, 12, 18 and 24 dB per octave. The cut-off point (-3 dB) is adjustable between 20 Hz and 500 Hz. EQ. Activated by the EQ button. Type.
Notes on the EQ Presets Copy between channels: The EQ Preset menu of all channels is identical. If an EQ setup is stored via Save to on one of the 16 storage places, it is then also available in any other channel via Recall. Copy between Snapshots: The Presets are not saved in Snapshots, therefore do not change when a different Snapshot is loaded. Presets are saved in Workspaces and also loaded with these. Copy between Workspaces: is done by the export and import function of the Preset menu.
21.5 The Control Strip The Control Strip on the right side is a fixed element. It combines different functions that are either required globally, or constantly used, and therefore should not be hidden in a menu. Device selection. Select the unit to be controlled in case more than one is installed on the computer. DSP Meter. Shows the DSP load caused by activated EQs and Low Cuts. The DSP of the Babyface has been designed so that an overload can not occur.
View Options. This area combines different functions of routing, the level meters and the mixer view. Routing ¾ Submix: The Submix view (default) is the preferred view and delivers the quickest overview, operation and understanding of TotalMix. The click on one of the Hardware Output channels selects the respective submix, all other outputs are darkened. At the same time all routing fields are set to this channel.
Snapshots. Snapshots include all mixer settings, but no graphical elements like window positions, window size, number of windows, visible EQs or Settings, scroll states, Presets etc. Only the state wide/narrow of the channels is registered. Moreover the Snapshot is only temporarily stored. Loading a Workspace causes the loss of all stored Snapshots, when these all had not been saved before in a Workspace, or separately via File / Save Snapshot as.
21.6 Reverb and Echo A click on FX in the View Options / Mixer Setup brings up the Output FX panel. Here all parameters for the effects Reverb and Echo are adjusted. The Babyface uses a DSP engine within its FPGA for all the calculations of all the EQs and Low Cuts, in parallel to the DSP engine for TotalMix. However, Reverb and Echo are calculated on the host CPU, means the computer. On current computers, this will not cause any noticeable CPU load.
Special Settings for Envelope and Gated Attack. Length of time for the volume increase of the reverb signal. Also called rise time. Adjustable from 5 ms up to 400 ms. Hold. Length of time for the fixed volume part of the reverb signal. Adjustable from 5 ms up to 400 ms. Release. Length of time for the volume decrease of the reverb signal. Adjustable from 5 ms up to 400 ms. Special Settings for Classic Reverb Time. Sets the duration of the reverb referenced to a volume drop of 20 dB. Adjustable from 0.
Preset. Settings of the Reverb and the Echo can be stored, loaded, and copied between channels at any time. A click on Preset opens a menu with several entries: ¾ Recall: Presets stored before by the user can be selected and loaded ¾ Save to: There are 16 storage places available (Reverb/Echo Preset 1 to 16) ¾ Import: Loads a previously stored TM FX Reverb file (.tmrv) or a TM FX Echo file (.tmeo) ¾ Export: Stores the current state as TM FX Reverb file (.tmrv) or as TM FX Echo file (.
21.8 Settings The dialog Settings can be opened via the Options menu or directly via F3. Talkback ¾ Input. Selects the input channel of the Talkback signal (microphone in control room). Default: None. ¾ Dim. Amount of attenuation of the signals routed to the Phones in dB. Listenback ¾ Input. Selects the input channel of the Listenback signal (microphone in recording room). Default: None. ¾ Dim. Amount of attenuation of the signals routed to the Main Out in dB. Main Out ¾ Recall.
21.9 Hotkeys and Usage TotalMix FX has many hotkeys and mouse/hotkey combinations to speed up and simplify the usage. The Shift key enables a fine-tuning of the gain with all faders and in the Matrix. On all knobs it will speed up the setting. A click on a fader with held down Shift key adds the fader to the temporary fader group. A click in the fader path with held down Shift key will let the fader jump to 0 dB, at the next click to −∞. Same function: Double click of the mouse.
21.10 Menu Options Deactivate Screensaver: When active (checked) any activated Windows screensaver will be disabled temporarily. Always on Top: When active (checked) the TotalMix window will always be on top of the Windows desktop. Note: This function may result in problems with windows containing help text, as the TotalMix window will even be on top of those windows, so the help text isn't readable. Enable MIDI Control: Activates external MIDI control of the TotalMix mixer.
22. The Matrix 22.1 Overview The mixer window of TotalMix looks and operates similar to mixing desks, as it is based on a conventional stereo design. The matrix display presents a different method of assigning and routing channels, based on a single channel or monaural design. The matrix view of the Babyface has the look and works like a conventional patchbay, adding functionality way beyond comparable hardware and software solutions.
The Matrix not always replaces the mixer view, but it significantly enhances the routing capabilities and - more important - is a brilliant way to get a fast overview of all active routings. It shows you in a glance what's going on. And since the Matrix operates monaural, it is very easy to set up specific routings with specific gains. 23. Tips and Tricks 23.1 ASIO Direct Monitoring (Windows) Programs that support ADM (ASIO Direct Monitoring - Samplitude, Sequoia, Cubase, Nuendo etc.
23.5 Recording a Submix - Loopback TotalMix includes an internal loopback function, from the Hardware Outputs to the recording software. Instead of the signal at the hardware input, the signal at the hardware output is sent to the record software. This way, submixes can be recorded without an external loopback cable. Also the playback from a software can be recorded by another software. The function is activated by the Loopback button in the Settings panel of the Hardware Outputs.
Recording a Software's playback In real world application, recording a software's output with another software will show the following problem: The record software tries to open the same playback channel as the playback software (already active), or the playback one has already opened the input channel which should be used by the record software. This problem can easily be solved.
24. MIDI Remote Control 24.1 Overview TotalMix can be remote controlled via MIDI. It is compatible to the widely spread Mackie Control protocol, so TotalMix can be controlled with all hardware controllers supporting this standard. Examples are the Mackie Control, Tascam US-2400 or Behringer BCF 2000. Additionally, the stereo output faders (lowest row) which are set up as Main Out in the Control Room section can also be controlled by the standard Control Change Volume via MIDI channel 1.
24.3 Setup Open the Preferences dialog (menu Options or F3). Select the MIDI Input and MIDI Output port where your controller is connected to. When no feedback is needed select NONE as MIDI Output. Check Enable MIDI Control in the Options menu. 24.4 Operation The channels being under Mackie MIDI control are indicated by a colour change of the name field, black turns to brown. The 8-fader block can be moved horizontally and vertically, in steps of one or eight channels.
24.5 MIDI Control The hardware output set up as Main Out can be controlled by the standard Control Change Volume via MIDI channel 1. With this, the main volume of the Babyface is controllable from nearly any MIDI equipped hardware device. Even if you don't want to control all faders and pans, some buttons are highly desirable to be available in 'hardware'. These are mainly the Talkback and the Dim button, and the monitoring options (listen to Phones submixes).
Examples for sending MIDI strings: - Set input 1 to 0 dB: B0 66 68 - Set input 5 to maximum attenuation: B1 6A 0 - Set playback 1 to maximum: B4 66 7F - Set Output 3 to 0 dB: B8 68 68 Note: Sending MIDI strings requires to use programmer's logic for the MIDI channel, starting with 0 for channel 1 and ending with 15 for channel 16.

26. Technical Background 26.1 Lock and SyncCheck Digital signals consist of a carrier and the data. If a digital signal is applied to an input, the receiver has to synchronize to the carrier clock in order to read the data correctly. To achieve this, the receiver uses a PLL (Phase Locked Loop). As soon as the receiver meets the exact frequency of the incoming signal, it is locked. This Lock state remains even with small changes of the frequency, because the PLL tracks the receiver's frequency.
26.2 Latency and Monitoring The term Zero Latency Monitoring was introduced by RME in 1998 for the DIGI96 series of audio cards. It stands for the ability to pass-through the computer's input signal at the interface directly to the output. Since then, the idea behind has become one of the most important features of modern hard disk recording.
Note: Cubase and Nuendo display the latency values signalled from the driver separately for record and playback. The values do not exactly equal the buffer size (for example 3 ms at 128 samples), instead a higher value is shown, including the time needed for the AD/DA-conversion. Playback shows an even higher value – see Safety Buffer. Safety Buffer An additional small Safety Buffer on the playback side has proven to be very efficient and useful.
Especially with notebooks it can happen that all internal devices and all the sockets/ports are connected to the same controller, with the second controller not used at all. In that case all devices have to use the same bus and interfere with each other. 26.4 DS - Double Speed When activating the Double Speed mode the Babyface operates at double sample rate. The internal clock 44.1 kHz turns to 88.2 kHz, 48 kHz to 96 kHz. The internal resolution is still 24 bit.
26.6 Noise Level in DS / QS Mode The outstanding signal to noise ratio of the Babyface's AD-converters can be verified even without expensive test equipment, by using record level meters of various software. But when activating the DS and QS mode, the displayed noise level will rise from -109 dB to -104 dB at 96 kHz, and –82 dB at 192 kHz. This is not a failure. The software measures the noise of the whole frequency range, at 96 kHz from 0 Hz to 48 kHz (RMS unweighted), at 192 kHz from 0 Hz to 96 kHz.
