9.6 Analog Recording  
For recordings via the analog inputs the corresponding record device has to be chosen (Baby-
face Pro Analog (x+x)). 
Channels 1 and 2 of the Babyface Pro have digitally controlled 
microphone preamps of the highest quality. The digital control offers a 
gain setting in steps of 1 dB within a range of 0 dB to +65 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. The current gain is displayed in dB beside the knob. 
Additionally a PAD can attenuate the input signal by 11 dB, to prevent 
overloads by hard driven microphones or high level line signals. This 
useful feature extends the gain range and increases the maximum input 
level from +8 dBu up to +19 dBu at the XLR input. 
Above the knob Gain the inputs can be set separately to provide 48V 
phantom power at the XLR sockets. Phantom power is required for 
condenser microphones. 
Input channels 3 and 4 are found as TS jacks on the right side of the Babyface Pro. These Hi-Z 
universal inputs have an input impedance of 470 kOhm. The input gain is controlled and per-
formed digitally and limited to 9 dB. An additional hardware-based reference level optimizes the 
signal to noise ratio. Choices are +4 dBu and -10 dBV. 
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 21). 
An  automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol 
with RME’s ASIO drivers and any ASIO 2.0 compatible program. When 'ASIO Direct Monitoring' 
has been switched on, the input signal is routed in real-time to the output whenever a recording 
is started (punch-in). 
9.7 Digital Recording 
Unlike analog soundcards which produce empty wave files (or noise) when no input signal is 
present, digital interfaces always need a valid input signal to start recording. 
Taking this into account, RME added a 
comprehensive I/O signal status display to 
the Babyface Pro, showing sample frequency, 
lock and sync status in the Settings dialog, 
and a status LED directly at the unit. 
The sample frequency shown in the Settings 
dialog 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 connec-
tion the Babyface Pro displays the current and external sample frequency. This parameter can 
then be changed in the application’s audio attributes (or similar) dialog.
