RME Babyface Pro FS

The RME Babyface Pro FS is a compact USB audio interface with an aluminium housing and physical controls for recording and monitoring. Two balanced XLR mic/line inputs are joined by two unbalanced line/instrument inputs, allowing microphones and instruments to be connected without treating the headline channel count as a count of microphone sockets. Balanced XLR main outputs feed monitoring equipment, while headphone connections provide personal listening.

The computer connection uses USB 2.0, and supported operation extends up to 192 kHz. Its optical input and output can carry ADAT with SMUX support or S/PDIF, depending on the session configuration. RME’s twenty-four-channel headline combines input and output capacity and includes digital channels; the unit does not have twenty-four analogue inputs.

TotalMix FX supports audio routing and monitor mixing, with onboard effects available in the monitoring workflow. The FS model includes SteadyClock FS and an output-level switch for the balanced main outputs. USB bus power supports portable use with suitable computer ports, while actual channel availability depends on sample rate and the connected digital equipment.
