Overview
RME machined the Babyface Pro FS from a block of aluminum, a portable USB interface with redesigned analog and digital circuits and a SteadyClock FS clock for low jitter. TotalMix FX handles the routing and mixing.
Build quality, clock accuracy and flexible routing set this interface apart for mobile and studio work. Compared with the earlier Babyface Pro, the listing points to improved headphone power and input noise, but it states no warranty and no dimensions.
Who it's for
Mobile recordists and studio users who need many channels, strong clocking and sensitive-monitor support. Casual users who only need one or two inputs may find the routing software more than they need.
Pros and cons
- Machined aluminum housing
- SteadyClock FS low-jitter circuit
- TotalMix FX routing software
- Output level switch for sensitive monitors
- Warranty terms not listed
- Dimensions not given
Performance notes
A clock with low jitter holds converter timing steady, which matters for clean conversion. The output level switch lowers the signal that reaches sensitive active monitors, improving signal-to-noise and avoiding overload. Separate driver stages for the two headphone sockets let low and high impedance headphones both get a matched drive, per the description.
