The last portable interface you will ever need!

Meet the world’s most versatile, portable and expandable audio interface that delivers the best quality audio, 
wherever your creative journey takes you.

The 2nd generation of the Babyface Pro improves all elements – again:
Sound quality, MicPres, Instrument inputs, lowest-noise Headphone/IEM outs and ultra-low latency.
All elements are industry-leading representatives of its kind – still combined in a fully bus-powered mobile interface, working with all features at the same even on legacy USB ports!

The Babyface Pro FS not only provides RME´s new SteadyClock FS pro audio clock with FemtoSecond accuracy. The ultra-compact box inherits now the same highest quality analog conversion and uses the same headphone preamp technology output op-amps as ADI-2 Pro now. It comes with an USB-C cable and provides a newly K-Slot for theft protection.SPECSBabyface Pro FS
