The Babyface Pro FS is RME's flagship compact audio interface, built for professionals who demand studio-grade performance in a portable form factor. Machined from a solid block of aluminium, it combines exceptional analog circuitry, ultra-low latency, and a comprehensive I/O set, all powered over USB with no external power supply needed.

Build Quality

Unlike the plastic shells found on most interfaces at this price point, the Babyface Pro FS is precision-manufactured from a single block of aluminium. It is built to withstand the rigours of regular travel and daily studio use without any compromise to internal components or connectors.

Audio Performance

The Babyface Pro FS delivers specifications that rival dedicated studio hardware. Mic input SNR reaches 113.7 dB, while the TRS line inputs achieve 116.3 dB (120 dBA). THD on the line inputs has been improved by 8 dB over the previous generation, and the AD converter runs at just 5 samples latency, with 7 samples on the DA side.

Headphone Outputs

Two dedicated headphone outputs, a 6.3mm TRS jack and a 3.5mm TRS jack, run completely separate driver stages so they can each be optimised independently for low and high impedance headphones. The 3.5mm output delivers 90 mW with an output impedance of just 0.1 Ohm, using the same op-amps as RME's flagship ADI-2 Pro.

Preamps and Inputs

The two XLR mic inputs feature digitally controlled preamps with a 76 dB gain range (adjustable in 1 dB steps), individually switchable 48V phantom power, and a relay-driven PAD for overload protection. Inputs 3 and 4 are instrument/line jacks (1 MOhm impedance), so you can plug a guitar straight in without a DI box.

SteadyClock FS

The Babyface Pro FS incorporates RME's full SteadyClock FS circuit, the same technology used in the ADI-2 Pro FS, providing jitter suppression exceeding 50 dB at 2.4 kHz across all clock sources. This translates to a wider, more accurate stereo image and greater clarity throughout a mix.

TotalMix FX

Every Babyface Pro FS ships with TotalMix FX, RME's FPGA-based real-time mixing software for Windows, Mac, and iOS. It allows fully independent routing of every input and playback channel to any output, with per-channel 3-band parametric EQ, reverb, and echo effects. TotalMix Remote extends this via Wi-Fi, letting you control the interface from a tablet anywhere in the studio.

Drivers and Long-Term Support

RME develops its own driver stack rather than relying on third-party chipsets, which means driver updates follow new OS versions quickly, including Apple Silicon support. RME's track record of long-term software support means buying one is a long-term investment rather than a product that becomes obsolete within a few years.
