Sleek Desktop Interface with Femtosecond Clock

The RME Babyface Pro FS is a powerful yet highly portable, bus-powered USB audio interface housed in a rugged, low-profile aluminum chassis. Its clean desktop design offers intuitive control while delivering reference-quality recording through two digitally controlled microphone preamps and comprehensive analog, digital, and MIDI connectivity for seamless studio integration.

Compact 12-in/12-out Powerhouse

Despite its compact size, the Babyface Pro FS provides a full 12-in/12-out configuration, including mic/line/instrument inputs, balanced line outputs, ADAT/SPDIF I/O, MIDI connectivity, and dual headphone outputs. Clear onboard metering with peak and RMS calculation ensures precise level control, all while maintaining a simple and elegant desktop footprint.

Ultra-Stable SteadyClock FS Technology

Featuring the same SteadyClock FS circuit found in RME’s flagship ADI-2 Pro, the Babyface Pro FS achieves extraordinarily low self-jitter, measured in femtoseconds. An upgraded analog PLL circuit and low-phase-noise quartz crystal provide ultra-stable clocking that exceeds typical PLL performance, delivering exceptional clarity and accuracy across all sample rates.

TotalMix FX and Expanded Performance Enhancements

RME’s TotalMix FX engine supplies a fully flexible 288-channel mixer with 46-bit internal resolution, offering latency-free monitoring, EQ, low-cut filtering, reverb, and echo. Additional hardware refinements include improved signal-to-noise ratios, reduced distortion, increased headphone output power, lower output impedance, and reduced latency, all achieved without increasing power consumption. The Babyface Pro FS also includes a premium plug-in bundle and both USB-2 and USB-C cables for immediate professional use.

What RME Says...

• Precision Engineering and Build Quality
• Precision-milled aluminum housing
• Low-profile, rugged desktop design
• Optimized mechanical stability for mobile and studio use

The Babyface Pro FS is crafted from a solid block of aluminum, reflecting RME’s uncompromising approach to mechanical precision and durability. Its robust yet compact housing ensures long-term reliability while maintaining a clean, professional desktop footprint ideal for both studio and mobile recording environments.

Enhanced Analog and Digital Circuitry

• Newly redesigned analog and digital circuits
• No compromise in level, noise, or distortion
• Energy-efficient design

RME has refined every stage of the Babyface Pro FS signal path, delivering improved audio fidelity without increasing power consumption. These circuit enhancements result in superior clarity, dynamic range, and consistency across all inputs and outputs.

Advanced Output Level Control

• +19 / +4 dBu output level switch
• Improved signal-to-noise ratio for sensitive monitors
• Reduced risk of overload and distortion

The rear-mounted +19 / +4 dBu switch provides a direct way to optimize output levels for active monitors. This feature improves SNR, avoids clipping, and allows TotalMix FX faders to remain near unity gain for optimal resolution.

SteadyClock FS Digital Clocking

• Full SteadyClock FS circuit
• Femtosecond-level jitter performance
• Exceptional jitter immunity in all clock modes

Borrowed from the ADI-2 Pro FS, SteadyClock FS technology delivers reference-class digital clocking. This ensures maximum timing accuracy, improved stereo imaging, and pristine digital-to-analog conversion across all sample rates.

High-Power, High-Fidelity Headphone Outputs

• Dual headphone outputs (TRS and 3.5 mm)
• Up to 90 mW output power
• Ultra-low 0.1 ohm output impedance

The Babyface Pro FS features independent driver stages for each headphone output, ensuring optimal performance with both low- and high-impedance headphones. Improved THD performance and ADI-2 Pro-grade op-amps deliver pristine monitoring quality.

Improved Mic and Line Inputs

• Digitally controlled mic preamps with 76 dB gain range
• Relay-driven PAD for overload protection
• Improved SNR and reduced THD

Two high-performance microphone preamps provide individually switchable 48V phantom power and 1 dB gain steps. Enhanced EIN performance and improved line input specifications ensure clean, detailed capture for microphones, instruments, and line-level sources.

Comprehensive Connectivity and Expansion

• ADAT / SPDIF optical I/O with SMUX support
• Instrument, line, and Hi-Z inputs
• MIDI I/O via included breakout cable

Despite its compact size, the Babyface Pro FS offers extensive connectivity. Optical I/O enables up to 12 inputs and 12 outputs with an external converter, while flexible analog and MIDI connections make it suitable for studio and live multitrack setups.

TotalMix FX and RME Driver Stability

• TotalMix FX real-time DSP mixer
• Latency-free EQ, reverb, and echo
• Industry-leading USB driver stability

TotalMix FX provides unmatched routing flexibility with independent submixes, Control Room functions, and onboard DSP processing. Combined with RME’s legendary USB drivers and ongoing software support, the Babyface Pro FS delivers rock-solid performance on both Mac and Windows systems.
