Essential Information About the RME Babyface Pro FS Audio Interface
- SteadyClock FS derived from the ADI-2 Pro for minimal jitter, a solid stereo image, and reference 24-bit/192 kHz conversion.
- Optimized headphone monitoring: power increased to 90 mW, THD reduced by up to 10 dB, and output impedance of 0.1 ohms to drive in-ear monitors and sensitive headphones noise-free.
- High-gain preamps up to 70 dB, mic S/N ratio at 113.7 dB, and line inputs at 116.3 dB (120 dBA) for clean and dynamic recordings.
- Pro workflow and flexibility: 12 I/O, ADAT/SMUX or optical S/PDIF, MIDI via breakout cable, TotalMix FX, class compliant mode, and USB bus-powered.
The Babyface Pro "FS": RME's Icon Upgraded
Four years after the original Babyface Pro, RME takes its best-selling portable interface further. The Babyface Pro FS retains the machined aluminum chassis and elevates the clock and conversion to the "FS" standard. The +19/+4 dBu level switch optimizes the signal-to-noise ratio with sensitive monitors, while the new ADCs reduce conversion latency to 5 samples in AD and 7 in DA, enabling more responsive headphone monitoring without extra power consumption.
Who Is It For? Mobile Creators, Home Studios, and Traveling Engineers
Compact, robust, and USB-powered, this interface targets traveling artists, podcasters, streamers, and demanding sound engineers. RME drivers and TotalMix FX ensure exemplary stability in multitrack recording, low-latency streaming, and stage monitoring on both Mac and PC.
Next-Generation Conversion, Latency, and Monitoring
SteadyClock FS and Sonic Consistency
The "FS" clock maximizes jitter immunity for tight lows, precise transients, and a stable stereo image, including when externally synchronized via optical input. Paired with 24-bit/192 kHz converters, it guarantees consistent and reliable playback.
Versatile Preamps and Refined Inputs
The mic preamps offer up to 70 dB gain with attenuator, overload protection, and 48 V phantom power. The line/instrument inputs on 6.3 mm jacks benefit from an improved S/N ratio of 116.3 dB and an 8 dB reduction in THD, capturing DI, synths, and drum machines with wide dynamic range.
Calibrated Outputs and Controlled Headphone Monitoring
Two XLR outputs and two headphone outputs with dedicated impedances use the same operational amplifiers as the ADI-2 Pro. Increased power (90 mW) and 0.1-ohm impedance ensure clean driving of modern headphones. The +19/+4 dBu switch helps keep faders near 0 dB in TotalMix FX.
Comprehensive Connectivity and Mobile Workflow
Depending on needs, the optical port handles ADAT with SMUX or S/PDIF. MIDI is routed via a breakout cable, class compliant mode allows driverless operation, and standalone functionality with the K-slot secures sessions on the go.
