RME Babyface Pro FS 24-Channel 192 Kilohertz Bus-Powered USB 2.0 Audio Interface

Four years ago the Babyface Pro again demonstrated RME’s absolute commitment to superior craftsmanship, not only in audio circuits and driver development, but also in mechanics. Created with the highest precision from a block of aluminum, this high-end portable interface incorporated newly designed analog and digital circuits. Its innovative energy saving technologies provided supreme fidelity with no compromises in level, noise or distortion.

Features:

+19/+4 dBu switch on the bottom adds a direct way to reduce the output level, improving SNR for sensitive active monitors, as well as avoiding distortion/overloads, and keeping TotalMix FX faders near 0 dB instead of high attenuations
Full SteadyClock FS circuit for ultralow jitter and high jitter immunity
3.5 mm TRS phones output power rises from 70 mW to 90 mW
THD of both phones outputs improved by up to 10 dB
Uses same output op-amps as ADI-2 Pro
Output impedance of 3.5 mm TRS lowered from 2 to 0.1 ohm
Mic inputs SNR improved from 112.2 to 113.7 dB
TRS line inputs SNR improved from 114 to 116 dB RMS (120 dBA)
THD line inputs improved by 8 dB
Latency improved by six samples on the AD side by new ADC (5 samples AD, 7 samples DA)
No increase in power consumption, despite new features
K-slot for theft protection
