RME Babyface Pro FS 24-Channel 192kHz USB Audio Interface Bundle with Ferrofish Pulse8 AE 8x8 AD/DA Converter

SKU CH-FZHK-X6SG7

24-channel USB audio interface with 8×8 AD/DA converter, 192 kHz operation and 76 dB gain range in 1 dB steps

  • +19 / +4 dBu switch protects sensitive monitors from overload
  • SteadyClock FS circuit delivers lowest jitter and highest immunity
  • 5 mm headphone output reaches 90 mW with 0.1 Ohm impedance
  • Mic preamp SNR hits 113.7 dB with 76 dB gain range
  • Bundle adds 8-channel AD/DA conversion via ADAT for 24-channel I/O

Portable 24-Channel 192kHz Interface

The RME Babyface Pro FS is a bus-powered USB audio interface that delivers 24 channels at up to 192 kHz. It is built from a precision-machined aluminium block and includes two digitally controlled preamps with 76 dB gain range in 1 dB steps and switchable 48 V phantom power. The bundle adds a Ferrofish Pulse8 AE 8x8 AD/DA converter connected via ADAT for expanded I/O.

For Mobile Recording and Fixed Studios

This suits engineers who need a compact, high-fidelity front end for location work or a permanent desk setup. The SteadyClock FS circuit provides low jitter and high jitter immunity, while the +19/+4 dBu output switch helps keep TotalMix FX faders near unity with sensitive monitors. Buyers requiring more than eight analogue inputs without adding external converters should look elsewhere.

Build Integration and Expandability

The interface draws power from the USB bus, freeing a mains socket and simplifying mobile rigs. Two independent headphone outputs — 3.5 mm TRS and 6.3 mm TRS — each have dedicated driver stages; the 3.5 mm jack now delivers 90 mW with 0.1 Ohm output impedance. ADAT I/O on the Babyface and the Pulse8 AE allows the eight converter channels to be added without using extra USB ports.

Questions about this item

Does the Babyface Pro FS need an external power supply or will my laptop's USB port run it?

The interface is bus-powered over USB, so a standard USB port on your computer supplies all the power it needs.

If I keep my older ADAT gear, can the Pulse8 AE's eight channels of AD/DA connect straight to the Babyface's optical ports?

Yes, the Pulse8 AE provides eight channels of AD/DA conversion over ADAT, which plug directly into the Babyface Pro FS optical I/O for 24-channel total I/O.

How do I verify the headphone outputs are performing at the updated 90 mW / 0.1 Ω spec after setup?

Open TotalMix FX, route signal to the 3.5 mm TRS jack, and confirm clean drive with low-impedance headphones — the hardware now delivers 90 mW at 0.1 Ω output impedance.
