RME Fireface UCX II — 40-Channel USB Audio Interface

The RME Fireface UCX II is a 40-channel advanced USB audio interface packing studio-grade conversion, a full DSP mixer, and standalone recording into a half-rack enclosure. SteadyClock FS femtosecond clocking delivers reference-class jitter rejection across all digital formats. Offering 20 inputs and 20 outputs, this model provides high I/O density for project studios and mobile rigs.

DURec Standalone Recording and DC-Coupled CV/Gate Outputs

The integrated DURec recorder captures all 40 channels directly to USB storage without a computer. All line outputs are DC-coupled for sending control voltages and Gate signals to Eurorack modular synthesizers. TotalMix FX provides latency-free routing, EQ, dynamics, reverb, and delay on every channel.

Analog Performance — 24-bit / 192 kHz Conversion

Two front-panel digitally controlled microphone preamps offer 75 dB of gain in 1 dB steps, with two line/instrument inputs adding 24 dB for DI use.

• Bit Depth: 24 bit
• Sample Rate: 192 kHz
• Users get 4 preamps, consisting of two mic/line XLR combo preamps plus two line/instrument inputs.
• Phantom Power: Yes
• Signal-to-Noise Ratio: 112 dB RMS unweighted / 115 dBA

Digital I/O — ADAT, AES/EBU, S/PDIF, and Word Clock

AES/EBU, coaxial S/PDIF, and ADAT optical operate simultaneously, so the full 40-channel count is usable without trade-offs.

• ADAT: Yes — 1 x TOSLINK, 8 channels @ 48 kHz
• AES/EBU: Yes — transformer-balanced XLR
• S/PDIF: Yes — coaxial RCA
• MADI: No
• Word Clock: BNC I/O — switchable 75 Ohm termination
