RME Fireface UCX II 40-Channel USB-B Audio/MIDI Interface

RME Fireface UCX II 40-Channel USB-B Audio/MIDI Interface

The RME Fireface UCX II is a professional‑grade USB audio interface designed for studio recording, live production and mobile rigs. Able to handle up to 40 channels (20 in / 20 out) in a compact half‑rack format, it combines ultra‑low latency, class‑leading clocking, and full stand‑alone operation for both computer‑based and off‑computer workflows. With two reference‑quality mic/line preamps, full analog and digital I/O (ADAT, AES/EBU, S/PDIF, word clock, MIDI), and built‑in mixer/FX via TotalMix FX, the Fireface UCX II offers exceptional flexibility for engineers, musicians and content creators

Key Features

• Massive I/O in a compact chassis: up to 20 inputs and 20 outputs (analog + digital) in a half‑rack unit.
• Two high‑performance mic/line preamps on the front panel (XLR/¼″ combo) plus two front panel line/instrument inputs.
• 24‑bit / 192 kHz AD/DA conversion for pristine audio quality.
• Digital I/O: ADAT optical (in & out), AES/EBU and S/PDIF coax, word clock I/O for external sync.
• Class‑Compliant mode (i.e., plug‑and‑play) for iPad/USB setups (with limited features).
• DC‑coupled line outputs – meaning it can output control voltages (CV/Gate) for modular synth integration.
• Integrated stand‑alone recording: via “DURec” you can record all inputs/outputs directly to a USB drive (no computer required).
• Powerful DSP‑based mixer/routing engine: TotalMix FX lets you route any input to any output, create multiple monitor mixes, add onboard effects (EQ, dynamics, reverb, delay).
• Ultra‑stable clocking: “SteadyClock FS” technology reduces jitter to femtosecond levels, improving conversion accuracy and digital integrity.
• Metal, rugged build and compact design – ideal for both studio and mobile use.
