RME Fireface UCX II USB Audio Interface (Price on request)

Professional Standard in a Half-Rack Frame

The RME Fireface UCX II is a power-dense 40-channel interface designed for elite audio performance in any environment. It integrates flagship features—like reference-grade conversion and standalone recording—into a portable, rugged housing. This is the definitive choice for mixing engineers, mobile recording artists, and modular synth enthusiasts who demand RME's legendary stability without the full-rack footprint.

Femtosecond Precision Clocking
The UCX II features SteadyClock FS, the same reference-class technology found in RME’s ADI-2 Pro converter. It reduces jitter to a femtosecond level—a quadrillionth of a second—ensuring your recordings possess incredible depth and a perfectly defined soundstage. This means your AD/DA conversion remains transparent and artifact-free across all digital formats.

Hardware-Based Standalone Recording
Integrated DURec (Direct USB Recording) allows you to capture all 40 channels directly to a USB thumb drive or hard drive up to 2TB. Because it is powered by internal DSP, it operates independently of a computer, making it a reliable field recorder or a redundant backup for live performances. You can even use it for virtual soundchecks or mobile jam sessions without a laptop in sight.

Modular Synergy via DC-Coupling
This interface serves as a bridge for hybrid studios by featuring fully DC-coupled outputs. Unlike traditional interfaces that filter out extreme low frequencies, the UCX II can send stable control voltages (CV) or Gate information to modular synthesizers like Eurorack. This allows you to automate hardware pitch, filters, and LFOs directly from your DAW.
