RME Fireface UCX II: The Ultimate Compact Audio Interface for Professional Studio and Live Use

The RME Fireface UCX II redefines compact audio interfaces with a feature-rich design and unmatched connectivity. Marking RME’s 25-year anniversary, this 9.5” rack-mountable interface offers 40 input/output channels and integrates a quarter-century of RME innovations, making it an ideal solution for flexible studio and live audio setups. The Fireface UCX II provides 20 recording and 20 playback channels, advanced SteadyClock FS technology, top-tier preamps, USB direct recording, and full stand-alone operation, combining freedom and flexibility for a premium audio experience.

Direct USB Recording with DURec

RME’s unique DURec (Direct USB Recording) feature allows for standalone recording of all I/O channels directly to a USB storage device. This independent recording capability bypasses the need for a computer, enabling field recordings, concert captures, rehearsal tracking, or playback of live recordings for virtual soundchecks. Powered by the UCX II’s internal DSP, DURec is versatile and ideal for mobile setups.

SteadyClock FS: Ultra-Precise Clocking

The Fireface UCX II integrates RME’s cutting-edge SteadyClock FS technology, reducing self-jitter to an exceptionally low level and ensuring high-accuracy clocking in all clock modes. This femto-second clocking system provides superior jitter suppression for clean and accurate sound, essential for studio-grade audio fidelity, especially in digital recording environments.

TotalMix FX & DigiCheck

Included with the Fireface UCX II is RME’s TotalMix FX, a powerful DSP-based mixing and monitoring tool with flexible routing options. The TotalMix Remote allows remote control over all aspects of TotalMix FX on a host device, including iPads, for convenient management. Additionally, DigiCheck, RME’s advanced metering and analysis software, enables precise monitoring and analysis of digital audio streams, offering a professional suite for testing and measuring audio data.

Front and Rear Connectivity for Maximum Flexibility

The UCX II provides extensive connectivity options for versatile setups. On the front, the interface includes two XLR-combo mic/line inputs, two line/instrument inputs, a headphone output, and essential controls. The rear panel offers ten analog balanced line inputs/outputs, MIDI I/O, ADAT I/O, AES/EBU and SPDIF I/O, USB 2.0, and switchable Word Clock I/O. These options make the Fireface UCX II a perfect choice for any audio production environment, accommodating a wide range of devices and configurations.
