RME Fireface UCX II is a half-rack sized USB interface with up to 40-channels (8 x Analog I/O) and RME’s famous SteadyClock FS.
Compatible with Windows and Mac computers, Plug-and-Play technology guarantees a simple installation, even for the inexperienced user. Unique features like a well thought-out Settings dialog and an integrated routing solution provide quick, comfortable and efficient operation of this interface.
Fireface UCX II has two mic/line preamps in XLR combo configuration on the front panel, along with two digitally controlled line/instrument inputs, followed by a headphone jack, various control buttons, a display, and the main volume knob. At the rear is a set of ten analogue balanced line inputs and outputs, MIDI I/O, ADAT I/O, AES/EBU and SPDIF I/O, USB 2.0 as well as a switchable word clock I/O.
With SteadyClock FS, Fireface UCX II features the latest clock and jitter rejection technology from RME. Based on a femtosecond clock, SteadyClock FS reduces the intrinsic jitter when converting from and to analogue over all digital formats to a new all-time low.
Fireface UCX II comes with the TotalMix FX DSP mixer offering comprehensive routing and monitoring options, as well as the DIGICheck Analyzer allowing to measure and analyse the digital data feed in both directions with maximum precision. TotalMix FX can completely replace an external mixer, enabling the creation of multiple latency-free monitor mixes with EQ, Dynamics, Reverb and Delay for any outputs, incl. main monitors and headphone mixes for musicians.
