This unique audio system is capable of transferring analog and digital audio data directly to Windows and Mac computers. The latest Plug and Play technology guarantees a simple installation, even for the inexperienced user. Numerous unique features like a well thought-out Settings dialog and an integrated routing solution realize a quick, comfortable and efficient operation of the Fireface UCX II. The Fireface UCX II houses 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 the SteadyClock FS, the 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.
