The result of this effort is one of RME's most successful products. The Fireface UC continues the tradition of RME's tremendously successful compact interfaces, reinventing an already near-perfect product, improving existing features and characteristics as well as adding sophisticated new ones.

Contained in a half-rack unit, the UC is more powerful than most 19 inch units. All in all, the Fireface UC is the new compact-sized dream interface, created with care for every detail and a new premium solution for any desktop and live use, without compromising in sound, stability and ulta-low latency operation.

The UC provides 36 channels of audio - 18 I/Os. All channels can be used at the same time. Up to 8 analog and 10 digital channels can be recorded onto 18 seperate tracks. All outputs can be used for ASIO Direct Monitoring purposes.

The UC is equipped with an A/D and D/A high-performance converter design, all I/Os operate at up to 192kHz. In the best RME tradition, the UC converters and preamps have no characteristic 'sound' of their own, they neither add nor remove anything, but capture the original signal just as it is. There are Low Latency converters, pro-level support and a SteadyClockwhich finalises the state-of-the-art AD/DA conversion, even when clocking to an external digital source.

The UC provides two high-end mic and instrument preamps, built right into the front. The outstanding preamp design boasts extremely low distortion, excellent signal-to-noise ratio and a perfectly flat frequency response.

Each channel can be individually switched to 48V phantom power. LEDs for signal, clip and activated phantom power give a complete overview on the unit's status.

A complete effects engine comes in the form of the DSP-based TotalMix mixer, fully supporting independent routing and mixing of all 18 input and playback channels to all 18 physical outputs. The improved Control Room allows you to cue studio monitors and phones for quick listening to other outputs. Trim Mode adjusts the volume for all routed signals of a channel, and it's packed with other features such as and Extended Matrix, Expandable Channel View and four Mute, Solo and Fader groups each.
