The compact Fireface UC has been uncompromisingly optimized for highest performance under Windows and Mac OS. Based on a newly developed RME Hammerfall core the Fireface UC provides revolutionary ultra-low latencies even with multiple channels. It uses two different firmware versions with different transfer methods to remove current restrictions of typical USB audio interfaces. The unit's operating mode Win or Mac can be changed directly at the unit at any time. Under Mac OS the Fireface's MIDI ports are class compliant, the operating system therefore automatically uses the included MIDI driver.

Under both Operating Systems the available latencies* are simply sensational. The smallest buffer offered under Windows has 48 samples, under Mac OS X 14 samples. With this RME provides a performance previously not available from USB audio interfaces.
