Windows or Mac
The Firface UC 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 impressive. 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.
Integrated DSP Mixer
All inputs and outputs can be freely mixed, routed and distributed with RME's MIDI remote controllable TotalMix software where up to 9 totally independent stereo submixes can be set up. All the output channels and every submix channel can be recorded directly and without external cable loops. The DSP based hardware calculates RMS and Peak levels for all channels without causing any significant CPU load.
Inputs and Outputs
Eight analog inputs and outputs (all balanced, except outputs 7/8) with software controlled reference levels (-10 dBV, +4 dBU, Lo/HiGain), realised discretely in the analog domain, ensure the highest dynamic range and fidelity. Inputs 5 to 8 on the rear feature RME's proven level references, -10 dBV, +4 dBu and Lo Gain can be selected in the settings dialog, equivalent to +2 dBV, +13 dBu and +19 dBu for digital full scale. The same applies to the balanced rear outputs 1 to 6. The hi power phones output offers high volumes even with low impedance headphones.
One ADAT I/O provides digital connection to mixers and converters. In combination with an ADI-8 DS/QS or OctaMic II, there are up to 16 analog inputs (respectively 12 @ 96 kHz). The coaxial SPDIF I/O (up to 192 kHz) is fully AES/EBU compatible. SPDIF can also be accessed through the optical I/O.
A Word Clock input and output plus two MIDI I/Os (special breakout cable included) complete the list of features and turn the Fireface UC into an entire audio system of the highest quality.
The Fireface UC features 2 balanced mic inputs with a digitally controlled input stage, individually switchable 48 V phantom power and Neutrik Combo connectors for XLR and TRS (that can also be used as additional line inputs). A pre-amplification of up to 65 dB (adjustable in 1 dB-steps over a range of 55 dB), exceptional EIN (Equivalent Input Noise) performance even at low pre amplification settings, and extremely low THD+N allow these preamps to surpass many reference devices.
All level settings are 100 reproducible and can also be comfortably adjusted by software. Inputs 3 and 4 are flexible universal balanced inputs that operate exactly like inputs 5 to 8 on the rear and can be adjusted to accept standard studio input levels (+4 dBu, LoGain). The input impedance can be switched from line (10 kOhm) to instrument (470 kOhm), and offers an additional analog input amplification of up to 18 dB in steps of 0.5 dB.
