Quick Start - RME Audio Fireface UC User Manual

Word Clock I/O (BNC): A push switch activates internal termination (75 Ohms). When termina-
tion is activated the yellow LED beside the switch lights up.
MIDI I/O: Provides two MIDI inputs and outputs via the included breakout cable.
USB 2.0: USB socket for connection to the computer.
POWER (switch): Turns the Fireface UC on and off.
Socket for power connection. The
included hi-performance switch
mode power supply makes the
Fireface operate in the range of
100V to 240V AC. It is short-
circuit-proof, has an integrated
line-filter, is fully regulated against
voltage fluctuations, and
suppresses mains interference.

5.2 Quick Start

After the driver installation (chapter 7 / 15) connect the TRS jacks or the XLR jacks with the
analog signal source. The input sensitivity of the rear inputs can be changed in the Settings
dialog (Gain/Level), assuring the highest signal to noise ratio will be achieved. Try to achieve an
optimum input level by adjusting the source itself. Raise the source's output level until the peak
level meters in TotalMix reach about –3 dB.
The analog line inputs of the Fireface UC can be used with +4 dBu and -10 dBV signals. The
electronic input stage can handle balanced (XLR, TRS jacks) and unbalanced (TS jacks) input
signals correctly.
The front's inputs signal level can be optimized using the Fireface's rotary encoder. A Signal
LED and a Clip LED help to find the correct level adjustment.
The Fireface's digital outputs provide SPDIF (AES/EBU compatible) and ADAT optical signals
at the corresponding ports.
On the analog playback side (the DA side), a coarse adjustment of the analog output level at
the rear jacks is available in the Settings dialog (Gain/Level/Line Out).
The output signal of channels 7/8 is available on the front. Their output level can be set using
the rotary encoder. This output is a very low impedance type, which can also be used to con-
nect headphones.
The Fireface UC remembers all settings, and loads these automatically when switched on. With
this, the Fireface UC can be used stand-alone after setting it up accordingly, replacing lots of
dedicated devices (see chapter 21).
