Quick Start - RME Audio Fireface UCX User Manual

Word Clock I/O (BNC): Termination for the Word Clock input (75 Ohms) can be activated in the
Settings dialog.
MIDI I/O: Provides two MIDI inputs and outputs via the included breakout cable.
Remote. Mini-DIN. Connector for the optional remote controls with Volume, Store, Dim and
Recall functions.
USB 2.0: USB socket for connection to the computer.
FW 400. 6-pin FireWire socket for connection to the computer.
POWER (switch): Turns the Fireface UCX 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 inputs with the
analog signal source. The input sensitivity of the rear inputs can be changed in TotalMix (Input
Channel Settings, Level), assuring the highest signal to noise ratio will be achieved. Also 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 UCX 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 gain value.
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 TotalMix (Output Channel Settings, Level).
The output level of channels 1 to 8 is also available on the front via the rotary encoder. Output
7/8, called Phones, is a very low impedance type, which can also be used to connect head-
phones.
The Fireface UCX remembers all settings, and loads these automatically when switched on.
Additionally the current state can be stored in and loaded from 6 different memory slots, called
Setups. With this, the Fireface UCX can be used stand-alone after setting it up accordingly,
replacing lots of dedicated devices (see chapter 26).
