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).
