5. First Usage – Quick Start

5.1 Connectors and Front Panel

The front of the Fireface UC features instrument, microphone and line inputs, a stereo

line/headphone output, a rotary encoder with 7 segment display, and several status and MIDI

LEDs.

The Neutrik combo jacks of the

Mic/Line inputs can be used via

XLR and 1/4" TRS plugs. Both

inputs display overload (CLIP),

signal presence (SIG) and phan-

tom power (48V) via green, red

and yellow LEDs.

Inputs 3/4, INST/LINE, accept both a balanced line signal as well as an unbalanced instrument

signal via 1/4" TRS plug.

The rotary encoder serves to set the input and output levels directly at the unit. This is not only

useful in stand-alone operation, but for example also when setting up the monitor volume.

Pushing the knob changes the encoder from CHANNEL to LEVEL mode and back. Pushing the

knob for more than a second activates either the single channel or stereo setup mode.

The State LEDs (WC, SPDIF, ADAT) indicate a valid input signal separately for each digital

input. Additionally, RME's exclusive SyncCheck indicates if one of these inputs is locked, but

not synchronous to the others, in which case the LED will flash. See also chapter 9.8/16.2,

Clock Modes - Synchronization.

The red HOST LED lights up when the

Fireface UC has been switched on. It

operates as error LED, in case the USB

connection hasn't been initialised yet, or has

been interrupted (error, cable not connected

etc.).

The yellow MIDI LEDs indicate MIDI data

received or sent, separately for both inputs

and outputs.

Phones is a low impedance line output of highest quality. It provides a sufficient and undis-

torted volume even when used with headphones.

The rear panel of the Fireface UC features four analog inputs, six analog outputs, the power

socket, and all digital inputs and outputs.

SPDIF I/O coaxial (RCA): AES/EBU compatible. The Fireface UC accepts the commonly used

digital audio formats, SPDIF as well as AES/EBU.

ADAT I/O (TOSLINK):

The unit automatically

detects SPDIF or ADAT

input signals. The optical

output can operate as

ADAT or SPDIF output,

depending on the current

setting in the Settings

dialog.
