The front of the Fireface UCX features instrument, line and microphone inputs, a stereo
line/headphone output, a rotary encoder with push functionality, a 7 segment display, and sev-
eral 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 also when adjusting the monitor volume. Pushing the knob
changes the encoder from CHANNEL to LEVEL mode and back. Pushing the knob repeatedly
gives quick access to PH (Phones) for a fast access of the main volume control.
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 UCX has been switched on. It
operates as error LED, in case the USB or
FireWire 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 UCX 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 UCX 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.
