25. Operation and Usage
25.1 General
The Fireface UCX has an internal memory to permanently store all configuration data. The data
is stored directly after any change, and is loaded at power-on. Saved settings are:
Settings dialog
Sample rate, clock mode Master/Slave, configuration of the channels and the digital I/Os.
TotalMix
The complete mixer state.
This also improves the clock situation immediately after power-on, avoiding wrong clocking and
noise disturbances in a complex setup, caused by wrong synchronization.
While the three rotary encoders and the clear colour display of the Fireface UFX are missing in
the Fireface UCX, it still uses the same engine inside, and subsequently has all the stand-alone
features found in the UFX. The full Mackie Protocol and MIDI remote support makes it possible
to use the unit even without connected computer, still being able to change many parameters.
Additionally the internal memory can permanently store six more states of the unit. Therefore
the Fireface UCX can transform into totally different devices by the simple click of a button.
Finally, as TotalMix can also be controlled via MIDI (see chapter 30.6, Stand-Alone MIDI Con-
trol), the examples shown below are really useful applications that you should keep in mind.
25.2 Front Panel Operation
The knob on the front, a so called rotary encoder, serves to set the input gains and output vol-
umes directly at the unit. The encoder operates either in CHANNEL or in LEVEL mode. Pushing
the knob changes between these modes. The currently active mode is indicated by a green
LED. Pushing the knob repeatedly gives quick access to PH (Phones) for a fast access of the
main volume control.
In CHANNEL mode, selection of the desired channel is done by turning
the knob. The following strings will be shown in the display:
i.1 to i.4 Mic input 1 up to instrument/line input 4
L.1 to L.6 Line output 1 up to line output 6
PH Phones (line output 7/8)
SP SPDIF output
A.1 to A.8 ADAT output 1 up to 8
SU Load Setup
i.1 / i.2
The gain of the two microphone inputs 1/2 can be defined in the range of 10 dB up to 65 dB in
steps of 1 dB. Additionally the setting 0 dB is available. The gain change is performed in the
analog domain.
i.3 / i.4
The gain of the two instrument/line inputs 3/4 can be defined in the range of 0 dB up to 12 dB in
steps of 0.5 dB. The x.5 dB values are signalled by a dot to the right. The gain change is per-
formed in the digital domain.
L.1 to L.6, PH, SP, A.1 to A.8
The output levels of these outputs can be defined in the range of +6 dB down to –58 dB in steps
of 1 dB. Values below 0 dB are indicated by a dot to the right. The lowest value is maximum
attenuation (mute, shown as oo.). The gain change is performed digitally by TotalMix.
