AUDIO EXPRESS FRONT PANEL OPERATION

MIXING WITH THE FRONT PANEL
CONTROLS
The Audio Express can operate as a mixer, and you
can use the knobs on the front panel to control the
mix. The mixer combines the signals of all inputs
and sends the mixed signal to an output pair, such
as the main outs. You can control the relative
volume of the inputs , as well as the overall volume
of the mix signal on output.
Figure 6-3: The Audio Express mixer takes all the input signals and
combines them to an output. You control the volume of each input
separately to produce a good mix.
Controlling the volume of inputs
Use the Input controls (Figure 6-1) to control the
volume of the Audio Express’s three input pairs.
Notice that you can mix the digital S/PDIF input
alongside the four analog inputs. Push to mute or
unmute the input.
Controlling the volume of the mix
Use the Mix volume knob (Figure 6-1) to control
the overall output volume of the mix.
Four separate mixes
The Audio Express provides a separate mix for
each of its four output pairs, as follows:
This means that for each Audio Express output
pair, the volume of each input can be completely
different than it is for other output pairs. This
allows you to create different mixes and send them
to separate destinations. For example, you could
send one mix to a PA system, and send a separate,
different mix to stage monitors. Yet a third mix
could be created for the headphones, and a fourth
mix could be sent to the digital outputs to a
recording device of some kind (or an effects
processor).
Choosing a mix to control
The Audio Express front panel controls only one
mix at a time. To choose which mix you are
controlling, push the MIX/VOL knob (Figure 6-4)
repeatedly. The current mix LEDs (Figure 6-4)
indicate the currently selected mix.
Figure 6-4: The Mix LEDs indicate which mix you are controlling with
the front panel.
Controlling pan
If a mix is selected and the volume (vol) LED is
illuminated as shown in (Figure 6-4), this indicates
that the front-panel knobs are currently controlling
each input’s mix volume. If you wish to control the
left-right panning of the input, push and hold the
MIX/VOL knob. Doing so causes the pan LED
(Figure 6-4) to illuminate. You can now use the
knobs to pan each mono input left or right. Like
volume, the pan setting for the input can be
different for each of the four mixes. Push the knob
to toggle between pan-center or pan-left/right.
