User Operation
The ProMatrix Control Panel
The control panel is the interface between the user and the unit functions.
Since there are three channels (amp or preamp) and only one control panel,
the ProMatrix uses selector buttons, indicators and an alphanumeric display
to provide control of the overall functions. The information below will famil-
iarize you with the operation of the control panel.
The control panel typically shows the following information:
• The currently active amp/channel — the one that is currently under con-
trol panel control — by means of an indicator lamp.
• The currently active input — shown on the alphanumeric display and
indicator lamp.
• Input selection status — either automatic or manual selection
• The currently active control — VOL, BASS or TREB — which can be
adjusted by pressing the arrow buttons.
If the arrow keys are not touched for 5 seconds, the unit defaults to the
VOL control; you have to first select BASS or TREB to use these con-
trols.
When the ProMatrix is in User Mode, the user can perform the following
functions
• Apply power
• Select a channel
• Adjust volume and tone for all inputs on the selected amp/channel
• Manually select an input

To Apply Power to the ProMatrix Unit

To apply power, press the button labeled POWERon the control panel. or
on the wireless infrared remote controller.

To Select an Amp/Channel

In order to change the volume or tone for an amplifier channel, the
amp/channel must first be selected. To select, press the desired AMP but-
ton (AMP 1, AMP 2 or AMP 3). Its indicator will illuminate brightly. The cur-
rent input for that amp will appear on the alphanumeric display panel.
Once an AMP is selected, the user can adjust the VOL, BASS or TREB
control to the selected AMP.
