User Operation
the current input was lowered by. This is because the levels set by the user
are temporary and the PM-3180 always strives to maintain volume differ-
ences set by the preset programming. Typically, this will only occur when
the inputs or limits are set vastly different for the inputs assigned to an amp
channel. The same applies to the tone controls where the amp tries to
maintain the EQ differences.
To Select a Specific Input
The amplifier monitors active inputs and, based on the default or installer-
created priority table, automatically switches the proper input for each chan-
nel. You can override the priority switching feature to select a specific input.
1.
Press the AUTO button. Its indicator LED will flash.
2.
Press the desired input selector button (MIC A/B, AUX A/B/C/D). The
AUTO LED will flash to indicate that auto switching is off for this chan-
nel.
Note:
You must return to Auto-switching before manually select-
ing another input.
Note:
If one amp is manually selected but the current amp is in
Auto-switch mode, the AUTO indicator will flicker to indicate that
another channel is under manual control. When the manually
selected amp is again made current, the AUTO LED will flash.
To Return to Auto Switching
Make the amplifier under manual control the current amp by pressing the
appropriate AMP button.
Press the AUTO button. The current input (based on priority) will appear on
the display and its indicator LED will light. The AUTO LED will light steady.
Important Operational Notes
• Microphones may need to be configured through the Program Mode in
order to operate correctly.
• When a microphone becomes active (through Vox or contact closure),
the current Aux input will be muted to a preset (Aux Mute function)
level. No input switching is allowed when the Aux mute is active.
