To Return to Auto Switching

User Operation

the current input was lowered by. This is because the levels set by the user are temporary and the ProMatrix always strives to maintain volume differences 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 and SEL INPUT appears on the display panel.

2.Press the desired input selector button (MIC A/B, AUX A/B/C/D). The AUTO LED and selected input LED will flash to indicate that auto- switching is off for this channel.

Note: You must return to auto-switching before manually selecting 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, both the AUTO and selected input LEDs will flash.

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

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.

When a higher priority input becomes active, ProMatrix changes to that input. If that input goes silent for more that approx. 16 seconds, the unit will fade in the next lower priority active input. (Mics in VOX mode take aprox. 4 seconds to switch back. In contact closure mode, the switchback is immediate.) One exception is the AUX D input which allows aprox 30 seconds of silence before switching back. This extra delay is provided for equipment, such Juke boxes that may have a considerable delay between music selections. If the extra delay is needed, simply give AUX D the desired priority level for the source connected to it. If the extra delay is not needed, leave AUX D as the lowest priority level or remove it from the priority list if it is not needed.
