MUTE
1) Un-assign Mic/Line Input signal and muting from the Zone
Output (restaurant). See Modifications on pg. 4. This allows
‘paging’ to occur only in the Main Output (lounge).
2) Connect Zone Output to the input of the amplifier driving the
restaurant speakers.
3) Connect Main Output to the inputs of the amplifier driving the
lounge speakers.
4) Connect the ‘paging’ microphone to the Mic/Line Input, with
the push-to-talk switch wired across the ‘Mute’ & ‘Gnd’
terminals. This allows switch-activated ‘page-over’ muting.
5) Connect the stereo line-level program sources to Inputs 1~4.
6) Adjust Level 1~4 (reduce level only on inputs which are
higher than the others).
7) Adjust Main Level, Zone Level, and Limit Threshold for
desired maximum levels.
8) Set Trim & Pad (+10 LED flash only on peaks). Adjust Mic
Level for desired paging level.
9) Connect an optional Controller to the Remote terminals.
Mount the Controller in a location to accept push-button and/or
infrared commands.
