System Commisioning for Remote Volume Controls Procedure-
Systems fitted with wall mount volume control require careful commissioning to ensure that safe levels cannot be
exceeded at any wall control panel. The optional remote controls can only attenuate levels downward from the maximum
levels set on the PLC4.1 Controller .
1) Set all level controls on the PLC4.1 to minimum.
2) Set wall panel control(s) to minimum.
3) Set all FILTER SELECT switches to FULL FREQUENCY.
4) Plug the PLA305 amplifier into a 110vac wall outlet.
5) Set all wall panel controls to maximum.
6) Adjust sub level and master level wall panel controls to maximum.
7) Adjust MASTER LEVEL control to its mid position.
8) Select a channel (or zone) where the highest sound levels will be required.
9) Start the music source. Feed levels should be at mid position.
10) Carefully adjust the selected channel's LEVEL control to the desired maximum safe level. If an adequate level
cannot be achieved, check the signal source level and readjust if necessary .
11) If an adequate level still cannot be achieved, raise the MASTER LEVEL to a higher position. Readjust the channel
LEVEL to achieve the desired volume.
12) Set the three remaining channel LEVEL controls to their appropriate levels without adjusting the
MASTER LEVEL control.
13) Once the levels on the PLC4.1 have been set, all operator level changes will be made at the remote wall
control panel.
14) Switch FILTER SELECT switches to their DOWN position as required.
15) Adjust the SUB LEVEL control for a subwoofer sound level that is complementary with its associated main speakers.
16) Reinstall the security covers on the PLC4.1.
