POWERLINX PLC4.1 CONTROLLER
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.
