Remote Control – PL-12 Wall Plate 
The optional Allen & Heath PL-12 ‘intelligent’ wall plate provides 
remote control of zone source selection and level. Full setup and 
operating instructions are detailed in the PL-12 user guide. The 
following provides an overview of its capability. 
Control A rotary level control provides 32 steps from fully off to 
fully on. Up/down keys toggle through the available sources with 
LEDs to indicate which source is active. An infra-red detector senses 
the optional PL-5 hand held remote if it is used. 
CAT5 cables A standard CAT5/RJ45 cable connects between the 
ZONE REMOTE port and the first PL-12 wall plate. Another cable 
connects from the first wall plate to a second if both zones require 
remote control. The control for both zones is passed down a single 
CAT5 cable. This can be convenient for cable installation and for 
situations where one remote is used to control both zones. 
Zone selection A jumper plug on the wall plate circuit card sets 
which zone to control. Each zone can be controlled by one plate 
only. However, you can set one plate to control both zones. 
Setup menu options The PL-12 presents the installer with many 
setup options to satisfy the custom requirements of the application, 
shown in the table here. These are accessed using setup mode. 
Wired switch options Two switch options are available at the 
PL-12 wall plate. One switches operating mode for zone 2 control to 
follow zone 1, convenient for room combining situations where a 
divider screen is fitted with a switch to toggle mode. This switch 
should be wired to the first wall plate. Another set of contacts can be 
wired to a remote switch to disable the wall plate when it should not 
be used by the operator. 
PL-5 infra-red controller The optional hand held controller may 
be used with the IR detector on the PL-12 wall plate for wireless zone 
level control and source selection. It provides additional functions 
including direct source selection, a source mute switch and a preset 
store/recall system. 
Working with presets The PL-5 hand held controller allows the 
storing and recall of up to 4 presets of level, source selection and 
zone 2 follow 1 setting. The installer can store these during 
installation, then disable store to prevent them being overwritten by 
the operator.
