A compact battery powered hand held remote controller for use with the Allen & Heath PL-4 and PL-11 wall plates which are equipped with an IR (infra-red) sensor. It has 14 user programmable buttons. These would typically be programmed by the installer as a combination of volume up/down, signal mute, source, preset select or MIDI messages for convenient control by the day-to-day operator. The PL-5 may also be used with the PL-12 wall plate for remote control of a GR2 audio zone mixer.
