Introduction

for the iDR audio mix processor system. It is part of the Allen & Heath PL
Series of wall plates and remote controllers. It is a wall plate or furniture
mounted module comprising plastic control panel and attached circuit
assembly. It can be mounted in a single unit wall box using a standard face
plate (UK, EU or US version supplied). A suitable template with cutting details
is provided for custom application. The PL-4 interfaces with the Allen & Heath
PL-Anet serial port. Multiple PL-4 units can be daisy chained together along
with other PL-Anet devices using CAT5 cable. For information on the full range
of PL products available visit http://www.idrseries.com. The wall plate control
and indicator functions are programmed using the iDR System Manager
software. Space is provided on the control panel for custom labelling. The PL-
4 is ideal as a wall mounted room remote controller in installed audio systems.
The installer can program the unit so that the non-technical operator has local
control of volume, mute, source select, and preset changes which reconfigure
the room for different functions, as well as the convenience of the PL-5 infra-
red remote controller.
2 switches can be assigned for level up or down control (input, output,
crosspoint or group), mute toggle, audio monitor select, or preset recall. 4
LED indicators can be assigned as audio meters (choice of 8x points in the
signal path), mute status, or as preset related static display. They can display
four states: off, green, yellow or red. Rotary control can be assigned as a
continuous level control (input, output, crosspoint or group). An 8 LED meter
bar displays the control position. Infra-red controller allows wireless local

Number and addressing of devices

ROOM 3
PL devices that can be connected depends on their type and the cable
lengths. Up to 12x PL-4 devices (more if using half speed scan) may be
connected in an iDR system, with or without the PL-9 hub. Fewer devices may
be connected if long distances or other PL types are also involved. To check
