Remote Control – Zone Level and Source Selection
Voltage control Level and source selection are voltage controlled
using an internal or external +10V DC reference voltage. This
means they can be controlled in many different ways including
custom wired potentiometers, switches and interface circuits, third
party controllers such as AMX or Crestron, or the Allen & Heath PL-
12 intelligent wall plate with PL-5 infra-red controller option.
LEVEL 0V=off +10V=maximum (0dB)
SOURCE 0V=off, +2V=1, +4V=2, +6V=3, +8V=4
Configure remote control Set the front panel DIP switches M,
N, O, P to configure which zones and functions to control.
CAT5 wiring The two zones are wired from one RJ45 socket,
convenient for daisy chaining two zone wall plates using a single
CAT5 cable run. Use standard CAT5 UTP or STP cable terminated
with an RJ45 plug at the GR2 and wired to the circuit at the wall
plate. Wire the circuit according to the RJ45 pin numbers shown
here. If you are using pre-installed cables, note that there are two
CAT5 connection standards, 568A and 568B. The cable colour code
differences are shown in the diagram. Check the pinout first.
Level control Use a linear law rotary potentiometer or a switched
resistor ladder to control the zone level. Use a potentiometer or
ladder value between 2k and 10k ohms. We recommend 4k7 ohms.
Source selection Use a resistor ladder wired to a rotary or other
type of switch. We recommend 5x 1k ohm resistors wired as shown
in the diagrams here. Wire the switch to the resistors according to
the combination of sources to be used, for example1234, 123, 234,
23. Switching to 0V provides an off position if required. Note that
you may wish to exclude music 1 from the source selection if it has
been configured as the priority source such as a jukebox.
Check the wiring before connecting power Ensure
the CAT5 cable is correctly wired. Check the continuity of all wiring.
Ensure there are no shorts or exposed wire ends.
10V power Do not draw more than 100mA from each
+10V pin. The internal 10V supply is protected against a short
circuit using a resettable fuse. If it trips, turn off the GR2, wait a few
seconds and turn it back on again.
