Rear Panel - Connections

1. Power ON/OFF switch

This switch is rear panel mounted to prevent accidental
or illegal user operation. Press to switch on or off.

To avoid power up thumps, make sure power

amplifiers are turned on last and turned off first.

2. Mains input IEC connector

Check that your local mains supply matches
that marked on the rear of the unit. Check that
the mains IEC plug is correctly seated.

3. Mains fuse

Replace only with the type and value marked on
the rear panel. Turn the unit off and unplug the
power cord before removing the fuse.

4. Mic 1 XLR input

The mic 1 input is duplicated on both XLR and Phoenix
screw terminal plug for installer convenience. This is
convenient for pre-wiring custom cables or using a
standard XLR mic cable. Only one connection should
be used. The input is balanced pin2=+ and can be

configured to provide phantom power.

5. Mic 1-6 Phoenix plug inputs

The inputs are balanced, each with +, - and ground
connections. Plug mic 1 into either the Phoenix or the
XLR, not both. Phantom power can be configured to a

combination of mics 1, 2, 3+4, 5+6. Line level sources
may be used by setting the front panel configuration pad
switches. Sensitivity can be adjusted to accept signals
within the range -60dBu to +20dBu. Mics 5/6 may be
configured as another stereo mic or line music source

with balanced input suitable for long cable connection.

6. External Page input

Balanced with +, - and ground connections to input a
0dBu external line level signal to the page mix. This
mixes with mic 1 if it has been configured as a paging
mic. Use with an external source such as paging or pre-

recorded evacuation / safety message.

7. Mic expander input

Balanced with +, - and ground connections to feed a
0dBu external line level signal to the mic mix. Plug
another GR2 in to expand the number of mic inputs.

This input is muted when mic priority is active.

8. RCA phono music inputs

Unbalanced line level stereo inputs for connection to
music and other stereo sources. Sensitivity may be
configured for +4dBu or -10dBV operation. To prevent

unnecessary signal crosstalk, plug the RCA shorting
plugs provided into any inputs which are not being used.

9. Zone 1 L and R output

Stereo zone 1 output is available on balanced Phoenix
and unbalanced RCA phono plugs. Both may be used

at the same time to split the signal to two different
destinations. Nominal level is 0dBu with +20dBu max..

10. Zone 2 output

Mono zone 2 output is available on balanced Phoenix
and unbalanced RCA phono plug. Both may be used at

the same time to split the signal to two different
destinations. Nominal level is 0dBu with +20dBu max.

11. Aux output

Mono aux output is available on balanced Phoenix and
unbalanced RCA phono plugs. Both may be used at the

same time to split the signal to two different destinations.
Nominal level is 0dBu with +20dBu max.

12. Zone remote

Allows daisy chain connection to Allen & Heath PL-12
wall plates or custom wired or third party remote panels

to control zone 1 and 2 levels and source selections.
Standard RJ45 plugs and CAT5 cable may be used.

13. Utility remote

Allows connection to custom wired or third party
controllers for remote page enable, mic mute and

priority, and alarm trigger. Standard RJ45 connectors
and CAT5 cable may be used.
