GR2 User Guide 5
Welcome to the GR2
The GR2 is a compact 9 in 4 out 1U rack mount analogue zone mixer with 6 mic
and 3 stereo line inputs, two zone outputs (1 stereo, 1 mono), and an assignable
mono aux output.
It is configured by the installer for a variety of applications by setting front panel
DIP switches and presets. These are accessible by removing a cover plate
which protects the settings during day-to-day operation, and can be used to
mount a custom ident label. Simple controls such as mute, source select and
level are available to the operator, or can be plugged to lock their function. A
combination of XLR, phono and Phoenix screw terminal connections is provided
to conveniently suit both the freestanding and installed applications. Additional
connections are provided to input external paging and alarm audio signals, and
to expand the number of mics beyond 6 by linking GR2 units. Exceptional
capability is provided with functions such as paging, mic priority, music
override, alarm input, and independent mic and zone EQ.
Each input channel and zone output is provided with its own level control and
signal meter. Level and/or source selection for each zone can be configured for
local front panel or remote control using industry standard 10V control. The
installer can make simple potentiometer/rotary switch wall plates, interface with
third party systems such as AMX, or use the Allen & Heath PL12 wall plates with
or without the optional PL-5 infra-red controller. A utility socket allows remote
control of page selection, mic muting and priority, and alarm trigger.
