Allen & Heath GR05 1u Rack Mount 5 In 4 Out Zone Mixer
GR05 is a 5-input, 4-output analogue zone mixer for sound installations requiring 2 mic and 3 stereo line to up to 4 mono or 2 stereo zones. Internal jumpers allow custom configuration protected for day-to-day operation by non-technical staff. Zone volume may be remotely controlled.
GR05_3Quarter_Main The GR05 has 2 microphone inputs and 3 stereo line inputs.
These can be assigned to 4 zone outputs configurable in mono or stereo pairs and controlled by front panel or remote level controls. GR05_Back_Main Ducking, EQ and muting can be configured.
Further inputs and outputs are possible using the expander system. GR05-ST version also available, with XLRs replaced by Euroblock (Phoenix) connectors.
