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. 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.
