It has a flexible architecture which allows easy custom configuration by the installer to exactly suit the requirements of the installation. Once installed it presents a simple control interface for day-to-day operation by non-technical staff.

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.

The GR05 ships with mains leads, user guide, spare knobs & faders, A&H stickers.
