Every installation is different and the range of venues where sound is required is enormous, so flexibility is the key: the GR2 offers the installer a host of front panel preset switches and trimmers to meet specific system requirement. After installation, the settings are protected by a cover plate, unused controls may be blanked off and the operator is presented with a simple, uncluttered interface for day-to-day operation.

Designed for the latest installation methods, the GR2 features a combination of XLR/RCA and screw terminal connectors for pre-wired or plug-and-play installation and extensive remote control capability using standard Cat5 cable.

Lastly, in true Allen & Heath tradition, our experience with producing high-end mixing consoles has allowed us to design high quality audio circuitry, making a the GR2 a great sounding mixer.

The GR2 ships with mains leads, user guide, spare knobs & faders, A&H stickers.
