The Allen and Heath GR3 is a single rackmount or desktop audio mixer that provides comprehensive control of paging and background music in restaurants, bars, stores, and other retail/leisure environments.

  The mixer features two mic inputs on the rear panel via Phoenix connectors with an option to select Mic 1 from an XLR input on the front panel. Additionally, there are two pairs of stereo RCA connectors for audio playback devices. The two zone outputs are offered in stereo on Phoenix connectors, but may be changed to mono via internal jumpers. The optional PL-14 remote control provides a rotary volume control with four selectable source switches and connects via standard Cat5e cabling. The GR3 ships with a power cord, blanking bung covers, a set of rack ears, four countersunk Pozi screws, and 10 Phoenix connectors.
