The GR4 from Allen & Heath 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 four 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 four 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. An additional two mono zone outputs (3 & 4) are available with mix output being selectable from internal jumpers. The optional PL-14 remote control provides a rotary volume control with four selectable source switches and connects via standard Cat5e cabling.
