Allen & Heath has launched the GR3 and GR4 installation mixers, designed to provide ‘simple yet comprehensive control of programme audio and announcements for multiple zones in bars, restaurants, stores and other leisure and retail environment’s.

Allen & HeathHighly configurable, the GR3 and GR4 are suited to applications requiring multiple input sources and specific priority settings. Both are 1U-high rackmount audio mixers, with features that include an easy access mic input on the front panel for announcements and paging, zonal auto-ducking for paging and emergencies, and optional wall plates for remote control. The control layout allows system integrators to manage which controls are accessible for everyday use.

The GR3 has two mic inputs and two stereo inputs, and the GR4 has four mic inputs and four stereo inputs. Additionally, the GR4 has a 3.5mm jack on the front to connect portable music sources, such as an iPod. Both units have two stereo zones, and an additional two mono zone outputs are available on the GR4.

There is individual mix and selectable control of all inputs to Zone 1 & 2, and multiple options for configuring mix outputs to Zones 3 & 4 via internal jumpers. Additionally, gain and two-band EQ is available on all mic inputs with a two-band EQ available on Zone 1 & 2 outputs. There is automatic ducking in primary and secondary mic mode, as well as emergency mic mode, and jukebox mode. Ducking parameters, such as attenuation, hold and release can be adjusted by entering ‘programming mode’ which also allows control over line input crossfade times and the priority line inputs hold and release times.

It is possible to connect up to two PL-14 wall plates or other analogue remote controllers, and paging and alarm contact inputs allow integration to third-party paging stations and fire alarm systems.

‘The GR3 and GR4 offering the same no-compromise build and sound quality that made GR popular with consultants and integrators around the globe but with carefully targeted features, a new style, redesigned interface and highly competitive price point,’ says Installation Sector Specialist, Ian Thomas.
