ALLEN AND HEATH MIXERS - GR Series - Installation

A range of zone mixers designed for installation projects, to give control over background music and paging. The GR series include analogue inputs, from four input channels to nine input channels, zone outputs ranging from two zone to four zone, and flexible routing via installer-set parameters to suit a wide variety of installation setups. Front panel controls allow day to day functionality, while further controls can be accessed behind access panels or on the rear panel. The units may be used free-standing, or mounted in 1U of rack space.

GR2

The GR2 is a compact, nine-input, four-output installation mixer, with a simple front panel and a wide range of installer-configurable options. Each input and output has a 2-colour level control LED status indicator on the front panel. For complete 'fit and forget' installations, the level knobs may be removed and blanking plugs fitted to avoid tampering.

Configurable as six microphone channels and three stereo inputs, or four microphone channels with four stereo inputs. One balanced microphone/line input channel has XLR connection, Phoenix connectors for channels two to six, and gain controls on the front panel and switches to set 15V phantom power, mic/line level, swept EQ, high-pass filter, ducking, and routing. The GR2 has two RCA phone output channels, one stereo and one mono, duplicated on balanced Phoenix. Each output has VCAs for page ducking, alarm override and remote level control, and zone 1 output has a two-band EQ with shelving. RJ45 connector for use with CAT5 cable enables remote use of zone 1 and/or zone 2 by connecting PL-12 remote control.

Inputs: -60 to -20dBu, 2000 ohms, microphone; -30 to +20dBu, 10000 ohms, with pad selected for line level; +15V phantom power; -10dBV or +4dBu, dual RCA phono 50k ohm, stereo music channels. Response: 20Hz to 20kHz. Noise: better than -85dB, mix noise (one selection, zone level max.), better than -91dBu, residual output noise (zone level min.) Output: 0dBu, better than 75ohms load, balanced. Dimensions: 483 x 235 x 44mm (w x d x h). Weight: 3.6kg.

Included accessories: User guide, bolt on rack ears for 19inch casing, AC power lead.

GR3

Much like the GR2, the GR3 is a compact installation mixer designed to suit a wide range of installation requirements. The GR3 is a four in, 2 zone output desktop or 1U rack fitting mixer with configurable routing options. Mic 1 and Mic 2 inputs utilise 3-pole 'Euroblock' (Pheonix style) connectors, and have adjustable rotary level controllers with Off to +6dB control on the front panel. An XLR input on the front panel can be used as an alternative for the rear Mic 1 Euroblock input. The two unbalanced phono stereo line inputs also have front panel level control from off to +6dB.

Both zone 1 and zone 2 output channels are preceded by separate LF and HF controllers. The shelving LF gives +/-15dB with a cut off frequency at 80Hz, while the shelving HF gives +/-15dB with a cut off frequency set at 8kHz. Each zone also has separate Mic/Music level controls, Off to +6dB, with Mic/Music select switches. Three-segment LED L+R output meters with illumination at -18, +3 and +17dB offer insight to the zone output channels. PL-14 wall-mount remote can connected with CAT5e cable to give remote level control.

Inputs: 0dBu to -50dBu, 2000 ohms, mic input; 0dBu or -10dBu, stereo line. Response: 20Hz-20kHz, +/-1dB. Noise: microphone input -77dBu (150 ohm source), 22Hz-22kHz; ST input -90dBu, 22Hz-22kHz. Output: Main zone level 0dBu maximum, balanced. Power consumption: 15W (no remote attached), 20W maximum. Dimensions: 438 x 242 x 48mm (w x d x h). Weight: 3.4kg.

Included accessories: User guide, bolt on rack ears for 19inch casing, blanking bungs, 2-pole Euroblock header plugs, 3-pole Euroblock header plugs, 4-pole Euroblock header plugs, AC power lead.

GR4

The GR4 line mixer is essentially two GR3s in one compact desktop or rack mountable box but with eight-inputs and four zone outputs. Mic 1,2,3,4 inputs have 3-pole Phoenix connections, adjustable rotary level controllers with Off to +6dB control on the front panel. An XLR input on the front panel can be selected as an alternative for the rear Mic 1 Euroblock input via a switch. The four unbalanced phono stereo line inputs also have front panel level control from off to +6dB.

Jukebox mode can be selected, via dip switches C and D to fade down the stereo line music feeds when music is sensed on ST3. This returns when a pre-set period of silence is detected on ST3. Mic volume not affected. A 3.5mm jack socket on the front panel overrides an input connected to ST4.

Zone 1 and 2 output channels come after separate LF and HF controllers, zone 3 and 4 have no EQ. The shelving LF gives +/-15dB with a cut off frequency at 80Hz, while the shelving HF gives +/-15dB with a cut off frequency set at 8kHz. Zone 1 and 2 have separate Mic/Music level controls, Off to +6dB, with Mic/Music select switches. Three-segment LED output meters with illumination at -18, +3 and +17dB offer insight to the zone output channels. PL-14 wall-mount remote can connected with CAT5e cable to give remote level control.

Inputs: 0dBu to -50dBu, 2000 ohms, microphone input; 0dBu to -10dBu, ST input sensitivity. Response: 20Hz-20kHz, +/-1dB. Distortion: 0.005%. Noise: microphone input -77dBu (150 ohm source), 22Hz-22kHz; ST input -90dBu, 22Hz-22kHz.Output: 0dBu nominal (-10dBu with optional jumper), +21dBu maximum, balanced. Power consumption: 15W, 20W maximum. Dimensions: 438 x 242 x 48 (w x d x h) mm. Weight: 3.4kg.

Included accessories: User guide, bolt on rack ears for 19inch casing, blanking bungs, 2-pole Euroblock header plugs, 3-pole Euroblock header plugs, 4-pole Euroblock header plugs, AC power lead.

GR05

The GR05 is a compact, five-input, four-output, installation mixer, with a simple front panel and a wide range of installer-configurable options. Each input and output has a level control and three-colour LED status indicator on the front panel. For complete 'fit and forget' installations, the level knobs may be removed and blanking plugs fitted so just the status lights and a mute button remain. All inputs can be routed to any combination of outputs direct or via the VCA control.

The direct path is not affected by output level controls and ducking. Selection is done by internal jumper links, VCA control is used for output ducking. Ducking depth and release time can be assigned. Muting is possible. There is an opto-isolated input for external trigger and four additional direct / VCA bus inputs are provided on the expander / remote connector. Alarm interface is possible. There is a status indicator on the front panel.

Two balanced microphone/line input channels have XLR connectors and gain controls on the rear panel and internal presets and jumpers to set 15V phantom power, mic/line level, swept EQ, high-pass filter, ducking, and routing. Three stereo RCA (phono) line-level inputs have internal jumpers for level matching, routing and ducking presets. Each output has an XLR connector, separate internal ducking control, two-band EQ and level presets. A female D-sub 25-pin 'Expander/remote' connector allows multiple units to be linked for larger systems, a remote VCA and ducking control, and external DC power supply for maintained systems.

Inputs: -22 to -58dBu, 2000 ohms, microphone; -28 to +8dBu, 10000 ohms, with pad selected for line level; -10dBV or +4dBu, 10000ohms, stereo line. Response: 20Hz-50kHz, +0/-1dB. Distortion: 0.005%. Noise: -128dB RMS EIN, 150 ohm source, 22Hz-22kHz, microphone; -91dBu, preamp at 0dB gain, line; better than -86dB mix noise (all channels routed). Output: +20dBu maximum, 22k ohms load, balanced. Power consumption: 18VA maximum. Dimensions: 483 x 260 x 44(w x d x h) mm. Weight: 4kg.

Included accessories: User guide, spare knobs and faders, hole plugs, AC power lead.

PL-12

PL-12 remote controller can be connected by CAT5 cable to the RJ45 connection of the GR2 to provide the non-technical operator with local and remote level and source selection for both zones. Up to two controllers may be connected: one for each zone, or a single unit to control both zones together. The second controller daisy chains with the first for single run cabling.

The PL-12 can be mounted into a single unit wall box using the standard face plate provided, or furniture mounted using a cutting template. Space is provided on the panel for custom labelling.

PL-14

PL-14 remote controller can be connected by CAT5 cable to the RJ45 connection of the GR3 or GR4. Local and remote level and source selection for both zones. Up to two controllers may be connected: one for each zone, or a single unit to control both zones together.

The PL-14 can be mounted into a single unit wall box using the standard face plate provided, or furniture mounted using a cutting template. Space is provided on the panel for custom labelling.
