Description

GR2

The GR2 is a 9-input, 4-output analogue zone mixer for sound installations requiring 6 mic/3 stereo line or 4 mic/4 stereo line to 1 stereo/1 mono zone and aux output. All settings are custom configurable from the front panel and are protected by a cover plate for day-to-day operation. Zone source selection, volume and more may be remotely controlled.

GR2 FEATURES

  • 6 MIC/LINE INPUTS WITH EQ
    • Balanced inputs are provided on terminal blocks for convenient pre-wiring, with Mic 1 duplicated on XLR for quick plug-and-play. Each input has selectable +15V phantom power, protected mic/line pads and gain trimmers. There is a mic priority function for chairman or MC override, and a mic mute. The mic also has dedicated EQ with swept HPF, swept MF and shelving HF. An expander input allows more mics to be added to the mix.
  • 3 (OR 4) STEREO MUSIC INPUTS
    • Music channels are provided on RCA inputs with protected -10/+4 level settings. Mic/line 5/6 can be configured as a stereo input providing a 4 mic, 4 stereo line system. Inputs may be configured one at a time, or all together.
  • PAGING & MUSIC PRIORITY OVERRIDE
    • GR2 offers a dedicated paging channel with tailored EQ for speech intelligibility. The source can be configured from Mic 1 and/or an external input or alarm message and the zone program is ducked when a page signal is detected. Music 1 may be configured as a priority input for jukebox and pre-recorded message override.
  • MONO & STEREO ZONE OUTPUTS
    • Outputs are available on both RCA and terminal blocks for pre-wiring or plug-and-play operation. Stereo Zone 1 may be configured for music only or music + mics, and mono Zone 2 can be configured for mics, music or music + mics. VCAs are provided for ducking, alarm override and remote level control. Zone 1 features a 2-band EQ and a mono switch.
  • MONO AUX OUTPUT
    • A versatile output for additional zone, mic expander, paging distribution, sub bass and more is provided on RCA and terminal block connectors. It is configurable as page out, mic mix, follow Zone 1 or Zone 2, and has a switchable 100Hz LPF for sub-bass feed.
  • CONFIGURATION PROTECTION
    • All settings are configured from the front panel. Preset dip switches are letter coded, and trimmers recessed for screwdriver access. A cover plate protects the settings and provides space for fitting a custom label. Any of the rotary knobs may be removed and hole plugs fitted as required.
