    Description

    GR4 is a 1U rack-mounting or desktop audio mixer, providing simple yet comprehensive control of background music and paging in bars, restaurants, stores and other leisure / retail environments. Standout features include optional remote wallplates, a mic input on the front panel, plus a 3.5mm jack on the front for portable music sources.

    Connectivity:

    • MIC INPUTS
      Four mic inputs on rear mount Phoenix connectors with MIC1 selectable to an optional front mounted XLR.
    • LINE INPUTS
      Four stereo inputs on rear mount phono connectors. An additional front mounted 3.5mm jack socket overrides input 4 phono source.
    • ZONE OUTPUTS
      Two stereo (mono selectable via internal jumper) zones on rear mount Phoenix connectors. An additional two mono zone outputs are available with mix output being selectable from internal jumpers.
    • CONTROL
      Paging and Alarm contact inputs on rear mounted Phoenix connectors allow integration with 3rd party paging stations and fire alarm systems.
    • REMOTE
      Remote control can be achieved via PL-14 Remote connected to the rear mounted RJ45 or custom/3rd party analogue remotes connected to the rear mounted Phoenix connectors.

    Features:

    • MIXING
      Individual mix and selectable control of all inputs to Z1 & Z2. Multiple options for configuring mix outputs to Z3 & Z4 (via internal jumpers).
    • DYNAMICS
      Gain and 2 band EQ available on all mic inputs with an additional 2 band EQ available on Z1 & Z2 outputs.
    • PRIMARY MIC MODE
      When audio sensed on MIC1 channel and/or PAGE contact closure is sensed then music is faded to pre-set level and MICs2-4 muted for the duration of the announcement. MIC1 zone select LEDs flash slowly when in priority mic mode.
    • GAIN / VOLUME ROTARY CONTROLS CAN BE REMOVED AND CAPPED (CAPS SUPPLIED) TO PREVENT UNAUTHORISED USE.
