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.
