DESCRIPTION

−

Allen & Heath delivers reliable, no-nonsense signal management with the GR4 — a compact 1U rackmount zone mixer purpose-built for commercial installations. Featuring 8 inputs and 4 independent zone outputs, the GR4 provides integrators with a streamlined solution for multi-zone audio distribution in restaurants, retail spaces, hospitality venues, and corporate environments.

The mixer accepts four stereo input sources, including a dedicated RIAA phono input for turntable connectivity, making it versatile enough to handle a wide range of programme material. Each of the four output zones features independent level control, allowing precise tailoring of audio levels across different areas of a venue from a single rack unit.

  • 8 inputs (4 stereo channels) with flexible source selection per zone
  • 4 independent zone outputs with individual level control
  • Dedicated RIAA phono input for direct turntable connection
  • Logic control inputs for external ducking and priority paging integration
  • Headphone output for local monitoring and system commissioning
  • 1U 19" rackmount format for clean, space-efficient installation

Built to Allen & Heath's exacting standards, the GR4 offers the audio quality and long-term reliability that professional installers demand. Its straightforward architecture reduces commissioning time while delivering flexible, high-quality zone mixing in a robust, rack-friendly package.
