    Introduction This publication provides technical information on servicing the Allen & Heath GR2 Audio Zone Mixer. Included are internal layout drawings, block diagrams and circuit schematics with board layouts. Whilst we believe this information to be reliable we do not assume responsibility for inaccuracies. We also reserve the right to make changes in the interest of further product development.
  • Page 3 Technology: The GR2 uses SMT (surface mount) PCB technology. In certain cases it may be better to replace a faulty assembly rather than try to fix it without the appropriate tools and training. The power supply is a built-in universal mains input, switched mode circuit which should be serviced by suitably qualified personnel only.
