Important Safety Instructions – Read First

Read instructions: Retain these safety and operating instructions for future reference. Adhere to

all warnings printed here and on the console.

Power sources: Connect the console to a mains power only of the type described in this

Service Manual and marked on the rear panel. The power source must
provide a good ground connection.

Power cord: Use the power cord with sealed mains plug appropriate for your local mains

supply as provided with the console. If the provided plug does not fit into your
outlet consult the Allen & Heath technical support department for assistance.
Route the power cord so that it is not likely to be walked on, stretched or
pinched by items placed upon or against it.

Grounding: Do not defeat the grounding and polarisation means of the power cord plug.

Do not remove or tamper with the ground connection in the power cord.

Ventilation: Do not obstruct the ventilation slots or position the console where the air flow

required for ventilation is impeded. If the console is to be operated in a rack
unit or flightcase ensure that it is constructed to allow adequate ventilation.

Moisture: To reduce the risk of fire or electric shock do not expose the console to rain or

moisture or use it in damp or wet conditions. Do not place containers of
liquids on it which might spill into any openings.

Heat: Do not locate the console in a place subject to excessive heat or direct

sunlight as this could be a fire hazard. Locate the console away from any
equipment which produces heat such as power supplies, power amplifiers and
heaters.

Environment: Protect from excessive dirt, dust, heat and vibration when operating and

storing. Avoid tobacco ash, drinks spillage, and smoke, especially that
associated with smoke machines.

Handling: To prevent damage to the controls and cosmetics avoid placing heavy objects

on the control surface, scratching the surface with sharp objects, or rough
handling and vibration. Protect the controls from damage during transit. Use
adequate packing if you need to ship the unit.

Servicing: Switch off the equipment and unplug the power cord immediately if it is

exposed to moisture, spilled liquid, objects fallen into the openings, the power
cord or plug become damaged, during lightening storms, or if smoke, odour or
noise is noticed.

Installation: Install the console in accordance with the instructions printed in the User

Guide. Do not connect the output of power amplifiers directly to the console.
Use audio connectors and plugs only for their intended purpose.

Important Mains Plug Wiring Instructions

The console is supplied with a moulded mains plug fitted to the AC mains
power lead. Follow the instructions below if the mains plug has to be replaced.

The wire which is coloured Green/Yellow or Green must be connected to the
terminal in the plug which is marked with the letter E or with the Earth symbol.

This appliance must be earthed.

The wire which is coloured Blue or White must be connected to the terminal in
the plug which is marked with the letter N.

The wire which is coloured Brown or Black must be connected to the terminal
in the plug which is marked with the letter L.

Ensure that these colour codes are followed carefully in the event of the plug
being changed.
