There are no user serviceable parts inside.  Refer any service work to 
competent technical personnel only. 

Power sources:

 

 

Connect the console to mains power only of the type described in this User 
Guide 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 your service agent.  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.  To avoid injury to yourself or 
damage to the equipment take care when lifting, moving or carrying 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. Refer servicing to qualified technical personnel only. 

Installation:

 

   

Install the console in accordance with the instructions printed in this 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
