WARNING 

 
 
 
 
 

FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY  

BEFORE YOUR INITIAL START-UP! 

 

SAFETY INSTRUCTIONS 

Every person involved with the installation, operation and maintenance of this system have to: 

-

 

be qualified 

-

 

follow  the instructions of this manual

 

 

 

 
 

 

Before you initial start-up, please make sure that there is no damage caused by transportation. Should 
there be any, consult your dealer and do not use the system. 

 

To maintain perfect condition and to ensure a safe operation, it is absolutely necessary for the user to 
follow the safety instructions and warning notes written in this manual. 

 

Please consider that damages caused by manual modifications to the system are not subject to 
warranty. 

 

This system contains no user-serviceable parts. Refer servicing to qualified technicians only. 

 

IMPORTANT:

 

The manufacturer will not accept liability for any resulting damages caused by the non-
observance of this manual or any unauthorized modification to the system. 

 

 

Never let the power-cord come into contact with other cables! Handle the power-cord and all 
connections with the mains with particular caution! 

 

Never remove warning or informative labels from the unit. 

 

Never use anything to cover the ground contact. 

 

Do not insert objects into air vents. 

 

Do not connect this system to a dimmer pack. 

 

Do not switch the system on and off in short intervals, as this would reduce the system’s life. 

 

Do not open the device and do not modify the device. 

 

Do not open this device. Risk: hazardous radiation exposure. 

 

Only use system indoor, avoid contact with water or other liquids. 

 

Avoid flames and do not put close to flammable liquids or gases. 

 

Always disconnect power from the mains, when system is not used. Only handle the power-cord 
by the plug. Never pull out the plug by tugging the power-cord. 

 

Make sure you don’t use the wrong kind of cables or defective cables. 

 

Make sure that the signals into the mixer are balanced, otherwise hum could be created. 

 

Make sure you use DI boxes to balance unbalanced signals; all incoming signals should be clear. 

 

Make sure that the available voltage is not higher than stated on the rear panel. 

 

Make sure that the power-cord is never crimped or damaged. Check the system and the power-
cord from time to time. 

 

Make sure that the amplifier is turned down, before turning the power on or off. So you can avoid 
supersonic frequencies, which could damage your speakers. 

 

Don't put your equipment next to TV, radio, etc., because of interference or distortion. 

 

If you connect other parts of the system, be careful of ground loops. 

 

The best way to avoid ground loops is connecting the electrical system ground to one central 
point ("star" system). In this case the mixer can act as a central point. 

 

Before changing the ground, always turn off your amplifier. 

CAUTION! 

 

Keep this system away from rain and moisture! 

 

CAUTION! Be careful with your operations. 

With a dangerous voltage you can suffer 

a dangerous electric shock when touching the wires!
