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.
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.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Avoid flames and do not put close to flammable liquids or gases.
Avoid ground loops! Always be sure to connect the power amps and the mixing console to the
same electrical circuit to ensure the same phase!
Avoid installing your equipment very near radio or TV sets, mobile phones, etc., as these can cause
RF (radio frequency) interference.
Before changing your grounds around, always turn your amplifiers down.
Before connecting or disconnecting the power cord, make certain the ON / OFF switch is in the OFF
position.
Before switching on or off make certain the sound system’s amplifiers are off or turned down: this will
avoid signal peaks, which are annoying and sometimes dangerous (particularly for speaker
enclosures).
Do not connect (parallel or series) an amplifier output with any other amplifier output.
