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.
•
To prevent humming, please try different combinations of ground-lift or connect all chassis to the
system ground, either by a power cable or frontcover rack screws.
•
Before changing the ground, always turn off your amplifier.
•
Please read this manual carefully and keep it for future reference. Remember that the amplifier has a
better value on the market, if you save the carton and all packing materials.
•
Prevent distortion! Make sure that all components connected to the PA240 have sufficient power
ratings. Otherwise distortion will be generated because the components are operated at their limits.
•
Make sure you don’t use the wrong kind of cables or defective cables.
•
Make sure that signals into the mixer are balanced, otherwise hum could be created.
•
If device is dropped or struck, disconnect mains power supply immediately. Have a qualified
