Audio connections

Remember to always connect and disconnect other units with the amplifier switched off.
Always use good quality cables of the appropriate type, opportunely described in the connection cables
chapter of this manual.
Take care of your connector cables, a very frequent cause of small/big problems. Check their condition
frequently.Always grip them by the connector, avoid pulling them forcefully and wind them without
forming knots or sharp bends: they will last longer this way and be more reliable, which is a definite
advantage.
Preventing or identifying interference
First of all, check that the amplifier is installed in a place free from industrial of RF (radio frequency)
Interference.
Avoid installing your equipment very near radio or TV sets, mobile phones, etc., as these can cause
noisy interference.
When connecting the other components of your sound system, watch out for the so-called round loops,
which could cause hum and jeopardize the amplifier excellent signal-to-noise and low distortion
characteristics.
The best way (even if not always feasible) to avoid ground loops is to connect the electric ground of all
the equipment to a single central point (the so-called star system). In this case, the central point in
sound systems is the mixer.
To help identify the cause of any interference, connect the various sections of the mixer to the rest of
the equipment in the following order,listening to the resultant sound as your proceed with connection:
Outputs: amplifiers + loudspeaker enclosures (master outputs);
Amplifiers + monitors (AUX outputs);
Effects (AUX outputs or EFF send/return);
Inputs: instruments with line signals (keyboards, samples, recorders, etc.);
Microphones ( lastly and one by one).
Electric products must not be put into household waste. Please bring them to a recycling centre. Ask your local
authorities or your dealer about the way to proceed.
