Connection to the mains supply
Before connecting the amplifier to the mains socket, always make sure that:
●The electric system and mains socket have an adequate grounding, compatible with the safety
norms (if you are uncertain, consult specialized personal ).
●The mains voltage corresponds to that shown on the rear of the unit (an allowance of up + / - 10% is
accepted).
●The power cord is not damaged and that no bare wires.
●The ON / OFF switch is in the OFF position.
●Make sure the amplifier is also off before disconnecting the power cord from the mains socket.
Switching on and off
In your sound reinforcement system, always switch on the amplifier after all the other equipment and
always switch it off before anything else, if possible with the gain controls set at minimum: this will
avoid annoying and sometimes dangerous signal peaks.
Installation and use
Your DIGITAL POWER amplifier generates decidedly high power, so install it in locations with correct
air circulation.
Avoid long exposure to direct sunlight, sources of strong heat, powerful vibrations, very dusty or
particularly damp surroundings or (even worse) rain: this will avoid possible faulty operation,
deterioration or even electric shocks and fires.
The air for cooling the unit is forced in though the vents in the front panel and out though those on the
rear panel, so make sure that there is sufficient space around the amplifier to allow adequate air
circulation.
If racks or flight-cases are used, make sure that airflow is unobstructed: do not install the amplifiers in
racks or flight-cases with closed backs.
Since part of the heat is dissipated via the metal bottom of the amplifier, it is advisable to install the
amplifiers with at least one rack unit space between them.
