Instructions and installation
ATTENTION !!!
The PROCON series amplifiers generate high voltage on output.
To avoid the risk of electric shocks, DO NOT TOUCH any bare wires when the unit is
switched on.
This manual contains important information for correct safe use: read it carefully
before using your amplifier.

Connection to the mains supply
Before connecting the amplifier to the mains socket, always make certain that:
- the electric system and mains socket have an adequate grounding, compatible with the safety norms
(if you’re uncertain, consult specialized personnel);
- the mains voltage corresponds to that shown on the rear of the unit (an allowance of up to ±10% is
accepted);
- the power cord is not damaged and has 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 PROCON amplifier generates decidedly high power, so install it in locations which ensure 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 through the vents in the front panel and out through those on the
rear panel, so make certain that there’s sufficient space round the amplifier to allow adequate air
circulation.
If racks or flight-cases are used, make sure that airflow is unobstructed: don’t 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’s advisable to install the
amplifiers with at least one rack unit space between them.

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 fre-
quently. Always grip them by the connector, avoid pulling them forcefully and wind them without forming knots
or sharp bends: they’ll last longer this way and be more reliable, which is a definite advantage.
