High quality for performance amplifier
Installation & operating instruction
1
Before connecting the amplifier to the mains power socket, make certain that the voltage
corresponds with that indicated on the rear of the unit
(An allowance of ±10% is acceptable).
Before connecting the power cable to the mains, always make certain that it is not damaged
Always connect the power cable to the amplifier before switching it on and only remove the
cable after switching it off.
In an audio system, it's always better to switch power amplifiers on last and off first.
2
Remember to switch off the amplifier before connecting it to or disconnecting it from other units
and to switch always on first the mixer and then the amplifier : in this manner, peaks which are
annoying and sometimes dangerous particularly for the loudspeakers enclosures are avoided.
It is normal for the LEDs to light up for a few moments when switching on.
3
When connecting the other units in your sound system, watch out for to so-called earth-loops,which can cause
hum: in he event of interference, try using the EARTH switch on the amplifier's rear panel.
Avoid installing your equipment near radios, televisions, etc., since they could cause noisy disturbance.
4
Do not force knobs and connectors, as they could be damaged if treated with excessive force.
Do not expose the amplifier to inviroment moisture Do not expose the amplifier to corrosive
5
chemicals such as soft drinks, lye, salt water, etc.
6
Amplifier's correct cooling is ensured by an internal fan, the speed of which is controlled by a special
sensor (the speed is proportional to output power and therefore the temperature generated),
remember never to block the air vents located on the unit's sides in any way: the air necessary for
cooling passes through these. If the amplifier is kept in a flight-case during use, make certain that
it has sufficient openings at both the amplifier's air vents. Avoid locating it very small spaces which
don't allow correct air circulation.
