INSTALLATION &
OPERATING INSTRUCTION
Main power connection
Before connecting the amplifier to the main power socket, be sure
that the voltage corresponds to the one indicated on the rear of
the unit (an allowance of 10% is acceptable). Before connecting
the power cable to the mains, always be sure that it is not damaged
and that there are no bare wires, always connect the power cable
to the amplifier before switching it on and only remove the cable
after switching it off.
Switching on and off
In an audio system, it's always better to switch power amplifiers
on last and off first. Remember to switch off the amplifier before
connecting it to or disconnecting it from other units and to always
switch 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.
Handling
Do not force knobs and connectors, as they could be damaged
if treated with excessive force.
Connections and prevention
of possible interference
Avoid installing your equipment near radios, televisions, etc., since
they could cause noisy disturbance. When connecting the other
units in your sound system, watch out for to so-called earth-loops,
which can cause hum: in the event of interference, try using the
EARTH switch on the amplifier's rear panel.
Connector cables
To connect the amplifier to the mixer, always be sure to use only
signal cables (screened cables made up of two wires plus a braid
screen), not power cables (speaker cables, normally made up of
two wires, usually with a greater cross-section): to connect the
amplifier to the loudspeaker enclosures, always use power cables,
not signal cables, as in the latter case in fact, the power from the
amplifiers would partially be dispersed because of the cable's
smaller cross-section. Take care of the connector cables. Always
hold them by the connectors, avoiding pulling the wire and avoid
knots and twists when coiling them: this gives the advantage of
increasing their life and reliability.
Air circulation for cooling
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 to the generated
temperature):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.

IMPORTANT SAFETY INSTRUCTION

Warning
When using electric products, basic precautions should always
be followed:
1.
Read all the SAFETY INSTRUCTIONS before using the product.
2.
This product must be earthed. If it has malfunction or breaks
down, grounding provides a path of least resistance for electric
current to reduce risk of electric shock. This product is equipped
with a cord having an equipment-grounding conductor and a
grounding plug.
The plug must be plugged into an appropriate outlet that is properly
installed and earthed in accordance with all local codes and
ordinance.
Danger
Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with a qualified electrician
or serviceman if you are in doubt as to whether the product is
properly grounded. Do not modify the plug provided with the
product - if it will not fit the outlet, have a proper outlet installed
by a qualified electrician.
3.
To reduce the risk of injury, close supervision is necessary when
the product is used near children.
4.
Do not use this product near water - for example, near a
bathtub, washbowl, kitchen sink, in wet basement or near a
swimming pool or the lake.
5.
This product may be capable of producing sound levels that
could cause permanent hearing loss. Do not operate for a long
period of time at high volume level or at a level that is uncomfortable.
If you experience any hearing loss or ringing in the ears, you should
consult an audiologist.
6.
This product should be located so that its location or position
does not interfere with its proper ventilation.
7.
This product should be located away from heat sources such
as radiators, heat registers or other products that produce heat.
8.
The product should be connected to a power supply only of
the type described on the operating instructions or as marked on
the product.
9.
This product may be equipped with a polarized line plug (one
blade wider than the other). This is a safety feature. If you are
unable to insert the plug into the outlet, contact an electrician to
replace your obsolete outlet. Do not defeat the safety purpose of
the plug.
10.
from the outlet when left unused for a long period of time. When
unplugging the power-supply cord, do not pull on the cord, but
grasp it by the plug.
11.
not spilled into the enclosure through openings
