INSTALLATION NOTES
At all times, the amplifier has to be operated under appropriate conditions. This includes that the
operation location provided sufficient ventilation and the device is not exposed to direct sunlight or
the direct radiation or reflection from any heat source. Installing the loudspeaker systems choose a
location that gets not affected by extreme and / or constant vibration or other mechanical oscillation.
also make sure that the speakers are installed at locations that are free from dust and / or moisture.
CAUTION
We strongly recommend that you leave the connection of the appliance to the qualified and
experienced service technician who is specialized in connecting electrical and electronically equipment.
Do not take the risk of Electro-shock or shock hazard. To reduce the risk of Electro-shock, all connections
have to be accomplished before it is permissible to connect the amplifier to the main supply, Before
carried out correctly and that no short-circuit connecting the appliance to the mains supply, once again
make certain that all connections are existing. The overall sound reinforcement installation has to be in
accordance to the laws, regulations, standards, and guidelines that are relevant and applicable in
the country where the equipment is going to be operated.
AC POWER SUPPLY
CAUTION
This equipment operates from a power source that does not apply more than 244 VAC(r.m.s) between
the supply conductors or between either supply conductor and ground.
DC POWER SUPPLY
CAUTION
A 24V DC power source (i.e. a battery) has to be connected to the terminals (13) that are covered by a
protective lid. To reduce the risk of dropping voltage to a minimum and to eliminate the danger of damaging
the battery cables by thermal overload, these cables have to be at least 2.5mm in diameter, each
Switching the amplifier on or off is performed through the power switch (6).
CONNECTING THE OUTPUT TERMINALS
CAUTION
TERMINALS marked with the symbol are HAZARDOUS LIVE and the external wiring connected
to these TERMINALS requires installation by an INSTRUCTED PERSON or the use of ready-made lead
or cords to avoid the risk of electrical shock,
terminals of the amplifier when it is in operation. Under figures, show the possible connections of the
" OUTPUT" speaker terminals accessible by removing the protective cover. Bear in mind the following
rules:
Constant impedance lines
The total impedance of the speakers connected must correspond to that selected on the amplifier's
output terminals.
The sum of the power capacities of the speakers must be no lower than the amplifier's power capacity.
The length of the connecting cables must be as possible; in any case, the longer the distance to be
covered and the greater must be the cross-section of the cables.
Constant voltage lines
Each speaker must be equipped with a line transformer with an input voltage equal to that of the line (25,
70, 100V).
The sum of the power capacities of the speakers must not exceed the output power capacity of the
amplifier (i.e. total wattage of speakers installed in zones 1 through 5).
never touch the bare conductors leading to the output
