It is endowed with protection systems preventing damages caused
by short circuits, overheating and overloads and making it safe and
reliable.
Before making any connection, check that the unit is unplugged
from the electrical outlet.
All connections must be made with the appliance turned o󰀨.
It can manage both 8 Ohm and 70V / 100V constant voltage
connections.
This amplier has been designed for “P.A. system“ applications.
It is used for example in o󰀩ces, schools, churches, shops, shopping
centers, restaurants, convention centers, auditoriums, etc.
It comes with 2 microphone inputs, 1 AUX input and 1 AUX
output.

This type of connection does not allow to limit individually the power of
each single speaker, but it gives the possibility to obtain higher
performances.
The main rule to be respected is that the total impedance of the
speakers must be compatible with the impedances managed from the
amplier to which the speakers will be connected (generally 4, 8, 16Ω).
If you use more than one speaker, the value of impedance will be
added up or divided depending on the type of connection (series or par
allel).
If you connect only one speaker you have to consider the impedance of
the speaker itself.
Here are two examples of connection:
Speaker impedance matching
Series wiring
The impedances add up. In this example
the 4 x 4Ω speakers can be connected to
one amplier suitable for 16Ω connections.
Parallel wiring
The impedances are divided. In this example
the 4 x 16Ω speakers can be connected to
one amplier suit-able for 4Ω connections.

Until you use few speakers it is easy to reach 4, 8, 16
Ω required by common ampliers,
but when using more speakers
it is necessary to choose a type of mixed
series / parallel connection allowing us to
obtain the desired impedance.
Series / parallel mixed wiring
In this example the impedance of the 4 and 8Ω
speakers is added (being connected in series). Then
the 4 groups of speakers, connected in
parallel, halve their impedance to reach a total
impedance of 4Ω.
Here is an example:
4 speakers x
4 Ω = 16 Ω

EXAMPLE: You connect to the system 5 speakers for a
total of 115W. The
amplier handles up to 360W: so it is possible to connect
other speakers,
up to reach the amplier’s maximum
power.
Constant voltage
speakers connection
It is the type of monophonic system realized in shops, conference rooms,
churches and in any environment where a uniform sound di󰀨usion in neces
sary, with maximum ease of installation and use. Only 2 wires are used, starti
ng from the amplier and getting up to the last speaker. On the amplier you
have to connect a wire to the “com”(common) terminal and the other wire to t
he terminal indicating 100V.
The two wires will go all around the installation, and they will be connected to
the speakers or rather the transformers included in the speakers. The
speakers of this type, have generally a selector to set the emission power,
from the minimum to the maximum value supported by the transformer.
As a matter of fact, it is possible to connect to the same 2 main wires,
a number of speakers, even di󰀨erent from each other or with di󰀨erent power.
The amplier signal will reach the transformer present in each speaker and
the transformer will provide the desired power.
When you operate on the amplier’s volume, the volume of all speakers will
be increased or reduced accordingly.Important: the sum of the maximum pow
er of the speakers must be equal to or less than the amplier’s maximum pow
er .
