STEADY VOLTAGE SYSTEMS
This connection system requires that each speaker be equipped with
a dedicated line transformer. The amplifier must have steady voltage
outputs of 100V or 70V. Should it be necessary, the loudspeakers
connected in parallel to the output of the amplifier allow you to extend
the installation from any of the previously installed speakers, and also
to remove the loudspeakers when no longer needed. When making
the connections, you have to observe the "phase" of speaker
connection to its own transformer and also that of the parallel
connection of the speakers. The input voltage of the speaker must
match the output voltage of the amplifier; the total rating power of all
speakers connected to the line must not be greater than that of the
amplifier.
• Connect the black lead "COM" of the speaker to the 100V line that
corresponds to amplifier's terminal marked with "-" / "0" / "com"
• Choose a lead between those differentiated by BLUE/WHITE
colours, depending on the desired power, and connect it to the 100V
line that corresponds to the amplifier's terminal marked with "100V" /
"+".
STEADY IMPEDANCE SYSTEMS
This type of connection does not allow limiting the power of each
speaker individually, because it was designed to obtain greater
performance. The main rule to be observed is that the total impedance
of the speakers is equal to or greater than that of the amplifier. If you
use one speaker, pairing takes place instantly, but if you are using
several speakers, the impedance value will be added or divided
according to the type of connection (series or parallel). As long as you
use just a few speakers, it will be easy to get the 4, 8, 16 Ohms
required by ordinary amplifiers, but if you use more speakers, you will
have to use a combined series/parallel connection to reduce the total
impedance of the loudspeakers to a value that will not be critical for the
amplifier. When carrying out the steady impedance connection, you
should always make sure that the total power of the speakers installed
is greater than that output by the amplifier so as to prevent any
damage due to overload, if the output power is close to the rated
power.
• DO NOT CARRY OUT WITH A 100V LINE.
• Connect the black lead "COM" of the speaker to the amplifier's
terminal marked with "-".
• Connect the lead "RED" (8 Ohm) of the speaker to the amplifier's
terminal marked with "+".

IMPORTANT

FOR SPEAKER CONNECTIONS ONLY TWO
CONDUCTORS ARE USED. IT IS ESSENTIAL TO
INSULATE AND PROTECT THE OTHER TWO
CONDUCTORS NOT USED TO PREVENT THE
MALFUNCTION OF THE SYSTEM.
