CONNECTION
Warning:
speaker connections should be only made by qualified and
experienced personnel having the technical know-how or sufficient specific
instructions to ensure that connections are made correctly and to prevent any
electrical danger.
To prevent any risk of electric shock, do not connect speakers when the
amplifier is switched on. Before turning the system on, check all connections
and make sure there are no accidental short circuits.
The entire sound system shall be designed and installed in compliance with
the current local laws and regulations regarding electrical systems.
This speaker can be either linked to 100 V / 70 V constant voltage lines or (if
necessary) its input can be switched to low impedance (8 Ω).
TERMINAL STRIP CONNECTION
Connections with the audio line are made by using the ceramic terminal strip,
which is inside the protective box on the rear side (the cover needs to be
removed).
The + / – terminals allow to connect both input and output cables (to link
other speakers in parallel).
Applicable wire section: from 1 mm² to 4 mm².
1.
Insert cables through the two rear cable guides.
2.
Connect the line positive wire to the s input.
3.
Connect the line negative wire to the speaker – input.
4.
If necessary, connect in the same way the output cable to link other
speakers in parallel.

:
-
Make sure all speakers are connected in phase to ensure a correct sound
reproduction.
-
Always use cables having wires with an adequate cross-section,
considering the cable length and the total speaker power.
-
Speaker lines must be kept separated from mains cable, microphone
cables or others, in order to avoid inductive phenomena may cause hum
or noises.
-
Use speaker cables having twisted wires to reduce hum caused by
inductive effects due to coupling with electromagnetic fields.
