CONNECTIONS AND PRESETTING
Warning:
loudspeaker 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) in order to
prevent any electrical danger.
To prevent any risk of electric shock, do not connect loudspeakers 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.
If the loudspeaker is installed outdoor (IP 66), all electrical connections shall
be inside weatherproof boxes / wall niches.
Connect its white wire to the line coming from the amplifier 100 V output (or
70 V); connect its black wire to line coming from the amplifier common output
(or 0, b, ––).
The internal transformer allows the connection to 100 V (/ 70 V) constant
voltage lines and the power selection (during the installation) among 30 W,
20 W, 10 W, 5 W (half power if using 70 V lines). It is possible to select the low
impedance (8 Ω) connection as well.
The power selection is made (by using a screw driver) through a rotary
commutator , which is normally protected by a rubber cover (that must be
removed momentarily).
Once the selector has been tapped, insert the rubber cover again.
