CONNECTIONS
WARNING: loudspeaker connections should only be 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 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.
The internal transformer allows the connection to 100 V constant voltage
lines and the power selection (during the installation) among the values
20 W - 10W - 5 W.
The selection is made considering the wire colours.
COLOUR POWER VOLTAGE IMPEDANCE
RED 20 W 100 V 500 Ω
YELLOW 10 W 100 V 1000 Ω
GREEN 5 W 100 V 2000 Ω
BLUE common wire
Connect the loudspeaker BLUE wire to the line coming from the amplifier terminal
marked with “–”, “0” or COM.
Choose one of the three wires (according to the power) among RED (20 W),
YELLOW (10 W) or GREEN (5 W) and connect it to the amplifier 100 V line
terminal.
The connection to the 70 V terminal (if available on the amplifier) allows you to
get half of the power mentioned in the table above. The relevant SPL as well will
be consequently reduced.
