POWER SELECTION
Connect the positive wire (100 V) to the loudspeaker input corresponding to
the chosen power rate among 20W – 10W – 5W. Connect the negative wire
(0) to the COM loudspeaker input.
If connecting to a 70 V line, all power rates will be halved (10 – 5 – 2.5 W).
ENGLISH
131.33.074
DIMENSIONS
- The loudspeaker cable shall have wires with a suitable section (twisted, if
possible, to reduce inductive effects due to surrounding electro-magnetic
fields)
and are
a sufficient
electrical insulation. The greater the distance between
(All
data
in mm)
the amplifier and the speaker, the larger the connection cable cross-section
should be to limit the voltage loss along the line.
Connect the positive wire (100 V) to the loudspeaker input corresponding to
the chosen power rate among 20W – 10W – 5W.
Connect the negative wire (0) to the COM loudspeaker input.
If connecting to a 70 V line,
100all power rates will be halved (10 – 5 – 2.5 W).

CERTIFICATIONS AND APPROVALS
• EN 54-24:2008 compliant
To ensure a correct musical reproduction, loudspeaker phase is to be
respected (loudspeakers are connected respecting the amplifier polarity).
To prevent inductive effects from causing hum, noise and a bad system
working, loudspeaker lines should not be laid together with other electric
cables (mains), microphone or line level signal cables connected to amplifier
