The loudspeaker cable shall have wires with a suitable section (twisted, if
possible, to reduce inductive effects due to surrounding electro-magnetic
fields) and a sufficient electrical insulation. The greater the distance between
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, all power rates will be halved (10 – 5 – 2.5 W).
NOTES:
-
The loudspeaker input voltage (Vd) shall correspond to the amplifier output
voltage (Va).
-
The sum of nominal power values (Pd x n) of all loudspeakers connected to
the line shall not exceed the amplifier power (Pa).
