CONNECTIONS
CONNECTIONS TO THE LOUDSPEAKER LINE ARE MADE BY USING THE 2 WIRE CABLE COMING
OUT FROM THE LOUDSPEAKER REAR SIDE.
1)
Connect the conductor of the audio line that leads from the amplifier terminal marked “
0
” or
‘COW to the
BLACK
conductor of the speaker input cable.
2)
Connect the conductor of the audio line that leads from the amplifier terminal marked “
70V
”
or “
100V
” to the
RED
conductor of the speaker input cable.
3)
Select the output power as described in the section below.
The figure shows a typical application example. To facilitate the “phase” connection of the
speaker, we recommend that you use bipolar cables with markings that distinguish the polarity
(e.g. insulation of different colours, conductors of different colours, etc.). In creating the sound
system at constant voltage, keep the following rules in mind:
1)
The input voltage of the speaker must correspond to the voltage selected on the amplifier
output.
2)
The sum of the nominal power values of all the speakers connected must not exceed that of
the amplifier.
IMPORTANT NOTES
• Two output power values can correspond to a single position of the commutator: one value is
related to the line voltage of 100 V, and the other to the line voltage of 70 V. Pay attention not
to confuse the two values.
• In order to protect the electrical contacts of the commutator and ensure their durability,
we recommend that you change the power value with the system switched off (no sound
programme being diffused), or with the amplifiers adjusted to low volume.
• To prevent breakdowns or malfunctions,
do not turn the commutator to the “70 V” max
power
(last setting turning clockwise) position when the speaker is connected to
lines.
