INPUT CONNECTOR

Connect the line negative wire (coming from the amplifier output
"0", "COM" or "–") to one of the 2 subwoofer inputs "–".
Connect the line positive wire (amplifier output: "100 V", "70 V" or "+")
to one of the 2 subwoofer inputs "+".
Note: the remaining inputs "+" and "–" can be used for the parallel
connection of other loudspeakers / subwoofers.

OTHER NOTES

• Always use cables having wires with an adequate cross-section, considering
the cable length and the total loudspeaker power.
• Loudspeaker lines must be kept separated from mains cables, microphone
cables or others, in order to avoid inductive phenomena may cause hum or
noises.
• Use cables with twisted wires to reduce hum caused by inductive effects
due to coupling with electromagnetic fields.
