- The total loudspeaker power shall be adequate for the maximum
deliverable power of the amplifier.
- The loudspeaker line length shall be short (for long distances, it may be
necessary to use cables with large cross-section wires).
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 "+".

- 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.
