-
The total loudspeaker impedance must not be lower than the amplifier
output impedance.

-
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).
-
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.
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 “+”.
