-
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).
-
The total loudspeaker impedance must not be lower than the amplifier
output impedance. A loudspeaker total impedance equal to the amplifier
output one permits to get the maximum deliverable power (but an higher
loudspeaker impedance entails less power).
-
The total loudspeaker power shall be adequate for the maximum
deliverable power of the amplifier.
-
The loudspeaker line shall be short (for long distances, it may be necessary
to use cables with large cross-section wires).
-
Do NOT connect the low impedance input directly to 70 / 100 V constant
voltage lines.
