-
The speaker input voltage (Vd) shall correspond to the amplifier output voltage (Va).
-
The sum of nominal power values (Pd x n) of all speakers connected to the line shall
not exceed the amplifier power (Pa).
-
Make sure all speakers are connected in phase to ensure a correct sound reproduction.
-
Always use cables having wires with an adequate cross-section, considering the cable
length and the total speaker power.
-
Speaker lines must be kept separated from mains cable, microphone cables or others,
in order to avoid inductive phenomena may cause hum or noises.
-
Use speaker cables having twisted wires to reduce hum caused by inductive effects
due to coupling with electromagnetic fields.
