- 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)�
- Make sure all loudspeakers 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 loudspeaker power�
- oudspeaker lines must be kept separated from mains cable, microphone cables or others, in order to avoid inductive phenomena may cause
hum or noises�
- Use loudspeaker cables having twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields�
