ENGLISH
13. To prevent inductive effects from causing hum, noise and a bad system
working, loudspeaker lines should not be laid together with other electric
cables (mains), microphone or line level signal cables connected to amplifier
inputs.
14. The loudspeaker cable shall have wires with a suitable section (twisted,
if possible, to reduce inductive effects due to surrounding electro-magnetic
fields) and a sufficient electrical insulation.
