INPUT CABLES
For connecting the speaker use cables with an adequate cross-section. The greater
the distance between the amplifier and the speaker, the larger the connection cable
cross-section should be to limit the voltage loss along the line.
To prevent inductive phenomena from giving rise to humming or disturbance that
jeopardize the effective operation of the audio system, the speaker cables should not
be run together with electrical energy conductors, microphone cables, or low level
audio lines (e.g. LINE level). To facilitate the ‘’in phase’’ connection of the speaker, use
bipolar cables that have markings to distinguish the polarity (e.g. insulation of different
colours, conductors of different colours, ect.). To minimize the inductive effects (hum)
due to coupling with surrounding electrical fields, use cables with conductors braided
together.
When two speakers reproduce the same frequencies but with phase differences,
these frequencies may be annulled. In sound systems, speakers are often
situated in adjacent positions and the sound waves produced interact with
each other. If a speaker is connected incorrectly; i.e. the polarity of the audio
line conductors is inverted, the audio signals are transmitted with differences
in phase and correct reproduction is therefore jeopardized.
