6. Service

If the product seems to be not operating correctly,
before contacting the service centre, carry out all the
tests the may confirm the malfunction. In many pro-
ducts taken to the service centre, it is not possible to
reproduce the malfunction indicated because the pro-
blem is probably to be found elsewhere in the sound
system. If the product does require service, place it in
its original packaging and take it to your local dealer
or to the nearest service centre.
7. Appendix A- Input cables
For connecting the speaker use cables with an ade-
guate cross-section. The greater the distance
between the amplifier and the speaker, the larger the
connection cable cross-section should be.
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 con-
ductors, 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 cou-
pling with surrounding electrical fields, use cables
with conductors braided together.
