TROUBLESHOOTING
Simple troubleshooting does not require sophisticated measurement equipment and can be easily
undertaken by users. The technique should be to segment the system in order to identify the faulty system
component: signal source, controller, amplifier, loudspeaker or cable? Most installations are multi-channel. It is
often the case that one channel works and others do not. Trying different combinations of system elements can
usually help to isolate and locate the fault.
Some cabinet faults can be quite easily identified and corrected by the user. A simple sweep with a sine
wave generator can be very helpful though it MUST be made at a fairly low level to prevent damage to the speakers.
A sine wave sweep can help find:
•
Vibrations due to loose screws.
•
Air-leak noises: check that no screws are missing, particularly where the accessories attach to the cabinet.
•
Vibrations due to a front grille badly positioned on the quick release fixings.
•
Foreign object that has fallen into the cabinet after repair or through the ports.
•
Internal connection wires or absorbing material touching the loudspeaker diaphragm.
•
Loudspeaker not connected or phase reversed following a previous inspection, test or repair.
