Releasethe 4 or 6 screws holding the connector panel (Allen metric 2.5 or TORX20) and disengage the panel &crossover assembly (an upward rotation movement is required).• PS15: On the ICN PCB located near the compression driver.

The technique is to segment the problem by identifying the faulty systemcomponent: 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 systemelements can usually help to isolate and locate the fault.Some cabinet faults can be quite easily located and corrected by the user. A simple sweep with a sinewave generator can be very helpful but it MUST be made at a fairly low level to prevent damage to thespeakers: 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 thecabinet.• Vibrations due to a front grille badly positioned on the quick release fixings.• Some faults require opening the cabinet:• Fuses (refer to above paragraph)• Foreign object that has fallen into the cabinet after repair or through the ports.• Internal connection wires or absorbing material touching the loudspeaker diaphragm: check by removingthe bass loudspeaker (Allen metric N°4).• Loudspeaker not connected or phase reversed following a previous inspection, test or repair.Maintenance & WarrantyNexo loudspeakers and electronics are covered against defects in workmanship or materials for a periodof two (2) years from the original date of purchase.
