10 MAINTENANCE

Under normal use the amplifier should provide years of trouble-free service. The only maintenance required by the user is to clean the front grille periodically.

In some extreme cases it may be necessary for authorized service personnel to clean the inside of the amplifier. These conditions usually occur after prolonged use, e.g. in environments using "cracked- oil" smoke machines.

If you are using your amplifier for heavy-duty use i.e. concert touring or industrial music it is recommended that you have your amplifier serviced every 3 years, purely as a preventative measure.

10.1 Troubleshooting

These are typical things to check if you think your amplifier is faulty

Fault: No output.

If the Signal Present (-40dB) is illuminating a signal is entering the amplifier and the likely cause is an unsecured Speakon loudspeaker connector, or loose termination.

Check also that the VHF protection is not activated. If it is, remove possible high frequency oscillations from the relevant input

Fault: The amplifier goes into thermal protection when driven at low level.

Check that there is no short circuit present at the amplifier's output, e.g. any component in the loudspeaker (this can occur when the loudspeaker coil gets hot).

Fault: The amplifier goes into protection with power indicators off.

Check that the AC mains voltage is within the amplifier’s operating range, 130-265V@ 230V, and (65- 135V @ 115V). Over/under-voltage protection may have occurred. If the amplifier is connected by mistake to a 3-phase supply, an internal non-resetable fuse or resistor may have blown. The amplifier then has to be returned to your supplier for service.

Fault: The amplifier does not respond even after checking above items.

In the unlikely event of on a non-user rectifiable fault, return the amplifier to your supplier or an approved service centre.
