The LED should then go off. See Section 6.1.2 for other LED indications.

If it is desired to completely power off (de-energize) the loudspeaker, a conveniently located AC mains disconnect must be supplied or the power cable must be unplugged from the loudspeaker or the AC mains supply.

The PowerCon connector is a locking connecter. To lock, twist 1/4 turn clockwise after fully inserting into the jack. It is recommended the connection be made at the loudspeaker before connection to the AC mains supply.

If excessive AC mains input current is detected, the replaceable fuse will blow. This can occur for a variety of reasons, such as internal failure, excessive AC mains voltage, or excessive amplifier output levels.

If the fuse blows, replace it only with a fuse of the correct type and rating as listed below. In the unlikely event the fuse blows again, inter- nal failure is indicated. This will require troubleshooting and repair by a qualified service technician. Do not attempt further use of the loudspeaker until such repairs are made. See Section 8.2 “Troubleshooting”.

The Audio Ground Lift switch may help isolate audio ground loops. This dip switch disconnects the shield pins on all the audio connectors from the internal audio ground. This affects the audio shield pins on the Audio A and Audio B connectors. Use this switch as needed for reducing ground loop noise.
