LFE is a band limited (less than 120 Hz) channel that reproduces decoded information from a 5.1 source. The LFE output can be used to send a signal to a second subwoofer. hi-pass output: An optional output to a 2nd receiver with it’s own speakers. AC power connection: Power cable connection. maintenance Normal maintenance of the subwoofer consists of keeping the unit clean and dust-free. Use a soft cloth or brush to remove dust without scratching or marring the finish. Do not use strong cleaner or solvents of any kind. Avoid spray cleaners or waxes. They can produce spotty glossy areas. Keep moisture away from the subwoofer. Avoid the temptation to place a plant that needs watering on top of the subwoofer. If any part of the subwoofer gets wet, IMMEDIATELY unplug the power cord from the wall. Then clean up the moisture. If you suspect moisture has gotten inside the subwoofer or its amplifier, contact your authorized a/d/s/ dealer for service support. voltage conversion The subwoofer amplifier can be set to operate at 115 or 230 volts by using the voltage switch on the control panel of the amplifier. in case of difficulty Loose connections, defective connecting cables or improper operation causes most difficulties with high fidelity equipment. Often, problems show up after a change is made to the system or after the system has been moved. Carefully check all connections. Before you disconnect any equipment label all connecting cables and wires so you can reconnect them properly. Some common difficulties and suggested remedies are described below. If these steps do not correct the problem, contact your a/d/s/ dealer for assistance. If you want to contact the factory, write or call the a/d/s/ Technical Service Department at: Directed Electronics Inc. 1 Viper Way Vista, CA 92081 800-753-0800 ext. 2032 Technical Service is open from 6:30am to 5:30pm PST. With some program material it may be difficult to hear the subwoofer, especially at low volume levels. Turn up the volume control or the bass tone control to make the deep bass sound more obvious. Popular, electronically produced music has more bass energy than acoustic music and will make the sound of the subwoofer more prominent. Buzzes and rattles: Locate the source of the noise and secure it. Place pads under loose objects that rattle or vibrate. Noises may occur in adjacent rooms because low frequency sound can be mechanically transmitted through walls and floors. No power: Check the AC power connection of the subwoofer amplifier. Check all switches and fuses or circuit breakers, which control the outlet into which the subwoofer is plugged in to. Do not plug the subwoofer into an outlet controlled by a dimmer. Test the power outlet by plugging a normal lamp into it to see if the outlet is active. Examine the plug and cord for damage. If the plug or cord shows any signs of damage or wear do not use it. Contact an a/d/s/ service agency or the factory to get a replacement. No sound: Check the audio cables connected to the inputs of the subwoofer. Check the amplifier tape monitor switches to be sure that they are set properly. If the high level inputs of the subwoofer are being used make sure the speaker outputs driving them are switched on. No deep bass or intermittent bass: The subwoofer amplifier circuitry detects operating conditions that could damage the amplifier or the speaker. This circuitry can turn of the amplifiers output until the overload condition has pa...
