SYSTEM CONNECTIONS If you have a Dolby® Digital or DTS® receiver/processor with a low-frequencyeffects (LFE) or subwoofer output:
If your receiver/processor does not have subwoofer outputs for the left and right channels or an LFE output, connect speaker wire from your receiver/ amplifier to your speakers and subwoofer using two sets of speaker wire:

OPERATION Power On Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver.
Initially set the Subwoofer-Level Control ¢ to the “min” position. Turn on your sub by pressing the Power Switch ª on the rear panel. Turn on your entire audio system and start a CD or movie soundtrack at a moderate level. Auto On/Standby
With the Power Switch ª in the “on” position, the Power Indicator LED ∞ will remain backlit in red or green to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected, Amp Off) GREEN = ON (Signal detected, Amp On) When the Auto Switch § is in the “auto” position, the subwoofer will automatically enter the Standby mode after approximately 10 minutes when no signal is detected from your system. The subwoofer will then power ON instantly when a signal is detected. During periods of normal use, the Power Switch ª may be left on. You may turn off the Power Switch ª for extended periods of non-operation, e.g., when you are away on vaca tion. If the Auto Switch § is in the “on” position, the subwoofer will remain on. Adjust Gain Turn your Subwoofer-Level Control ¢ up to the halfway position. If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact? Is the AC plug connected to a “live” receptacle? Has the Power Switch ª been pressed to the “on” posi tion? Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information.
Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the Subwoofer-Level Control ¢ until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. This is not entirely true. A
The enclosure may be cleaned using a soft cloth to remove fingerprints or to wipe off dust. The grille may be gently vacuumed. Stains may be removed with an aerosol cleaner, following its instructions. Do not use any solvents on the grille.
