22、ontrol.Turn the control clockwise to increase the Subwfr volume, or counterclockwise to decrease it. High-Cut (Low-Pass) Filter Switch:Placing switch in the ON position activatescircuitry that cuts out all audio input signalsabove 120Hz.This allows the Subwfr to focus its power on reproducing the lo

23、w-frequency portion of the signal, avoiding inefficiency and distortion. Engage this filterwhen using the Speaker-Level Inputs ,or when using the Line-Level Full-RangeInputs , unless your receiver or processorprocesses its line-level output using a low-pass filter.The filter has no effect when theSU

24、B Input is used. Music-Sense On/Off Switch:Whenplaced in the AUTO position,and when theMaster Power Switch is turned on,theSubwfr will automatically turn itself on orplace itself in the Standby mode,depending onwhether it is receiving an audio signal.Whenthis switch is placed in the ON position,theS

25、ubwfr will remain on,whether or not it isreceiving an audio signal.An LED located on top of the Subwfr indi-cates whether the Subwfr is in the ON orSTANDBY state when used with the Music-Sense On/Off Switch in the AUTOposition.The LED is lit blue to indicate thatthe Subwfr is receiving an audio sign

28、ue, whether or not an audio signal is present.When the Master Power Switch isturned off, the LED goes dark, no matterwhich position the Music-Sense On/OffSwitch is in. Phase Switch: This switch determineswhether the subwoofers piston-like action moves in and out in phase withthe main speakers. If th

29、e speakers were toplay out of phase, the sound waves pro-duced by the subwoofer would be cancelledout, reducing bass response.This phenome-non depends in part on the relative place-ment of the speakers in the room. In mostcases, the Phase Switch should be leftin the NORMAL position. However, itdoes

30、no harm to experiment with the PhaseSwitch , and you may leave it in theposition that maximizes bass response. Line-Level Subwoofer (SUB) Input:Connect the subwoofer output of a receiverwith digital surround sound decoding, suchas Dolby* Digital or DTS, to this input.Thisinput bypasses the Subwfrs i

31、nternalcrossover circuitry, and should only be usedwith a filtered signal. If your receiver does nothave digital decoding,you should use theLine-Level Full-Range Inputs instead. Line-Level Full-Range Inputs: Connectthe line-level subwoofer output or preamp out-put(s) of your receiver or amplifier to

32、 theseinputs.If your receiver does not have a sepa-rate subwoofer output,use a Y-adapter (notsupplied) to bridge the receivers preamp out-put to the main amp input for that channel,and connect the long end of the adapter to the corresponding line-level input on theSubwfr.If your receiver has only a

33、singlesubwoofer output,you may connect it to either the left or right line-level input on theSubwfr,and no Y-adapter is needed. Speaker-Level Outputs: If you areusing the Speaker-Level Inputs on theSubwfr, you should connect these binding-post terminals to the front left and rightspeakers, rememberi

34、ng to maintain polarityby connecting the (+) terminal on the subwoofer to the (+) terminal on the speaker, and the () terminal on the subwoofer to the () terminalon the speaker. If you are not using theSpeaker-Level Inputs , then connectyour front left and right speakers directly to your receiveror

35、amplifier. See pages 8 for further information on speaker connections. Speaker-Level Inputs: Connect thesebinding-post terminals to the main left andright speaker terminals of your receiver oramplifier, if your receiver or amplifier doesnot have a line-level subwoofer output.Remember to maintain pol

36、arity by connectingthe (+) terminal on the receiver/amplifier to the(+) terminal on the subwoofer,andthe () terminal on the receiver/amplifier to the() terminal on the subwoofer. Master Power Switch: Place thisswitch in the “” position to power-on the subwoofer.The Subwfr will thenbe either in the S

37、tandby mode or completelyon, depending on the position of the Music-Sense On/Off Switch . AC Power Cord: Make sure to plug this cord into an active, unswitched electrical out-let for proper operation of the Subwfr.The cord should not be plugged into theaccessory outlets found on some audiocomponents
