High-Cut (Low-Pass) Filter Switch:Placing th

22、is switch in the ON position acti-vates circuitry that cuts out all audio inputsignals above 120Hz, allowing the SUB-TS11to focus its power on reproducing the low-frequency portion of the signal, avoiding inef-ficiency and distortion. Engage this filterwhen using the Speaker-Level Inputs ,or when us

23、ing 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 theSUB Input is used. External Trigger Input: Use the sup-plied mini-plug cable to connect the triggeroutput of another product to this jack.Wh

24、ena trigger signal between 3 and 30 volts (ACor DC) is detected, the SUB-TS11 amplifierwill turn on, even when the Audio-Sense feature has been activated by placing theAudio-Sense On/Off Switch in theAUTO position.The amplifier will remainon for about 1015 minutes without anaudio signal.

28、osition.The LED is lit blue to indicate thatthe SUB-TS11 is receiving an audio signaland is turned on, and the LED is lit amber toindicate that no signal is being received andthe SUB-TS11 is in the Standby mode.When the Audio-Sense On/Off Switch is in the ON position, the LED will be litblue, whethe

29、r or not an audio signal is present.When the Master Power Switch isturned off, the LED goes dark, no matterwhich position the Audio-Sense On/OffSwitch is in. Phase Switch: This switch determineswhether the SUB-TS11 subwoofers piston-like action moves in and out in phase withthe main speakers. If the

30、 speakers were toplay out of phase, the sound waves pro-duced by the subwoofer would be canceledout, 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 no

31、 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 DolbyDigital or DTS, to this input.Thisinput bypasses the SUB-TS11s int

32、ernalcrossover 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 t

33、heseinputs.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 theSUB-TS11.If your receiver has only a

34、singlesubwoofer output,you may connect it to either the left or right line-level input on theSUB-TS11,and no Y-adapter is needed. Speaker-Level Outputs: If you areusing the Speaker-Level Inputs on theSUB-TS11, you should connect these bind-ing post terminals to your front left and rightspeakers, rem

If you are not using theSpeaker-Level Inputs , then connectyour front left and right speakers dire

36、ctly to your receiver or amplifier. See pages 9through 12 for further information on speakerconnections. Speaker-Level Inputs: If your receiveror amplifier does not have a line-level sub-woofer output, connect these binding-postterminals to the main left and right speakerterminals of your receiver o
