¡ Subwoofer-Level Control: Volume may be adjusted using the SubwooferLevel Control. Turn the control clockwise to increase the Subwfr volume, or counterclockwise to decrease it. TM High-Cut (Low-Pass) Filter Switch: Placing switch in the ON position activates circuitry that cuts out all audio input signals above 120Hz. This allows the Subwfr to focus its power on reproducing the lowfrequency portion of the signal, avoiding
inefficiency and distortion. Engage this filter when using the Speaker-Level Inputs ·, or when using the Line-Level Full-Range Inputs §, unless your receiver or processor processes its line-level output using a lowpass filter. The filter has no effect when the SUB Input is used. £ Music-Sense On/Off Switch: When placed in the AUTO position, and when the Master Power Switch ª is turned on, the Subwfr will automatically turn itself on or
place itself in the Standby mode, depending on whether it is receiving an audio signal. When this switch is placed in the ON position, the Subwfr will remain on, whether or not it is receiving an audio signal. An LED located on top of the Subwfr indicates whether the Subwfr is in the ON or STANDBY state when used with the MusicSense On/Off Switch £ in the AUTO position. The LED is lit blue to indicate that the Subwfr is receiving an audio signal

and is turned on, and the LED is lit amber to indicate that no signal is being received and the Subwfr is in Standby mode. When the Music-Sense On/Off Switch £ is in the ON position, the LED will be lit blue, whether or not an audio signal is present. When the Master Power Switch ª is turned off, the LED goes dark, no matter which position the Music-Sense On/Off Switch £ is in. ¢ Phase Switch: This switch determines whether the subwoofer's pistonlike action moves in and out in phase with the main speakers. If the speakers were to play out of phase, the sound waves produced by the subwoofer would be cancelled out, reducing bass response. This phenomenon depends in part on the relative placement of the speakers in the room. In most cases, the Phase Switch ¢ should be left in the NORMAL position. However, it does no harm to experiment with the Phase Switch ¢, and you may leave it in the position that maximizes bass response. Line-Level Subwoofer (SUB) Input: Connect the subwoofer output of a receiver with digital surround sound decoding, such as Dolby* Digital or DTS® to this input. This , input bypasses the Subwfr's internal crossover circuitry, and should only be used with a filtered signal. If your receiver does not have digital decoding, you should use the Line-Level Full-Range Inputs § instead. § Line-Level Full-Range Inputs: Connect the line-level subwoofer output or preamp output(s) of your receiver or amplifier to these inputs. If your receiver does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver's preamp output to the main amp input for that channel, and connect the long end of the adapter to the corresponding line-level input on the Subwfr. If your receiver has only a single subwoofer output, you may connect it to either the left or right line-level input on the Subwfr, and no Y-adapter is needed. ¶ Speaker-Level Outputs: If you are using the Speaker-Level Inputs · on the Subwfr, you should connect these bindingpost terminals to the front left and right speakers, remembering to maintain polarity by connecting the (+) terminal on the subwoofer to the (+) terminal on the speaker, and the () terminal on the subwoofer to the () terminal on the speaker. If you are not using the Speaker-Level Inputs ·, then connect your front left and right speakers directly to your receiver or amplifier. See pages 8 for further information on speaker connections. · Speaker-Level Inputs: Connect these binding-post terminals to the main left and right speaker terminals of your receiver or amplifier, if your receiver or amplifier does not have a line-level subwoofer output. Remember to maintain polarity by connecting the (+) terminal on the receiver/amplifier to the (+) terminal on the subwoofer, and the () terminal on the receiver/amplifier to the () terminal on the subwoofer. ª Master Power Switch: Place this switch in the "·" position to power-on the subwoofer. The Subwfr will then be either in the Standby mode or completely on, depending on the position of the MusicSense On/Off Switch £. , AC Power Cord: Make sure to plug this cord into an active, unswitched electrical outlet for proper operation of the Subwfr. The cord should not be plugged into the accessory outlets found on some audio components.

USE THIS INSTALLATION METHOD FOR DOLBY PRO LOGIC APPLICATIONS (NOT DOLBY DIGITAL, DTS OR OTHER DIGITAL PROCESSING), WHERE THE RECEIVER/ PROCESSOR IS EQUIPPED WITH A SUBWOOFER OUTPUT, OR A VOLUMECONTROLLED PREAMP (LINE-) LEVEL OUTPUT: Use the supplied RCA-type interconnect cable to connect the line-level subwoofer output on your receiver or amplifier to either the left or right Line-Level Full-Range Input § on the subwoofer. Use both the left and right inputs on the subwoofer if your receiver or processor has both left and right line-level outputs. In that case, you will need to supply a second interconnect cable. If your receiver is equipped with line-level outputs but does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver's preamp output to the main amp input for that channel, and connect the long end of the adapter to the corresponding line-level input on the Subwfr. IMPORTANT: Do not use the SUB Input on the subwoofer with Dolby Pro Logic processors. If your receiver/processor has a built-in lowpass-crossover filter for the subwoofer output, you may use the SUB Input to bypass the subwoofer's internal crossover. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure that you have configured your surround sound processor for "Subwoofer On.

OPERATION
Move the Master Power Switch ª (marked Power) to the "·" (On) position. The Subwfr subwoofer will automatically turn itself on or go into Standby mode, depending on whether or not a signal is being sent to it by your receiver or surround processor, and provided that the MusicSense On/Off Switch £ is moved down so that it is in the AUTO position. When your receiver or amplifier is off, or is not sending program material to the subwoofer, the subwoofer will be in Standby mode and the LED Indicator on the top of the subwoofer will turn amber. When the subwoofer senses an audio signal, it will automatically turn itself on and the LED Indicator will turn blue. If the subwoofer does not sense a signal after approximately twenty minutes, it will automatically go into Standby mode. When the Music-Sense On/Off Switch £ is switched to the ON position, the subwoofer will remain on, whether or not program material is playing, and the LED Indicator will remain lit blue. If you'll be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power Switch ª to the OFF position. Volume Volume can be adjusted using the Subwoofer-Level Control ¡, as shown. Turn the control knob clockwise to increase the volume of the subwoofer, and counterclockwise to decrease the subwoofer's volume.
Subwoofer Level
Additional Bass Adjustments In addition to the volume adjustments described above, the Subwfr subwoofer includes a Phase Switch ¢ and a Filter Switch TM that can be used to adjust the bass response to suit your listening environment or taste. In most situations, the Phase Switch ¢ should be left in the NORMAL position. If you suspect that the subwoofer is playing out of phase with the other speakers, which would tend to diminish bass response, try placing this switch in the REVERSE position. There is no harm in experimenting, and you may return the switch to the NORMAL position at any time. If you rearrange your room and reposition the speakers, it would be a good idea to check whether they are in phase by flipping this switch. The High-Cut (Low-Pass) Filter Switch TM limits the frequencies of the audio signal inputted to the subwoofer to the low frequencies that the subwoofer reproduces best. This allows the subwoofer to perform more efficiently, and with superior bass reproduction, minimizing distortion that might occur if the subwoofer attempted to reproduce higher frequencies. This switch should be left in the ON position, except: 1. When the SUB Input is being used, in which case it has no effect, or 2. When the Speaker-Level Inputs · or the Line-Level Full-Range Inputs § are being used with a crossover or filter aboard the receiver or processor. In these two circumstances, place the switch in the OFF position.

Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, punctured, or touching other wires. · Review proper operation of your receiver/amplifier.
If there is no sound coming · Check the "Balance" control on your receiver/amplifier. from one speaker: · Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured, and that no wires are touching each other. · In Dolby Digital or DTS mode, make sure that the receiver/processor is configured so that the speaker in question is enabled. · Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem is in the same place: i.e., the speaker that was working previously now has no sound and the speaker that was not working now sounds fine; or whether it has moved: i.e., the speaker that was not working still has no sound and the speaker that was working is still fine. If the problem is in the same place, the source of the problem is most likely with your receiver or amplifier, and you should consult the owner's manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit our Web site at www.harmankardon.com for further information. If there is no sound from the center speaker: · Check all wires and connections between receiver/amplifier and speaker. Make sure all wires are connected. Make sure none of the speaker wires are frayed, ccut, punctured, or touching other wires. · If your receiver/processor is set in Dolby Pro Logic mode, make sure the center speaker is not in phantom mode. · If your receiver/processor is set in Dolby Digital or DTS mode, make sure the receiver/processor is configured so that the center speaker is enabled. · Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, punctured, or touching other wires. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.
If the system plays at low volumes but shuts off as volume is increased:
If there is low (or no) bass · Make sure the SUB ¡ or Line-Level Inputs § of the subwoofer and SUB or LFE output of your receiver output: or amplifier are properly connected by the RCA-type interconnect cable. · If you are using the Subwfr's Speaker-Level Inputs ·, check your speaker cables to make sure they are all connected; that none of the wires are frayed, cut, punctured, or touching other wires; and that you have maintained the correct polarity by connecting positive terminals to positive terminals, and negative terminals to negative terminals. · Make sure the subwoofer is plugged into an active electrical outlet and its Master Power Switch ª is switched on to the "·" position. · Check the speaker setup (bass management) settings in your A/V receiver or processor to make certain that the front, center and surround speakers are configured for "Small," and that the subwoofer is set for "Yes" or "On." If there is no sound from the surround speakers: · Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, punctured, or touching other wires. · Review proper operation of your receiver/processor and its surround sound features. · Make sure the movie or TV show you are watching is recorded in a surround sound mode. If it is not, check to see whether your receiver/processor has other surround modes you may use. · In Dolby Digital or DTS mode, make sure your receiver/processor is configured so that the surround speakers are enabled. · Review the operation of your DVD player and the jacket of your DVD to make sure that the DVD features the desired Dolby Digital or DTS mode, and that you have properly selected that mode using both the DVD player's menu and the DVD disc's menu.
