¡ Subwoofer-Level Control: Volume may be adjusted using the Subwoofer-

Level Control. 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 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

An LED located on top of the

Subwfr indicates whether the

Subwfr is in the ON or

harman/kardon 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 Music-

Sense 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.

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 Music-

Sense 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

Additional Bass Adjustments

In addition to the volume adjustments described above, the

Subwfr subwoofer includes a Phase Switch ¢ and a Filter

Switch ™ 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

™ 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.
