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 Music-
Sense 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

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.

, to this input. This

§ 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

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

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 out-

let 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
sub

woofer 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
minutes,

it will automatically go into Standby

approximately twenty

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

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.

•

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 further information. If the
possible, visit our Web site at www.harmankardon.com for further information.
