indicate that no signal is being received and
the SUB-TS7 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 SUB-TS7 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 SUB-TS7’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.
6
§ 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
SUB-TS7. If your receiver has only a single
subwoofer output, you may connect it to
either the left or right line-level input on the
SUB-TS7, and no Y-adapter is needed.
ª Master Power Switch: Place this
switch in the “•” position to power-on the
SUB-TS7 subwoofer. The SUB-TS7 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 SUB-TS7.
The cord should not be plugged into the
accessory outlets found on some audio
components.
¶ Speaker-Level Outputs: If you are
using the Speaker-Level Inputs • on the
SUB-TS7, you should connect these bindingpost terminals to your front left and right
speakers, remembering to maintain polarity
by connecting the (+) terminal on the SUBTS7 subwoofer to the (+) terminal on the
speaker, and the (–) terminal on the SUBTS7 subwoofer to the (–) terminal on the
speaker. If you are not using the SpeakerLevel Inputs •, then connect your front
left and right speakers directly to your receiver
or amplifier. See pages 9 through 12 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 SUB-TS7 subwoofer, and
the (–) terminal on the receiver/amplifier to the
(–) terminal on the SUB-TS7 subwoofer.

OPERATION
Move the Master Power Switch ª
(marked Power) to the “•” (On) position.
The SUB-TS7 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.
Additional Bass Adjustments
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

Subwoofer
Level
MIN

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.
In addition to the volume adjustments
described above, the SUB-TS7 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:
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.
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.

TROUBLESHOOTING
SYMPTOM
SOLUTION
If there is no sound from
any of the speakers:
• Check that receiver/amplifier is on and a source is playing.
• Check that the powered subwoofer is plugged in and its Master Power Switch ª is switched on to the “•” position.
• 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/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.
If the system plays at low
volumes but shuts off as
volume is increased:
• 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 there is low (or no) bass • Make sure the SUB ¡ or Line-Level Inputs § of the SUB-TS7 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 SUB-TS7’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:
14
• 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.

heard and felt from port tube opening.
5) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable.
6) Connect one pair of speaker cables to Speaker Level input terminal (IN) on UUT. Cables should be
connected to an integrated amplifier fed by the signal generator.
7) Turn on generator and adjust so that speaker level input at the amplifier is 1.6V, 50 Hz. Turn LEVEL control
full clockwise.
8) LED should turn from Amber to Blue; immediate and vigorous bass response should be heard and felt from
the port tube opening.
Sweep Function
1) Follow steps 6-8 above, using a sweep generator as a signal source.
2) Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or
any other noises. If any unusual noises are heard, remove woofers and test.
Driver Function
1) Remove woofer from cabinet; detach + and - wire clips.
2) Check DC resistance of woofer; it should be 3.0 ohms ±10%
3) Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier
fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
4) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
