Status LED: Indicates the subwoofer’s operational status:
• Lights blue continuously when the subwoofer is on and linked to
the soundbar.
• Slowly flashes blue when the subwoofer is on and the wireless link
is not established between the subwoofer and the soundbar.
• Rapidly flashes blue during the wireless pairing process.
• Lights amber continuously when the subwoofer is in the Standby
mode.
• Turns off when the subwoofer’s Power switch is in the “Off”
position.
Level Control: Use this control to balance the subwoofer’s volume
with that of the soundbar. Turn the knob clockwise to increase
the subwoofer’s volume; turn it counterclockwise to decrease the
subwoofer’s volume.
Cutoff Control: This knob adjusts the subwoofer’s cutoff between
40Hz and 200Hz.The higher you set the Cutoff control, the higher
in frequency the subwoofer will operate and the more its bass will
“overlap” that of the soundbar. This adjustment helps achieve a
smooth transition of bass frequencies between the subwoofer and the
soundbar for a variety of different rooms and subwoofer locations. See
Subwoofer Cutoff Control, on page 7, for more information.
Phase Switch: This switch determines whether the subwoofer driver’s
piston-like action moves in and out in phase with the speakers in
the soundbar. If the subwoofer were to play out of phase with the
soundbar speakers, some of the sound waves produced by the
subwoofer or soundbar could be canceled, reducing bass performance
and sonic impact. This phenomenon depends in part on the relative
placement of the speakers in the room. See Subwoofer Phase Switch,
on page 7, for more information.
Wireless Pairing Switch: Press this switch to initiate wireless pairing
between the subwoofer and the soundbar. See Pairing the Units for
Wireless Operation, on page 6, for more information.
Power Switch: Set this switch to the “On” position to activate the
subwoofer. In normal operation, this switch will be left in the “On”
position. See Turning the Subwoofer On and Off, on page 6, for more
information.
If you will not be using the subwoofer for an extended period – for
instance, if you’re going on vacation – set the Power switch to the
“Off” position.
Power Cord Connector: Connect the included power cord here and
into an active, unswitched AC outlet. See Power Connections, on page
5, for more information.
IMPORTANT: Do not connect the power cord to an AC outlet until you
have made and verified all other connections.

CONNECTIONS
Use the supplied stereo audio cable to connect the
soundbar’s Source 1 (analog) input to your TV’s stereo audio output.
If your TV has two sets of audio output jacks, use the set that has
a fixed (not variable) output level. This will let you turn your TV’s
speakers all the way off while the TV still supplies a constant audio
signal to the soundbar.
If your DVD player, cable tuner or satellite tuner has an optical
digital output, you can use an optical digital audio cable to connect it
to the soundbar’s Source 2 (optical digital) input.
NOTE: If your DVD player, cable tuner or satellite tuner does not have
an optical digital output, you can connect its analog audio output to
your TV. The TV will send its audio signal to the soundbar through the
analog connection described above.
After verifying that all of the source connections have been made
properly, plug the supplied power cords into the soundbar’s and
subwoofer’s Power Cord connectors, and plug the other ends into
active, unswitched AC outlets. Do NOT plug these cords into the
accessory outlets found on some audio components.

gone into the Standby mode 15 minutes after the audio signal has
ceased, it will automatically turn itself on when it receives an audio
signal at either the analog (Aux) input or the optical digital input.
Set the subwoofer’s Power switch to the “On” position. The
subwoofer will automatically attempt to establish pairing with the
soundbar (the subwoofer’s LED will flash blue). If pairing is not
established within one minute, the subwoofer will enter the Standby
mode (its LED will turn amber). If pairing is established, the subwoofer
will turn on (its LED will light blue continuously).
The subwoofer will remain on for approximately one minute after the
soundbar enters the Standby mode, or for approximately 15 minutes
after the audio signal ceases.

Use the subwoofer’s Level knob to balance the bass with the rest of
the sound. Play music or movies that you are familiar with, and adjust
the subwoofer’s Level knob so the bass sounds balanced on both
music and films. Listen to several different music recordings and film
soundtracks that contain strong bass passages, and find a setting for
the Level knob that doesn’t over-emphasize the bass or make it sound
weak.
Level

MAX
Once you find a setting for the subwoofer’s Level knob that balances
the bass with the rest of the sound, you shouldn’t have to change it.
The subwoofer’s Cutoff control adjusts the subwoofer’s cutoff
between 40Hz and 200Hz. The higher you set the Cutoff control, the
higher in frequency the subwoofer will operate and the more its bass
will “overlap” that of the soundbar. This adjustment helps achieve a
smooth transition of bass frequencies between the subwoofer and the
soundbar for a variety of different rooms and subwoofer locations.
Cutoff
40Hz
200Hz
To set the Cutoff control, listen for the smoothness of the bass. If the
bass seems too strong at certain frequencies, try a lower Cutoff control
setting. If the bass seems too weak at certain frequencies, try a higher
Cutoff control setting.
This switch determines whether the subwoofer’s piston-like action
moves in and out in phase with the speakers in the soundbar.
If the subwoofer were to play out of phase with the soundbar
speakers, some of the sound waves produced by the soundbar and
subwoofer could be canceled out at some frequencies, reducing bass
performance and sonic impact. This phenomenon depends in part on
the relative placement of the soundbar and subwoofer in the room.
Phase
0° 180°
Although there is no absolutely correct setting for the Phase switch, in
most cases it should be left in the “0°” position. When the subwoofer
is properly in phase with the soundbar speakers, the sound will be
clearer and have more impact. It will make percussive sounds like
drums, piano and plucked strings sound more lifelike. The best way
to set the Phase switch is to listen to music that you are familiar with
and adjust the switch so that drums and other percussive sounds have
maximum impact.

NOTE if amplifier repair involves the removal of the Control PCB:
after the four Phillips machine screws on the faceplate are removed, three
foam tubes need to be pried away from the faceplate in order to access any
of its components with the exception of the wireless module U3. Care
should be taken to do minimal damage to the foam, as these preserve the
air integrity at the openings of the LED and phase & pairing switches. If
these foam tubes are damaged and air is allowed to pass through these
openings upon reassembly, it could affect the performance of the
subwoofer and the escaping air might be audible. Upon reassembly, small
amounts of silicon sealer can be used to assure the foam tubes adhere to
the faceplate as designed.
