PLaciNg tHe sOuNdBar ON a taBLe
If your TV is placed on a table, you can place the soundbar on the
table directly in front of the TV stand, centered with the TV screen.
As long as the surface of the table is flat, the soundbar will rest on its
rubber bumpers.
WaLL-MOuNtiNg tHe sOuNdBar
If your TV is attached to a wall, you can use the included wall-mount
brackets to mount the soundbar on the wall directly below the TV
screen.
1. Determine the location for the soundbar on the wall. Make sure
that the top of the soundbar will not block your view of the TV
screen when it is mounted on the wall.
2. Mark the locations of the soundbar wall-mount bracket holes on
the wall. The holes for the left and right brackets are spaced
30-5/16” (770mm) apart, and are designed to accept 4mm
diameter screws. The top and bottom holes for each bracket are
spaced 1” (25mm) apart. See the illustration below.
30-5/16" (770mm)
1" (25mm)
(not to scale)
NOTE: To ensure that the soundbar will be level, use a carpenter’s
level, laser sight or other device to ensure that the two sets of holes
are at exactly the same height.
3. Attach the two wall-mount brackets to the wall at the locations
you marked, using hardware that is appropriate for the wall’s
construction and materials. Note that the soundbar weighs 2.5kg
(5.5 lb). Be sure to use hardware that can support this weight.
4. After making all of the connections described in the
Connections
section, on page 5, attach the soundbar to the brackets by sliding
the brackets’ vertical tabs into the slots in the soundbar’s rubber
bumpers.

The performance of a subwoofer is directly related to its placement
in the listening room and its physical position relative to the other
speakers in the system.
While it is true that in general, our ears do not hear directional sounds
While it is true that in general, our ears do not hear directional sounds
at the low frequencies where subwoofers operate, when installing
a subwoofer within the limited confines of a room, the reflections,
standing waves and absorptions generated within the room will
strongly influence the performance of any subwoofer system. As
a result, the specific location of the subwoofer in the room does
become important to the amount and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will
For example, placing the subwoofer next to a wall generally will
increase the amount of bass in the room; placing it in a corner (

)
generally will maximize amount of bass in the room. However, corner
placement can also increase the destructive effect of standing waves
on bass performance. This effect can vary depending on the listening
position – some listening positions may yield very good results,
while others may have far too much (or too little) bass at certain
frequencies.
In many rooms, placing the subwoofer along the same plane as the
In many rooms, placing the subwoofer along the same plane as the
soundbar (

the subwoofer and that of the left and right speakers. In some rooms,
the best performance could even result from placing the subwoofer
behind the listening position (

We strongly recommend that you experiment with placement before
choosing a final location for your subwoofer. One way you can
determine the best location for the subwoofer is by temporarily
placing it in the listening position and playing music with strong
bass content. Move around to various locations in the room while
the system is playing (putting your ears where the subwoofer would
be placed), and listen until you find the location where the bass
performance is best. Place the subwoofer in that location.

analog:
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.
digital:
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,

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.

suBWOOFer cutOFF cONtrOL
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.

To set the Cutoff control, listen for the smoothness of the bass. If the

setting. If the bass seems too weak at certain frequencies, try a higher
Cutoff control setting.
suBWOOFer PHase sWitcH
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.

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.
