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 metal feet .

•  Set the soundbar’s EQ switch in the “Table” position. See 

Soundbar 

Rear-Panel Controls and Connections,

 on page 2.

WALL-MOUNTING THE SOUNDBAR

If your TV is attached to a wall, you can use the included wall-mount 

bracket 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.  Hold the bracket against the wall as a template and mark the 

locations of the soundbar wall-mount bracket holes on the wall. The 

three holes should be evenly spaced 7-1/16" (18cm) apart, and the 

bracket slots are designed to accept 4mm screws. Make sure that 

the holes are at the same height. See the illustration below.

7-1/16" (18cm) Apart

3.  Making sure that the bracket’s flat side is against the wall, attach 

the wall-mount bracket 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 7.3 lb (3.3kg). Be sure to 

use hardware that can support this weight.

4.  After reading the 

Connections

 section on page 5, connect all cables 

to the soundbar.

IMPORTANT: Do NOT plug the soundbar’s power cord into an AC 

outlet at this time.

•  Set the soundbar’s EQ switch in the “Wall” position, and set the 

soundbar’s Power switch in the “On” position. See 

Soundbar Rear-

Panel Controls and Connections,

 on page 2.

5.  Attach the soundbar to the bracket by sliding the bracket’s upper 

tabs into the slots on the back of the soundbar. The soundbar’s slots 

allow you to adjust the soundbar’s angle on the wall to ensure that it 

is level.

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 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 increase 

the amount of bass in the room; placing it in a corner (1) 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 

soundbar (2) can produce the best integration between the sound 

of the subwoofer and that of the soundbar. In some rooms, the best 

performance could even result from placing the subwoofer behind the 

listening position (3).

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.
