Subwoofer Placement; Placing The Jbl Cinema Sb250 - JBL CINEMA SB250 Owner's Manual

JBL CINEMA SB250
Harman Display Surround: This button turns the JBL
CINEMA SB250's Harman Display Surround processing ON/OFF. The Surround
button indicator on the JBL CINEMA SB250 turns amber when Surround is
active, and turns white when Stereo mode is active. The HARMAN Display
Surround setting will produce a complete surround-sound experience for
anyone sitting in front of and several feet away from the soundbar. Although it
is particularly effective when watching movies, you can also try the HARMAN
Display Surround setting for music.
Stereo: Use this button to switch your system into stereo mode.
Harman Volume: The Harman Volume button on the remote
control activates Harman Volume. Harman Volume helps you keep your sound
levels consistent and reduces extreme volume transitions. These types of
transitions are typically experienced with television commercial interruption or
movie transitions between quiet dialogue and loud sound effects.

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. Refer EQ switch on
page 4 for more information.

Wall-mounting the soundbar
Note: For wall mounting, we recommend removing the feet of the soundbar
by simply unscrewing and storing them for future use.
If your TV is attached to a wall, you can use the included wall-mount bracket to
mount the soundbar on the wall.
1. Determine the location for the soundbar on the wall.
2. Hold the bracket against the wall as a template and mark the locations of
the 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 above. Mark three bracket hole locations: 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 4, connect all cables to the
soundbar.
• 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 4.
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. Insert tabs
on bracket into grooves in soundbar.

Subwoofer placement

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, remember that – 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 subwoofer system's overall performance. As a result, the specific
location of the subwoofer in the room becomes important to the amount and
quality of bass that is produced.
