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 6, 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 6.

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. 

panel is at least 150 mm or 6" away from the wall to allow  

 
    

you may place wireless subwoofer in the positions as represented in the 
above figure. 

•  Placing it in a corner that is position (1) will maximize the amount of bass

in the room. However, corner placement can also increase the destructive 
effect of the 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 too much (or too little) bass at 
certain frequencies. 

•  Placing the subwoofer along the same plane as the soundbase – position

(2) – can produce the best integration between the sound of the subwoofer 
and the soundbase. in some rooms, the best performance can be resulted 
by placing the subwoofer behind the listening position (3). 

you can experiment with subwoofer placement by temporarily placing the 
subwoofer in the listening position and playing music with strong bass 
content. move it to various locations in the room while the system is playing 
until you determine where the location of the best bass performance occurs. 
Place the subwoofer in that location. 

Manually: First, make certain that the rear panel power switch is 
turned On. Then, short press the JBL Cinema SB350’s Power button either 
on the soundbar or the remote. To put the JBL Cinema SB350 into Standby 
manually, short press the Power button either on the soundbar or the remote 
again.

Auto turn-off: The JBL Cinema SB350 will automatically enter 
into Standby mode if no audio signal is detected at any of its source input 
connections for approximately 10 minutes.

Auto turn-on: The JBL Cinema SB350 has a signal detector that 
automatically turns the unit On when it senses an audio signal on the HDmi

input or paired Bluetooth source (when using HDmi, TV must support HDmi 
aRC). The auto turn-on mode gets activated for analog or optical inputs only 
when the JBL Cinema SB350 detects an audio signal on the input it was on 
before going into automatic Standby mode.

Harman display Surround: This button turns the 
JBL Cinema SB350’s Harman Display Surround processing On/OFF. The 
Surround button indicator on the JBL Cinema SB350 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. 

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 6 for more information.

Turning the subwoofer oN and off 
Once the subwoofer and soundbar have been paired (see Pairing the Units 
for Wireless Operation, below) the subwoofer will turn on when the soundbar 
turns on and will remain on for approximately one minute after the soundbar 
enters the Standby mode, or for approximately 10 minutes after the audio 
signal ceases.

after turning the soundbar and subwoofer on for the first time, you will need 
to “pair” them both so they’ll both operate at the same wireless frequency. 
To pair the units, press the Wireless Pairing switches on both units within 
30 seconds of each other. The units will communicate with each other and 
operate at the same frequency.

Bluetooth button LeD will be flashing blue). if the LeD is not flashing blue, 
press and hold the Bluetooth button until its LeD starts flashing blue.
