SB350. The system will appear as “Cinema SB350” in the list of Bluetooth 
available devices. When the JBL Cinema SB350’s Bluetooth button LeD 
illuminates constantly, it is paired with your device and you can stream 
audio via Bluetooth from the device to the JBL Cinema SB350.

To listen to audio from the Bluetooth device, press the Bluetooth source button 
on the JBL Cinema SB350 or remote to activate the source. if the JBL Cinema 
SB350 is in Standby mode, you can automatically wake up the system by 
starting to stream an audio Bluetooth signal to the JBL Cinema SB350 as long 
as your device has already been paired with the JBL Cinema SB350.  
To disconnect the Bluetooth device, press and hold the JBL Cinema SB350’s 
Bluetooth button until the LeD begins flashing.

NoTE: 
•  You can manually switch sources to the paired Bluetooth device by

pressing the JBL Cinema SB350’s Bluetooth button.

•  If you switch the JBL CINEMA SB350 to a different source while a paired

Bluetooth device is streaming to the system, the JBL Cinema SB350 will 
send a STOP command and the Bluetooth device will stop streaming.

•  While pairing the Bluetooth device for the first time, it may reset the volume

level to maximum.

Adjusting the System Volume
For the best sound, we recommend turning your TV’s built-in speakers off. 
Consult your TV’s owner’s manual to find out how to do this. if there is no way 
to turn your TV’s speakers off, you can adjust the TV’s volume so that your 
JBL Cinema SB350 system will always supply most of the sound:

1. Using the volume buttons on your TV, turn its volume all the way down.
2. Use the JBL Cinema SB350’s Volume Up/Down buttons to set the sound 
to a comfortable listening level. This way, your JBL Cinema SB350 system 
should always be louder than your TV speakers.

Surround Mode Button 
Press the soundbar’s or remote’s Surround mode indicator to switch the 
sound between normal stereo and surround sound providing 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 take advantage of the Surround setting for adding to your music-
listening experience.

respond to Your TV remote  
you can program the JBL Cinema SB350 to make it respond to your  
TV remote’s power, mute, volume up and volume down commands.  
This programming lets you control power and volume functions of your  
JBL Cinema SB350 soundbar with your TV remote. Before beginning  
to program the JBL Cinema SB350, have your TV remote in hand.  
We recommend sitting down in front of the soundbar.  

if your JBL Cinema SB350 system does not perform the way you think it should, check whether the problem is covered in this section before contacting your 
dealer or a JBL representative.

the remote control.

of the subwoofer). if the LeD is flashing blue, then restart the pairing process.

•  Move the subwoofer closer to the soundbar. The maximum wireless operation

distance is 50 feet (15.3 m).

at more than 50 percent of maximum volume and the power is turned off, the 

volume of the soundbar is automatically reset to 50 percent of the maximum 

volume when the system is turned On.
