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.
OPERATION
Turning the JBL CINEMA BASE ON
and OFF
Manually:
First, make certain that the rear panel power switch is
turned ON. Then, short press the JBL CINEMA BASE Power button either on
the soundbase or the remote. To put the JBL CINEMA BASE into Standby
manually, short press the Power button either on the soundbase or the
remote again.
Auto turn-off:
The JBL CINEMA BASE 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 BASE 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 BASE detects an audio signal on the input it was on
before going into automatic Standby mode.
NOTE:
If the JBL CINEMA BASE is put in standby using the
power button, this will deactivate the auto turn-on feature on
the analog and optical inputs.

To wirelessly stream audio to the JBL CINEMA BASE from a Bluetooth-enabled
device:
1. Confirm that the JBL CINEMA BASE is in the Bluetooth pairing mode (the
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.
2. Place your Bluetooth-streaming device in pairing mode.
Warning Note:
Please be careful while placing/moving
the TV foot. It may scratch/damage the leather casing at the
top of your Cinema Base.
Note:
Maximum TV Stand Size (L x W): 23

(585mm
x 342mm). TV stands are recommended to fit within the
designated area. JBL CINEMA BASE supports TVs with
weights up to 150lbs (68kg).
Placing the Optional Subwoofer
The JBL CINEMA BASE features enhanced bass performance with built-in
dual subwoofers. Should you feel the need to add an optional subwoofer,
this is done by connecting an external subwoofer to the “Sub Out” output on
the rear panel of the soundbase. The performance of an external subwoofer
is directly related to its placement in the listening room and its physical
position relative to the other speakers in the system. Note that our ears do
not typically localize the low frequencies that subwoofers reproduce. Because
the reflections, standing waves and absorptions generated within a room
will strongly influence the performance of any external subwoofer system,
the specific location of the subwoofer in the room becomes important to the
amount and quality of bass that is produced, requiring some experimentation
in positioning.
IMPORTANT:
Make sure that the subwoofer’s rear
panel is at least 150 mm or 6
"
away from the wall to allow for
proper operation.

You may place any external 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).
