INTRODUCTION
JBL Balboa™SUB10 Powered
Subwoofer
For more than 60 years, JBL®has been providing audio equipment
to concert halls, recording studios and movie theaters around the
world, and has become the hands-down choice of leading recording
artists and sound engineers.
With the JBL Balboa Series, innovative technologies such as
titanium-laminate-dome tweeters, EOS waveguides and high-
performance transducers are available to you. Enjoy!
Unpacking the Subwoofer
If you suspect damage from transit, report it immediately to your
dealer. Keep the shipping carton and packing materials for future use.
PLACEMENT
Since the installation of a subwoofer can be somewhat more
complicated than installing full-range speakers, it is essential
that you read this section very carefully prior to connecting the
subwoofer to your system. Should you have questions relating to
your installation, it is advisable to contact either your dealer or
distributor, or visit www.jbl.com, for advice.
The performance of the subwoofer is directly related to its
placement in the listening room and how you align the subwoofer
with its satellite speakers. Setting the volume of the subwoofer
in relation to the left and right speakers is also of critical importance
because it is essential that the subwoofer integrate smoothly with the
entire system. Setting the subwoofer’s volume level too high will
result in an overpowering, boomy bass. Settingthe volume level too
low will negate the benefits of the subwoofer.
Here are several additional facts on installation that may prove
useful. It is generally believed by most audio authorities that low
frequencies (below 125Hz) are nondirectional and, therefore,
placement of a subwoofer within any listening room is not critical.
While in theory it is true that the larger wavelengths of extremely
low frequencies are basically nondirectional, the fact is that,
when installing a subwoofer within the limited confines of a room,
reflections, standing waves and absorptions generated within the
room will strongly influence the performance of any subwoofer
system. As a result, specific location of the subwoofer becomes
important, and we strongly recommend that you experiment with
placement before choosing a final location.
Placement will depend upon your room and the amount and quality
of bass required (for example, whether or not your room permits
placement of the subwoofer near either satellite). Be sure to leave a
minimum of six inches between the wall and the port on the subwoofer.

Power On
Plug your subwoofer’s AC cord into a wall outlet. Do not use the
outlets on the back of the receiver.
Initially set the Subwoofer-Level Control ¡tothe “min” position.
Turn on your sub by pressing the Power Switch ¶on the rear panel.
Turn on your entire audio system and start a CD or movie soundtrack
at a moderate level.
Auto On/Standby
With the Power Switch ¶in the ON position, the LED §on the rear
panel will remain lit in red or green to indicate the On/Standby mode
of the subwoofer.
RED = STANDBY (no signal detected, amp off)
GREEN = ON (signal detected, amp on)
The subwoofer will automatically enter the Standby mode after
approximately 10 minutes when no signal is detected from your
system. The subwoofer will then power ON instantly when a signal
is detected. During periods of normal use, the Power Switch ¶
can be left on. You may turn off the Power Switch ¶for extended
periods of nonoperation, e.g., when you are away on vacation.
Adjust Level
Turn your Subwoofer-Level Control ¡up to the “5” position
(halfway). If no sound emanates from the subwoofer,check the
AC-line cord and input cables. Are the connectors on the cables
making proper contact? Is the AC plug connected to a “live”
receptacle? Has the Power Switch ¶been pressed to the “On”
position? Once you have confirmed that the subwoofer is active,
proceed by playing a CD, record or cassette. Use a selection that
has ample bass information.
Set the overall volume control of the preamplifier or stereo to a
comfortable level. Adjust the Subwoofer-Level Control ¡until
you obtain a pleasing blend of bass. Bass response should not
overpower the room but rather be adjusted so there is a harmonious
blend across the entire musical range. Many users have a tendency
to set the subwoofer volume too loud, adhering to the belief that a
subwoofer is there to produce lots of bass. This is not entirely true.
Asubwoofer is there to enhance bass, extending the response of
the entire system so the bass can be felt as well as heard. However,
overall balance must be maintained or the music will not sound
natural. An experienced listener will set the volume of the subwoofer
so its impact on bass response is always there but never obtrusive.
Phase Control
The Phase Switch £determines whether the subwoofer speaker’s
piston-like action moves in and out with the main speakers (0˚), or
opposite the main speakers (180˚). Proper phase adjustment depends
on several variables such as room size, subwoofer placement and
listener position. Adjust the phase switch to maximize bass output
atthe listening position.
Crossover Adjustments
The Crossover Adjustment Control ™determines the highest
frequency at which the subwoofer reproduces sounds. If your main
speakers can comfortably reproduce some low-frequency sounds,
set this control to a lower frequency setting, between 50Hz and
100Hz. This will concentrate the subwoofer’sefforts on the ultradeep
bass sounds required by today’s films and music. If you are using
smaller bookshelf speakers that do not extend to the lower bass
frequencies, set the Crossover Adjustment Control to a higher
setting, between 120Hz and 150Hz.
N
NO OT TE E: This control will have no effect if the LFE Input ¢is used. If
you have a Dolby Digital or DTS processor/receiver, the Low-Pass
Frequency is set by the processor/receiver. Consult your owner’s
manual to learn how to view or change this setting.
OPERATION
BALBOA Sub10.OM.qxd 8/2/06 3:22 PM Page 7

The enclosure may be cleaned using a soft cloth to remove
fingerprints or to wipe off dust.
The grille may be gently vacuumed. Stains may be removed with an
aerosol cleaner, following its instructions. Do not use any solvents
on the grille.
All wiring connections should be inspected and cleaned or remade
periodically. The frequency of maintenance depends on the metals
involved in the connections, atmospheric conditions, and other
factors, but once per year is the minimum.
If a problem occurs, make sure that all connections are properly
made and clean. If a problem exists in one loudspeaker, reverse the
connection wires to the left and right system. If the problem remains
in the same speaker, then the fault is with the loud-speaker. If the
problem appears in the opposite speaker, the cause is in another
component or cable. In the event that your subwoofer ever needs
service, contact your local JBL dealer or distributor or www.jbl.com
for a service center near you.
