JBL continually striv es to update and improve existi ng pr oduc ts, as well as create new ones. The
specifications and details in this and related JB L publications are therefore subject to c hange without notic e.

* The Peak Dynamic Power is measured by recording the highest center-to-peak voltage measured across the output of
a resistive load equal to mi nimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.

SUBWOOFER CONNECTIONS

Choose the Subwoofer Connection
That Is Most Suitable for Your
Receiver/Processor

If you have a Dolby®Digital or DTS®receiver/processor with a
low-frequency-effects (LFE) or subwoofer output:

If your receiver/processor does not contain a Dolby Digital or DTS
processor but has a subwoofer output:

NOTE: Some receivers have one subwoofer output.
In that case, it is recommended that you use a Y connector
(not included) to maximize performance.

BALBOA series SUB10

OPERATION

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

Turn on your sub by pressing the Power Switch

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
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
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.
A subwoofer 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
at the 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’s efforts 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.

E

NNOOTTE

: 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.

BALBOA SUB10 Test Set Up and Procedure

SYSTEM AURAL SWEEP TEST
Equipment needed:

• Function /si g nal ge nerator/sw ee p generator

• Integrated Amplifier

• Multimeter

• Speaker cables

General Unit Function (UUT = Unit Under Test)

Switches/knobs on the amplifier faceplate:

Low Pass Freq uency Adjus t ful l CW (150Hz)
Phase switc h – ei th er posi tio n

1. From the signal generator, Connect both right and left line level inputs (RCA) – not the LFE jack - to signal
generator and UUT. Use Y-cable if necessary from mono source.

2. On the amplifier, turn the LEVEL cont rol full Counterclockwise (Min).

3. Turn on generator, adj ust to 100mV, 50 Hz.

4. Plug in UUT; turn the power switch ON. Turn LEVEL control full Clo ckwise (Max).

5. LED should now be Green; immediate bass response should be heard and felt from rear port tube opening.

6. Turn off generator, turn LEVEL control fully Counterclockwise (Min), disconnect RCA cable.

Sweep Function

1. Follow steps 1-6 above, using a sweep generator as a signal source.

2. Sweep generator fr om 20H z t o 1kH z. Li s t en to th e cabinet and driv ers for any rattles, click s, buzzes or
any other noi s es . If any unusual noises are hear d, remove woofer and test.

Driver Function (Woofer)

1. Remove woofer from cabinet; detach + and - wir e clips .

2. Check DC resistance of woofer; i t should be 3.3 ohms ±10%.

3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated
amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.

4. Sweep generator from 20Hz to 1kHz . Li sten to driver for an y ru bbing, buzzing , or other un usual nois es.
