JENSEN JP10SW Subwoofer User Manual

Important Safety Precautions
Attention:
Please read these instructions thoroughly before attempting to
operate your JENSEN Subwoofer. Be sure to save this manual
for future reference. Also save your bill of sale, as it may be
required for warranty service.
Caution:
Please ensure that the correct plug is used on your AC outlet.
Cleaning - Unplug the JENSEN Subwoofer from the wall outlet before cleaning. Do not use liquid cleaners or aerosol
cleaners. Use a damp cloth for cleaning.
Attachments - Do not use attachments not recommended by
JENSEN, as they may cause hazards.
Water and Moisture - Do not use the JENSEN Subwoofer
near water - for example, near a bath tub, wash bowl, kitchen
sink, or laundry tub; in a wet basement, near a swimming pool,
or similar locations.
Ventilation - Slots and openings in the JENSEN Subwoofer
are provided for ventilation, to ensure reliable operation and to
protect it from overheating. These openings must not be
blocked or covered. The openings should never be blocked by
placing the product on a bed, sofa, rug or other similar surface.
The JENSEN subwoofer should not be placed in a built-in
installation, such as a bookcase or rack, unless proper ventilation is provided or JENSEN’s instructions have been followed.
Power Sources - The JENSEN Subwoofer should be operated only from the type of power source indicated on the marking label. If you are not sure of power supply to your home,
consult your JENSEN dealer or local power company.
Grounding and Polarization - The JENSEN Subwoofer may
be equipped with a polarized alternating-current line plug (a
plug having one blade wider than the other). This plug will fit
into the outlet only one way. This is a safety feature. If you are
unable to insert the plug fully into the outlet, try reversing the
plug. If the plug is still unable to fit, contact your electrician to
replace your obsolete outlet.
Power-cord Protection - Power-supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention
to cords at plugs, convenience receptacles and the point
where they exit from the Subwoofer.
Overloading - Do not overload wall outlets, extension cords,
or integral convenience receptacles, as this can result in risk of
fire or electric shock.
Object and Liquid entry - Never push objects of any kind into
this product through openings as they may touch dangerous
voltage points or short-out parts that could result in a fire or
electric shock. Never spill liquid of any kind on the JENSEN
Subwoofer.
Servicing - Do not attempt to service the JENSEN
Subwoofer yourself. Opening or removing covers may expose
you to dangerous voltage or other hazards. Refer all servicing
to qualified JENSEN service personnel.
Damage requiring service - Unplug the JENSEN Subwoofer
from the wall outlet and refer servicing to qualified personnel
under the following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the
product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally by following
the operating instructions. Adjust only those controls
that are covered by the operating instructions. An
improper adjustment may result in damage requiring
extensive work by a qualified technician to restore the
JENSEN Subwoofer to its normal operation.
e. If the JENSEN Subwoofer has been dropped or
damaged in any way.
f. If the product exhibits a distinct change in performance.
Replacement parts - When replacement parts are required,
be sure the service technician has used replacement parts
specified by JENSEN, or those having the same characteristics as the original parts. Unauthorized substitutions may result
in fire, electric shock or other hazards.
Safety check - Upon completion of any service or repairs to
this product, ask the service technician to perform safety
checks to determine that the product is in proper operating
condition.
Heat - The JENSEN Subwoofer should be situated away from
heat sources such as radiators, heat registers, stoves, or other
products (including amplifiers) that produce heat.
Lightning - For added protection for the JENSEN Subwoofer
during a lighting storm, or when left unattended and unused for
long periods of time, unplug from the wall outlet and
disconnect the antenna or cable system. This will prevent
damage to the JENSEN Subwoofer during lighting strikes and
power-line surges.

Introduction
Check your system carefully. If it has been damaged in transit, report the damage immediately by calling your JENSEN
dealer and/or the trucking firm that delivered it. Observe all warnings and cautions.
Warning
To prevent fire or shock hazard,
DO NOT EXPOSE this subwoofer system to rain or excessive moisture.
We recommend that you not
operate your speakers or subwoofer with the bass, treble and
loudness controls set to full
boost. This will place undue
strain on the electronics and
speakers and could damage
them.
The volume control setting on
your Receiver is not a specific
indication of the overall loudness
level of the speakers. The only
important consideration is the
loudness level at which the system can be played, regardless of
where the volume control is set.
Whenever changing cables,
pulling plugs, etc., ALWAYS
TURN OFF ALL EQUIPMENT
including the Subwoofer. This
prevents transients from entering
the speakers and prevents electrical energy from reaching you.
Keep all connections out of the
reach of children.
To avoid electrical shock, DO
NOT OPEN THE SUBWOOFER!
There are no user-serviceable
parts inside.

Your JENSEN Subwoofer delivers powerful, deep bass sound
output for a natural, life-like sonic experience. Please follow the
directions in this manual to achieve the best performance from
your system.
The hook-up and operation of the Subwoofer is the same for a
Home Theater surround sound system or a stereo music
system. The Subwoofer has its own built-in amplifier, so it
works with any sound system. The Subwoofer’s own crossover
network sends bass-only signals to the Subwoofer’s built-in
amplifier. This lets the Subwoofer add extra bass to the output
from your other speakers.
For simplicity, we call your Home Theater system’s or music
system’s main speakers the Front speakers. We call your AV
receiver, stereo receiver, or integrated amplifier the Receiver.
Placement
Your JENSEN Subwoofer must sit on the floor, preferably in a
corner, to work properly. The floor and corner are actually a
part of the Subwoofer’s design.
Place your Subwoofer in the corner nearest your system’s
electronic components to keep wire or cable runs short.

Power Cord – Plug the power cord into an
AC wall outlet or other AC outlet capable of
supplying at least 200 Watts.
Power Switch – Turns the AC supply
completely OFF or sets the Subwoofer to
AUTO ON operation. In AUTO ON, the
Subwoofer is in standby mode until it detects
an audio signal input, then the Subwoofer
turns on automatically. A few minutes after
audio input signals cease, the Subwoofer
automatically returns to standby mode.
Power Indicator LED – This LED is unlit
when the AC power switch is OFF. It glows
RED when the subwoofer is in standby mode
and GREEN when the subwoofer is on.
FUSE 250V 2A – This fuse protects against internal and
external faults. If the POWER switch is ON and the power indicator LED is unlit, unplug the power cord from the AC outlet
and check the fuse by unscrewing the center piece from the
holder. IMPORTANT- If the fuse is blown, replace it only with a
fuse of the same type and current rating.
L, R SPEAKER-IN Terminals – See Connection Option
1. These terminals are for making connections using speaker
wire. If you use this option, do not us Option 2.
L I N E IN Jack – See Connection Option 2. This jack is for
input connection using an audio cable. If you use this option,
do not use Option 1.
LOW PASS FREQUENCY Control – Adjusts the upper
frequency limit for audio signals going to the subwoofer amplifier. This control helps you adjust the system tonal balance.
the Subwoofer in parallel with the Front speakers easier, the
speaker wire connecting the Receiver to the Subwoofer can be
smaller (higher gauge number), since the Subwoofer does not
draw large amounts of power through these wires.

(plain or silver)
Polarity All speakers in a system must be connected with
the same polarity. Speaker wire is marked for polarity so that
you can identify which wire in the pair is which. Polarity is
shown by a color stripe on the insulation, by ridges molded into
the insulation, or by the colors of the wires – one copper and
one silver. Strip the insulation from speaker wire ends to reveal
the bare conductors before connecting to Receiver, Subwoofer
or Speaker terminals.
IMPORTANT – Always connect the red (+) terminal on the
Receiver to the red (+) terminal on the Subwoofer, and the
black (-) terminal on the Receiver to the black (-) terminal on
the Subwoofer. The same is true for hooking the Receiver
outputs to the Front speakers: red (+) to red (+), and black (-)
to black (-). Important: Use Option1 or Option 2, not both.

Option 1
Connection with speaker wire
Connect speaker wires from the Receiver’s front left and right
speaker outputs to the Subwoofer’s Speaker Level-In connections. Connect left channel to left input and right channel to
right input. You have the option of connecting your main
speakers to the speaker B outputs on your Receiver, if it is so
equipped, or you also have the option of connecting your main
speakers using the connections on the Subwoofer. This will
pass the audio signal to your main speakers, except the low
bass which will be produced by your Subwoofer. To use this
connection option, connect your main speakers to the right and
left outputs on the Subwoofer (see illustration 1). Be sure you
take care to maintain proper signal polarity, red to red and
black to black.

Subwoofer initial control settings
• Set the LOW PASS FREQUENCY Control to its center
position
• Set the LEVEL Control fully counterclockwise to MIN. You’ll
reset this control after you make other adjustments.
Adjusting the Subwoofer controls
Adjusting the Subwoofer controls
Limited Warranty
• Play a program on your system. Use a Dolby® Digital or Dolby® Prologic signal, or a music CD. Adjust the Receiver’s volume control for a
comfortable sound level from the system speakers.
• Increase the Subwoofer’s LEVEL Control setting clockwise, so that you
hear the deep bass. Adjust the control for a natural, musical balance
that has plenty of deep bass sound when it’s actually present in the
music.
• Listen carefully to bass voices and, if needed, adjust the LOW PASS
FREQUENCY Control so that they sound natural. Setting the frequency too high will make deep voices soundly excessivley “chesty” or
resonant and will give the upper bass in music a “one-note” quality.
Setting the frequency too low will make deep voices sound “thin” and
will give the music a lack of “warmth.”
• Make fine adjustments until the program has satisfying and natural
sound quality on both bass voices and music.
This warranty remains in effect for five years from date of purchase for
speaker components, one year on subwoofer amplifiers and electronic
components.
Troubleshooting
Subwoofer POWER Indicator LED does not light
• Check the AC outlet the Subwoofer is plugged into to be sure that it is
live. You can use a tester or plug in a lamp to check it.
• If the AC outlet is live, either the power cord or Subwoofer has a problem. Unplug the power cord from the AC outlet and check the fuse by
unscrewing the center piece from the holder. If it is blown, replace the
fuse only with a fuse of the same type and rating. If this doesn’t help,
take the Subwoofer to your dealer for service — THERE ARE NO
USER-SERVICEABLE PARTS INSIDE.
No sound from the Front speakers
• Be sure the Receiver and Subwoofer POWER switches are in the ON
positions.
• Check the Receiver’s Volume Control setting — if it is all the way
down, there won’t be any sound.
• Check that the Receiver’s Input Selector is set to an active source of
audio signals and that a Tape Monitor Loop is not engaged.
• Be sure that the Receiver’s Speaker Selector switch is turned on to the
terminals [A or B, 1 or 2] that you have your Front speakers connected
to. If the Receiver has a headphone jack, you can use headphones to
check the Receiver for output.
• Check the wires and connections from the Receiver’s Front Speaker
Output terminals to the Subwoofer’s SPEAKER-IN terminals.
• Try removing the Subwoofer from the system, leaving your Front
speakers connected to the Receiver. If there still is no sound, take the
Receiver to your dealer for service.
No sound from the Subwoofer
• First, be sure there is sound from the Front speakers and that the
Receiver is working correctly as outlined above.
• Check the Subwoofer’s LEVEL control. If it is all the way counterclockwise, there may be no sound.
• The Subwoofer only reproduces deep bass sound. If the program has
no deep bass, the Subwoofer will not make any sound. Play a program
with plenty of bass, such as jazz or rock music, or an action movie.
• If everything else checks OK, take the Subwoofer to your dealer for
service - THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
