Technicolor - Thomson Advent User Manual

Important Safety Precautions

Attention:

Please read these instructions thoroughly before attempting to
operate your Advent 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 Advent 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
Advent, as they may cause hazards.

Water and Moisture - Do not use the Advent 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.

Accessories - Do not place the Advent Subwoofer on an
unstable cart, stand, tripod, bracket or table. The product may
fall, causing serious injury to a child or adult, and serious
damage to the product. Use only with cart, stand, tripod,
bracket, or table recommended by Advent, or sold with the
Advent Subwoofer. Any mounting of the speakers should
follow Advent’s instructions and should use a mounting
accessory recommended by Advent.

Ventilation - Slots and openings in the Advent 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
Advent subwoofer should not be placed in a built-in
installation, such as a bookcase or rack, unless proper ventila­tion is provided or Advent’s instructions have been followed.

Power Sources - The Advent 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 Advent dealer or local power company.

Grounding and Polarization - The Advent 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.

Lightning - For added protection for the Advent 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 Advent Subwoofer during lighting strikes and
power-line surges.

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 Advent
Subwoofer.

Servicing

- Do not attempt to service the Advent Subwoofer

yourself. Opening or removing covers may expose you to
dangerous voltage or other hazards. Refer all servicing to
qualified Advent service personnel.

Damage requiring service - Unplug the Advent 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
Advent Subwoofer to its normal operation.

e. If the Advent 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 Advent, 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 Advent Subwoofer should be situated away from
heat sources such as radiators, heat registers, stoves, or other
products (including amplifiers) that produce heat.

Introduction

Check your system carefully. If it has been damaged in transit, report
the damage immediately by calling your

Advent 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.

RISK OF ELECTRICAL SHOCK

DO NOT OPEN

CAUTION: T O RE DUCE THE RISK OF ELECTRIC SHOCK, DO NOT

REMOVE THE COVER. NO USER SERVICEABLE PARTS INSIDE.

REFER TO QUALIFIED SERVICE PERSONNEL.

Your Advent 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 Advent 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.

Controls & Connections

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 and OUT Terminals -See Connection Option 1­These terminals are for making connections using speaker wire. If
you use this option, do not use Option 2.
LINE IN Jack – See Connection Option 2
This jack is for input connection using audio cables. If you use this
option, do not use Option 1.
LOW PASS FREQUENCY Control – Adjust the upper frequency
limit for audio signals going to the Subwooofer amplifier. This control
helps you adjust the system tonal balance.
LEVEL Control – Balances the loudness of the Subwoofer relative
to the Front speakers and compensates for room effects on the
Subwoofer’s output.

Connecting your Subwoofer

IMPORTANT – When you make connections, make sure that the
power switches of all components, including the Subwoofer, are
OFF.

Speaker wire Typical speaker wire has a pair of separate conduc­tors with insulating jackets that are molded together. We recom­mend that you use 16-gauge speaker wire for hooking your
Receiver to your Front speakers. To make connections to 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.

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 Option 1 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. 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 for Option 1). Be sure you take care to maintain proper
signal polarity, red to red and black to black.

Option 2 – Connection with an audio cable

This connection uses a low level mono sub signal. This is usually
found on Receivers equipped with Dolby

®

Digital decoding. Locate
the Subwoofer output on the back of your receiver. Using a
standard RCA cable connect the Subwoofer output on the back of
your Receiver to the Line-In on the back of the Subwoofer.

Subwoofer Adjustment & Use

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

• 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 sound excessively “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 music a lack of “warmth.”

• Adjust the Phase Control for maximum bass response. The phase
control can help to align the bass of the Subwoofer with the bass
response of other speakers in the system. Listen to a piece of music
with the Phase Control in one setting. Change the setting on the
switch and listen for an increase or decrease in the bass response.
One setting should produce better bass response. If there is no
change, then your subwoofer and speakers are aligned properly in
either position

.

• Make fine adjustments until the program has satisfying and natural
sound quality on both bass voices and music

.

Troubleshooting

Subwoofer POWER Indicator LED does not light

• Check that the Subwoofer’s POWER switch is in the AUTO ON
position.

• If the POWER Switch is in the AUTO ON position, 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.

• Try removing the Subwoofer from the system, leaving your Front
speaker 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.
