THP-CXB Owner’s Manual
Congratulations on your purchase of the Atlas/Soundolier THP - CXB Subwoofer Power Amplifier.
Coupled with any of the Soundolier Passive Subwoofer Speaker Systems, it will give your audio/video
system excellent low frequency output.
Bass frequencies are critical to realistic sound reproductions. After you’ve hooked up the THP-CXB
with a subwoofer speaker system, you will discover just how much “punch” and depth you’ve been miss-
ing. No matter what kind of music you listen to... whether you listen to it loud or soft... you’ll experience
sound that’s richer and fuller. Bass guitar and string bass will have more impact. You’ll be able to FEEL
as well as hear percussion just the way you would at a live performance. If you have a “Home Theater
System” movies will come alive with thunderous sound effects that were never possible without the
THP-CXB Subwoofer Power Amplifier coupled with any Soundolier Passive Subwoofer Speaker.
The THP-CXB is a dedicated subwoofer amplifier with active crossover. It frees your receiver or power
amplifier from the power demands of high-performance subwoofers such as the Soundolier
THP - 1,
Freestanding Subwoofer the Soundolier T/P - 2 In-Floor Subwoofer, and the SubCenter System. To do
this, the 7HP-CXB incorporates a built-in crossover system that can automatically “assign” higher fre-
quencies to the main speakers and lower frequencies to the subwoofer.
The THP-CXB has been designed and tested to insure high performance, durability and longevity. The
THP-CXB can be used with any
4-ohm or 8-ohm subwoofer that requires a separate power amplifier.
This manual is designed to take you step-by-step through the hook-up and operating process. The pro-
cedure is not difficult, but IS slightly different than connecting line level components such as a CD play
er or cassette deck. Reading this manual carefully will insure maximum performance from your
THP-
CXB and subwoofer speaker.

FROM RECEIVER ( speaker-level ) inputs. These spring-terminal, color-coded connections are used to connect the THP-
CXB to your receiver. They are used with one of the hook-up methods described in the next section.
LINE IN & LINE OUT ( line level ) connections. These connections are used ONLY if you have a preamplifier or a receiv-
er/integrated amplifier which has line level outputs that follow the volume control. The LINE IN connections on the THP-
CXB are also used to connect the “s&woofer output” from most A# Surround Sound Receivers.
TO SPEAKERS (speaker level) outputs. If you are using the FROM RECEIVER inputs, you will hook your main speakers to
these spring-terminal, color-coded connections. They are NOT used with the LINE IN / LINE OUT connection method.
Q-OHM / 8-OHM Switch.
This switch should be placed in the setting that matches the specifications of the subwoofer
being used. If you are using the THP-CXB with the Soundolier THP - 1 Freestanding Subwoofer or the Soundolier
THP - 2 In-Floor Subwoofer, configure the jumpers on the subwoofer cabinet for “4-ohm operation”. Consult the THP - 7
or THP - 2 owner’s manual for additional information.
If you are using the THP-CXB with the Soundolier SubCenter,
configure the jumpers on the SubCenter cabinet for “8-ohm operation”.
/VOTE: The THP-CXB is NOT compatible with 2-ohm speaker systems.
TO SUBWOOFER Output. Color-coded binding posts are provided to identify where the Soundolier THP - 7, Soundolier THP - 2,
Soundolier SubCenter or other subwoofer should be connected. The red terminal is ( + ); and the black terminal is ( - ).
WHERE TO PUT THE THP-CXB
The THP-CXf3 is intended to be placed on a shelf in a stereo rack or bookcase along with your other audio/video components.
Make sure that you leave enough room on the top and sides of the unit for adequate ventilation. Also, try to avoid placing the
THP-CXB on top of a high-wattage power amplifier or receiver (over 100 watts per channel), since it can block the ventilation
of the component below and could become overheated.
CONNECTING THE THP-CXB TO A WALL PLUG
The THP-CXB draws a moderately high amount of current. We do not recommend plugging it into a “convenience” outlet
(switched or unswitched) that are often found on the back of receivers and other stereo components. Instead, connect the THP-
CXf3 directly to its own AC outlet. See items 8 and 9 in the Safety Instructions.
Both hook-up methods, “Amplifier Wiring Hook-Up” and “Line Level Hook-up” require speaker wire connections. Here are some
suggestions that will insure proper operation:
PREPARING SPEAKER WIRES
1. Separate the two conductors that comprise each speaker wire and strip off 318” of the insulation from both ends of each
conductor.
2. Twist each set of thin wires into a tightly bunched spiral. If the wire is exceptionally thick ( 12-gauge zipcord or
special speaker interconnect cable), divide the strands into three equal bundles and twist each into a
spiral. For connections between the THP-CXB and the subwoofer, you can also use speaker wire connectors that
attach to the speaker wire, such as spade lugs or banana plugs. Your audio dealer can advise you on this.

ESTABLISHING POLARITY
It is very important that left and right connections be made with the same plus / minus polarity.
lMost speaker wire is polarity coded. This means that each conductor is labeled either ( + ) or ( - ). The positive ( + )
conductor may be a different color or texture than the negative ( - ) conductor. For instance, it may be copper-colored
(instead of silver colored), have a series of fine ridges stamped in it or simply be labeled with little ( + ) marks.
l Most speaker and subwoofer terminals are color coded: Red for positive ( + ) and black for negative ( - ) .
l Any connection that uses speaker wire requires care in maintaining polarity. When connecting speakers or a subwoofer to
speaker terminals, make sure to connect ( + ) wires to ( + ) terminals, and ( - ) wires to ( - ) terminals. For example, if
your speaker wire has one copper-colored conductor and one silvered-colored connector, connect both ends of the copper- q
colored wire ( + ) to red ( + ) terminals. Likewise, connect the wire you have identified as negative ( in this case, the
silver colored wire ) to black terminals.
SPEAKER WIRE TYPE
The choice of speaker wire type is dependent on the type of amplifier, the distance you intend to run the wire and your budget. In
general, you should not use extremely thin wire. If in doubt as to what brand or type of wire to use, consult your audio dealer.
LENGTH OF SPEAKER WIRES
When hooking-up your main /satellite speakers, make the hook-up wires the SAME LENGTH for BOTH speakers, even if one
is much closer to your amplifier than the other one. You may need to loosely coil up part of one channel’s wire behind the ampli-
fier if one speaker is quite close and the other far away from the amplifier or receiver. But it’s worth it. Keeping both wires the
same length will help maintain proper signal balance and imaging. Likewise, when making connections between your receiver
and the THP-CXB’s ’ FROM SPEAKERS ” terminals, make the wire lengths the same.
First, determjne whether the receiver has line level outputs (most don’t). Look on the
back of the unit or consult the owners manual. Line level outputs are often part of a set of
four jacks connected by small ” U ’ shaped connectors and marked
” PRE ” and “MAIN “.
These outputs are also sometimes marked ’ PRE OUT ‘.

Method B-2 - preampliner 8nd power empllfier. All preamplifiers have left and right line level outputs which are con-
trolled by the preamp’s volume control. These are marked; OUT, PRE OU7; or MAIN OUT. See page 8.
Method B-3 - A/V Surround Sound Receiver or outboard decoder. Most multi-channel
” A# Surround Sound
Receivers ’ and separate decoders have a dedicated line level output for subwoofer operation. This output, usually labeled
* Subwoofer Out “, can be directly connected to the LEFT or RIGHT ” Line In ” connections on the THP-CXB. For
increased performance, use an RCA
” Y ” adapter ( single female / dual male ) to apply the ’ Subwoofer Out ” to both
LEFT and RIGHT II Line Inputs ’ on the THP-CXB . See page 9.
NOTE: Some surround processors have their own internal crossovers assigned to the ’ SUBWOOFER OUTPUT ” connection. Consult the
Surround Sound Processors owner’s manual to determine if the unit has an internal crossover. Combining the THP-CXB ‘s crossover with the
crossover in the surround sound processor may result in low output volume and’ increased noise. If this condition arises, use; Method A-l
”
Amplifier wiring For Mosf Receivers ‘via the main speaker terminal outputs of the A# receiver or processor.
USING TWO SUBWOOFERS If using two a-ohm subwoofers wired together in parallel, set the 4-OHM / a-OHM switch on the back of the
TNP-CXB to the 4-ohm position. Do not attempt to use TWO subwoofers that create less than a combined 4 ohms load to the THP-CXB.
,

1. IMPORTANT: Make sure that ALL stereo components including the THP-CXf3 are turned OFF before proceeding.
2. Following the directions on “Preparing Speaker Wires”, strip and twist TWO lengths of speaker wire that will reach between the receiv-
er’s speaker terminals and the THP-CXB. Make these two lengths of wire only as long as is necessary to run between the two
components.
3. Connect one speaker wire to the RIGHT ( + ) and ( - ) speaker terminals of the receiver or integrated amplifier. Then connect the
other end of this speaker wire to the RIGHT ( + ) and ( - ) FROM AMPLIFIER terminals on the back of the THP-CXB. Use the tips
on determining speaker wire polarity to make sure that ( + ) is connected to ( + ) and ( - ) is connected to ( - ).
4. Connect the other speaker wire to the LEFT ( + ) and ( - ) speaker terminals of the receiver or integrated amplifier. Then connect
the other end of this speaker wire to the LEFT ( + ) and ( - ) FROM AMPLIFIER terminals on the back of the THP-CXB. As in step
3, double check polarity.
5. Connect the main left and right channel speakers to the THP-CXB “TO SPEAKERS” terminals.
6. Connect the Soundolier or other subwoofer to the round red and black “TO SUBWOOFER” terminals on the back of the THP-CXB.
Make sure that polarity is correct, using the BLACK binding post for the ( - ) connection and the RED binding post for the ( + ) con-
nection.
7. IMPORTANT: Consult the owner’s manual that
came with the subwoofer to determine if it is rated
at 4 ohms or 8 ohms. Then set the THP-CXBS
“4 OHM / 8 OHM” switch accordingly. If you are
using two subwoofers, refer to the section titled;

Line Level Hook-Up
with Preamplifier and
Power Amplifier

In most cases, the main output of the decoder/processor will be connected to the THP-CXB’s
“LINE IN “connection as shown
in the drawing below. Some decoders have a dedicated line level output for subwoofer operation. This output, usually labeled
” Subwoofer Out “, can be directly connected to the LEFT or RIGHT “Line In” connections on the
THP-CXB . For increased
performance, use an RCA “Y ‘adapter ( single female / dual male ) to apply the ” Subwoofer Out “to both LER and RIGHT
“Line Inputs” on the THP-CXB .
NOTE: Some surround sound processors have their own internal crossovers associated with the dedicated “SUBWOOFER
OUTPUT” connection. Combining the THP-CXf3 ‘s crossover with the crossover in the surround sound processor may result in
low output volume and increased noise. If the surround sound processor is not configured as shown in this drawing, use;
Method A-l “Amplifier Wiring For Most Receivers “via the main speaker terminal outputs of your receiver or integrated ampli-
fier.
LINE LEVEL CONNECTIONS WITH
A SURROUND SOUND RECEIVER
Many “5-channel Surround Sound
Receivers” and some hybrid AN pre-
amplifiers, may also have a “SUB-
WOOFER OUT” connection. As
noted above, combining this output
with the THP-CXB ‘s crossover may
result in low output volume and
increased noise. Do not attempt to
connect the “SUBWOOFER OUT”
output to the THP-CXB unless you
are certain that is not connected to an
internal crossover.

The THP-CXB’s controls are pure simplicity; An ON / OFF switch, an LED indicator, and a big volume control.
1. MAIN POWER SWITCH.
This rocker switch turns the THP-CXB on and off. We recommend that you turn the THP-CXB
on LAST, in the sequence of the receiver / integrated amp / preamp, CD player, cassette deck, etc. Some components send
out loud, low-frequency THUMP S when they are turned on. These thumps are not only startling and annoying, but could
also cause damage to the subwoofer if the volume control is cranked up high.
2. POWER ON INDICATOR LIGHT. When the small LED light is lit, the THP-CXB is on.
3. VOLUME CONTROL.
Rotating this knob clockwise increases the output level of the subwoofer. To start out, make sure the
VOLUME is turned all the way down ( fully counter-clockwise ). Later, after some initial listening tests, you can adjust the
volume to your own tastes. However, care should be taken not to over-drive the subwoofer to the point of audible distortion.
It’s now time to introduce the THP-CXB and subwoofer combination into the listening environment.
1. Double-check all connections.
2. Make sure that the volume controls on both the THP-CXf3 and the receiver / integrated amplifier / preamp are turned all the
way down ( counter-clockwise ).
3. Turn on the stereo system. Then turn on the THP-CXB. Confirm that the THP-CXB ‘s indicator light is glowing. If it isn’t,
check the power connections between the THP-CXB and the wall socket.
4. Play a musical selection that you are familiar with. Pick a song that has regular low bass beats. Advance the receiver /
integrated amp / preamp’s volume control up to a normal listening level. If you don’t hear sound through your main speak-
ers, turn off the system and check all connections. Also consult the troubleshooting tips in section G.
5. If sound is indeed coming out of the main speakers, turn the THP-CXf3 ‘s volume control clockwise until you hear noticeable
additional bass. If you don’t hear additional bass by the time you have advanced the THP-CXB ‘s volurrre control halfway,
turn off the system and check all connections. Also consult the troubleshooting tips in section G.
6
Adjust the THP-CXB’s volume control until you are satisfied with the amount of additional bass. You may want to try
several different albums, tapes or compact discs while determining how high to adjust the THP-CXB volume control. The
amount of bass varies for different types of music.
7. After you are satisfied with the output of your subwoofer, you can make all the volume settings through the main stereo’s
systems volume control. The only time you might want to re-adjust the THP-CXB ‘s volume is when you encounter a musi-
cal selection that has extreme low or high bass levels.
8. A tip during normal operation: turn the THP-CXB off first, before your other components.
SUBWOOFER PLACEMENT
The Owner’s Manual that comes with Soundolier Subwoofers covers the advantages and disadvantages of various subwoofer
placement options. We encourage you to experiment with both main speaker placement and subwoofer placement for the best
performance in your listening environment.
MAINTENANCE
Normal dust accumulations can be removed with a vacuum brush attachment or duster. To remove fingerprints and other real-
world substances that seem to mysteriously appear on stereo components, use a lightly-dampened, soft cloth moistened in mild
soap and water.

Before considering service for the THP-CXB, please review these ttvubleshooting suggestions:
No sound. Power light is not lit.
1.
Is the THP-CXB plugged into a live AC wall socket ?
2. Is the power switch ON ?
3. Has the THP-CXB overheated and shut off temporarily ?
No sound from either set of speakers.
1. Are the other audio/video components turned ON ?
2. Is the receiver or preamp set to the appropriate input and is that sound source playing ?
.3. Do you have an unconnected tape monitor selected ?
4. Is the THP-CX5 correctly connected to the receiver, preamplifier or integrated amplifier ?
Sound comes from the main speakers but not the Subwoofer.
1. Is the THP-CXf3 ‘s VOLUME control turned up.
2. Is the subwoofer correctly connected to the round binding posts on the THP-CXB ?
3. Check the speaker connections for small strands of wire touching both terminals.
