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-

TO SUBWOOFER Output. Color-coded binding posts are provided to identify where the Soundolier THP - 7, Soundolier THP - Soundolier SubCenter or other subwoofer should be connected. The red terminal is ( + ); and the black terminal is ( - ). - Page 4 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.

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 ”...

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. - Page 11 ON check the RCA patch cord connections between LINE OUT on the THP-CXB and INPUTS on the power amplifier check the speaker wire connections between the power amplifier and main or satellite speakers...
