T70.1 PBM
High Performance Powered Subwoofer
Congratulations on your purchase of an Atlantic Technology T70.1
PBM powered subwoofer. With proper care, your new subwoofer will
provide many years of trouble-free performance.
The T70.1 PBM is capable of delivering very high output levels and
wide dynamic range. When properly placed it will provide smooth inroom bass response down to approximately 25Hz, with a peak SPL of
103dB (1500 cubic foot space).
The built-in proprietary high-current amplifier is conservatively rated
at 125 watts RMS. This amplifier, coupled with a massive 10" longthrow treated cellulose pulp woofer in a sealed enclosure, generates
musically accurate deep bass with a minimum of distortion.
Your Atlantic Technology powered subwoofer will smoothly integrate
with virtually all other brands of loudspeakers on the market as all its
internal electronics have been designed to maintain optimum signal integrity. From the premium
quality amplifier to the clearly marked controls, this is one of the most versatile high performance
subwoofers you can buy. An added benefit is its relatively compact size and straight forward design.
Your Atlantic Technology powered subwoofer has been engineered using the latest technology and
finest components available. It features:
●
A long-throw 10" driver with vented motor structure and 2" high temperature, 4-layer voice coil
This powerful driver has a very stiff treated cellulose pulp cone that acts as an almost perfect
piston throughout its operating range. Its massive magnetic motor assembly and high
temperature component parts deliver high performance and exceptional reliability.
●
A sealed enclosure for low distortion and deep bass output
Sealed enclosure designs are inherently low in distortion and naturally deliver deep, smooth bass
response with a gradual and predictable roll-off below resonance. As with all Atlantic Technology
subwoofers, we have paid inordinate attention to giving you accurate musical bass reproduction
along with terrific special effects.
●
A linear power high current Class A/B amplifier conservatively rated at 125 watts RMS
The T70.1 PBM’s custom-designed discrete amplifier has been precision matched and equalized
to its 10" driver. It exerts accurate and powerful control over the driver for the best performance
possible.
●
A useful in room working frequency range of 25Hz to 150Hz
●
A continuously adjustable 24dB/octave crossover with a range of 60 Hz to 150Hz
This sophisticated crossover’s steep upper end roll-off slope of 24 dB per octave allows for
exceptional integration with most any brand or type of satellite speaker on the market. In
particular, the 24dB/octave design makes the T70.1 PBM ideal for use with compact, bass
restricted satellite speakers.

Important Note: If you are using a surround receiver/processor that includes its own filtered subwoofer
output we recommend that you set the crossover switch on the T70.1 PBM to Bypass.
●
Two line inputs, two line outputs
The outputs allow daisy chaining of multiple subwoofers, or can act as a return path back to the
processor.
●
Two high level inputs, two high level outputs
These let you connect the subwoofer to your amplifier using the amplifier’s speaker outputs. The
speaker outputs may be connected to the left and right front satellite speakers.

A Phase Invert switch (Normal/Invert)
This switch allows precise acoustic matching with speaker systems whose output may be phase
reversed. This switch also allows you to compensate for unusual room acoustics that occur when
a woofer is physically separated from the midrange/high frequency units. Be sure to try the Phase
switch in both positions when you set up the T70.1 PBM. Even if you just change the built-in
crossover settings it’s a good idea to try the Phase switch in both positions, since the crossover
control and the Phase switch acoustically interact with each other.

A rear panel mounted level control

Automatic standby operation
Automatic standby features automatic signal sensing turn on and a 7-12 minute turn-off delay.

Designed and built to meet all CSA and CE safety requirements
Connecting Your Subwoofer
The Atlantic Technology System T70.1 PBM Powered Subwoofer is simple to hook up, offering several
connection methods for maximum flexibility. Study the system diagrams starting on the next page.
Once you have found the example which most closely matches your system, hook up your
subwoofer(s) as shown in that diagram.
Low-Level Connection
If you have purchased the entire System T70, we suggest using the low-level (RCA jack) subwoofer line
out or preamp output if your receiver/processor has one. Simply connect your subwoofer with high
quality shielded cables as shown in the diagrams. Use the diagram that best suits your connection
requirements.
Using the Low-level Output
If desired, you can run a line level signal through the T70.1 PBM and out to another unit. This way
you can add an additional subwoofer with minimal additional wiring. The signal that comes out of the
Output jacks is identical to the input signal.
High-Level Connection
Alternately, you may use the high-level (speaker) inputs. We recommend that you connect your new
T70.1 PBM Powered Subwoofer(s) using high quality wire of 16 gauge or larger. There are many
respected manufacturers in the audio industry that specialize in speaker wire and interconnect cables
suitable for your new system. Please consult your audio/video dealer for more specific information.
High-level Output
If desired, you can run a high level signal into the T70.1 PBM and directly out to the left and right
front speakers. This method is primarily intended for systems without a built-in crossover or a
dedicated subwoofer output. The signal that comes from the High-level Output jacks is identical to the
input signal.
Warning: To prevent risk of electrical shock or damage to your equipment, always unplug all component AC
cords before proceeding with speaker and component connections! The last step in wiring your system should
be plugging in the AC cords!
