Model T70.1 PBM
●
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!
