Connecting Your Subwoofer

The Atlantic Technology System 272 PBM THX Powered Subwoofer is simple to hook up, offering
several connection methods for maximum flexibility. Study the system diagrams starting on page 6.
Once you have found the example which most closely matches your system, hook up your
subwoofer(s) as shown in that diagram.

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!

Low Level Connection

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. Please consult your
processor/receiver manual for further information.
