Study the system diagrams starting on page 8. 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 For best performance, we suggest using the low-level (RCA style jacks) subwoofer line out or preamp outputs if your receiver/amplifier has them. Simply connect your subwoofer with high quality shielded cables as shown in the diagrams. High-Level Connection Alternately, you may use the high-level (speaker) inputs. Make sure to match the type and gauge speaker wire used to connect your main speakers. We recommend that you connect your subwoofer using high quality wire of 16 gauge or larger for lengths up to 25 feet. There are many manufacturers who specialize in speaker wire and interconnects suitable for your new system. We recommend that you consult your local audio/video specialist for more specific information. 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. You can connect your subwoofer by using spade lugs or "banana" connectors, or by removing 1/2" of insulation from each wire end, twisting the strands of wire together, placing the wire through one of the post holes and screwing down the nut tightly. Be certain that no stray wire strands are touching across the two terminals as this might damage your amplifier when you turn it on. It is important to observe polarity while making speaker connections: red (+) terminals on the amplifier to red (+) on the speaker, black (-) on the amplifier to black (-) on the speaker. Look carefully at the wires you are using and note that one of the wires in each pair is marked by either a different color, printing, ridges, or a thread intertwined with the wire strands. By convention, the marked wire is connected to the red (+) terminal.

If your receiver/ amplifier uses jumper links between the Pre-out and Main In, then you must remove them and use option 1 or 2. If your receiver/ amplifier uses a switch instead of connectors, then use option 3.

[. . . ] Listen to a monoraul musical source with strong bass content. (For example, you can use the mono switch on an FM tuner or preamp, or use a Y-connector on the outputs of one of your source components to get a mono signal. ) Experiment with the position of the phase switch to get the most extended bass. It should be obvious which is the correct setting. A Word About Center Channel Modes Many surround processors and surround receivers feature a "wide" and "normal" mode for the center channel speaker. Atlantic Technology recommends that the center channel be operated in the "normal" mode when using a powered subwoofer. [. . . ]
