Connecting Your Subwoofer
Use the low-level (RCA jack) subwoofer line out of your surround sound receiver/processor. Simply connect your subwoofer with a high quality shielded cable as shown in the diagram on page 7. Please consult your processor/receiver manual for further information.
Warning: To prevent risk of electrical shock or damage to your equipment, always unplug all component AC cords before pro- ceeding with speaker and component connections! The last step in wiring your system should be plugging in the AC cords!
Subwoofer Line Out to Low Level In
Run an RCA cable from your receiver’s Sub Out jack to the L/Mono input jack on the back of the 642e SB (Figure 3).If your receiver/processor has stereo subwoofer outputs,connect these to both the L/Mono and R jacks on the back of the 642e SB (Figure 4).
Using the Low Level Output
If desired, you can run a low level signal through the 642e SB and out to another unit. This way you can add an additional subwoofer with mini- mal additional wiring. The signal that comes out of the output jacks is identical to the input signal.
