the jack. Then connect the center channel speaker to the amplifier.
CENTER
Your receiver includes a line-level subwoofer output. Connecting a subwoofer to
your system dramatically extends bass response for incredible richness and
depth. When you listen to surround-sound programs, a subwoofer enhances
your home theater experience by realistically re-creating the rumble of an earth-
quake, the bone-jarring percussion of a cannon, and more. To use the sub-
woofer output, simply connect it to an amplified subwoofer's line-level input or to
an amplifier to which you have connected a subwoofer.
RadioShack stores sell a variety of suitable subwoofers and amplifiers.
