Repeat this entire process to connect a second pair of speakers to the FRONT SPEAKERS B terminals.

Connecting Surround-Sound Speakers

You can connect a pair of speakers to the receiver’s REAR SPEAKERS terminals for surround-sound programs. Follow the steps in “Connecting the A and B Speakers.”

Connecting the Center Speaker

The center speaker gives additional ambience to surround sound. Connect the center speaker to the CENTER SPEAKER terminals. Follow the steps in “Con- necting the A and B Speakers.”

Connecting Center Channel and Subwoofer Amplifiers

To increase the center channel’s output power, you can connect an amplifier to the CENTER jack. Then connect the center channel speaker to the amplifier.

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 recreating the rumble of an earth- quake, the bone-jarring percussion of a cannon, and more.

To use this 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.
