Preparing Your Receiver
Connecting the A and B Speakers
Follow these steps to connect the right speaker to the receiver’s right FRONT
SPEAKERS A terminals.
1. Press the receiver’s FRONT SPEAKERS A R (+) red lever and insert the
ridged or color-coded conductor’s end into the small hole. Pull back the
lever to secure the conductor.
2. Press the receiver’s FRONT SPEAKERS A R ( – ) black lever and insert the
other conductor’s end into the small hole. Pull back the lever to secure the
conductor.
3. Connect the ridged or color-coded conductor’s loose end to the right
speaker’s positive (+) terminal.
4. Connect the remaining loose conductor to the right speaker’s negative (–)
terminal.
Repeat Steps 1 through 4 to connect the left speaker to the receiver’s FRONT
SPEAKERS A L terminals.
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, as shown. 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.
Radio Shack stores sell a variety of suitable subwoofers and amplifiers.
Note: Be sure you connect the
receiver’s right and left positive (+) and
negative (–) terminals to the speaker’s
corresponding right and left positive (+)
and negative (–) terminals.
