Connecting Your Speakers —Continued
Speaker Configuration
For 7.1-channel surround-sound playback, you need
seven speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers you have.
* If you’re using only one surround back speaker, connect it to the
SURR BACK L terminals.
No matter how many speakers you use, a powered sub-
woofer is recommended for a powerful and solid bass.
To get the best from your surround-sound system, you
must set the speaker settings. You can do this automati-
cally (see page 42) or manually (see page 74).
Speaker Connection Precautions
Read the following before connecting your speakers:
• You can connect speakers with an impedance of
between 8 and 16 ohms. If you use speakers with a
lower impedance, and use the amplifier at high volume
levels for a long period of time, the built-in amp pro-
tection circuit may be activated.
• Disconnect the power cord from the wall outlet before
making any connections.
• Read the instructions supplied with your speakers.
• Pay close attention to speaker wiring polarity. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) termi-
nals. If you get them the wrong way around, the sound
will be out of phase and will sound unnatural.
• Unnecessarily long or very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the
positive and negative wires.
Doing so may damage the AV
receiver.
• Don’t connect more than one
cable to each speaker termi-
nal. Doing so may damage the
AV receiver.
• Don’t connect a speaker to several terminals.
