Connecting Your Speakers

Speaker Configuration
The following table indicates the channels you should use
depending on the number of speakers that you have.
For 7.1-channel surround-sound playback, you need seven
speakers and a powered subwoofer.

*1 If you're using only one surround back speaker, connect it to
the SURR BACK OR FRONT HIGH L terminals.
*2
Front high and surround back speakers cannot be used at the
same time.
If you use 4 or 5 speakers, connect each of the two sur-
round speakers to the SURR L/R terminals. Do not con-
nect them to the SURR BACK OR FRONT HIGH L/R
or FRONT HIGH OR ZONE 2 L/R terminals.
No matter how many speakers you use, a powered sub-
woofer is recommended for a really powerful and solid
bass.
To get the best from your surround sound system, you
need to set the speaker settings. You can do this automati-

Speaker Connection Precautions
Read the following before connecting your speakers:
• (North American models) You can connect speakers
with an impedance of between 6 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 protection circuit may be activated.
• (European and Asian models) You can connect speak-
ers with an impedance of between 4 and 16 ohms. If the
impedance of any of the connected speakers is 4 ohms or
more, but less than 6 ohms, be sure to set the minimum
speaker impedance to "4ohms"
speakers with a lower impedance, and use the amplifier
at high volume levels for a long period of time, the built-
in protection 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. In other
words, connect positive (+) terminals only to positive (+)
terminals, and negative (–) terminals only to negative (–)
terminals. 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.
• Make sure the metal core of the wire does not have con-
tact with the AV receiver's rear panel. Doing so may
damage the AV receiver.
