Connecting the AV Receiver
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-
cally (
➔
23) or manually (
➔
36).
Attaching the Speaker Cable Labels
The AV receiver’s positive (+) speaker terminals are all
red. (The negative (–) speaker terminals are all black.)
The supplied speaker cable labels are also color-coded and
you should attach them to the positive (+) side of each
speaker cable in accordance with the table above. Then all
you need to do is to match the color of each label to the
corresponding speaker terminal.
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” (
➔
40). 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 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.
