for 5.1-channel surround.
• 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.

• Read the instructions supplied with your speakers.
• By default, speakers for 7.1-channel surround are
configured to use: front right/front left/center/
surround right/surround left/surround back right/
surround back left/subwoofer.
■
Screw-type speaker terminals
Strip 1/2" to 5/8" (12 to 15 mm) of insulation from the
ends of the speaker cables, and twist the bare wires
tightly, as shown.
■
Banana Plugs (North American models)
• If you are using banana plugs, tighten the speaker
terminal before inserting the banana plug.
• Do not insert the speaker code directly into the
center hole of the speaker terminal.
■
Speaker Connection Precautions
• You can connect speakers 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 ” (
➔
page 58 ). 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.
• 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.
Before connecting the power cord, connect all of
your speakers and AV components. A setup wizard
is launched upon first-time use to let you perform
the settings.
