Speaker Configuration
The following table indicates the channels you should use
depending on the number of speakers that you have.
No matter how many speakers you use, a passive
subwoofer 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 manually (

page 29).
Connecting the Speaker Cables
The AV receiver’s positive (+) speaker terminals are
color-coded for ease of identification. (The negative (–)
speaker terminals are all black.)
Speaker Connection Precautions
Read the following before connecting your speakers:
• 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.
• 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
contact with the AV receiver’s rear panel. Doing so may
damage the AV receiver.
• Don’t connect more than one cable to each speaker
terminal. Doing so may damage the AV receiver.
• Don’t connect one speaker to several terminals.
