Attaching the Speaker Cable Labels
The speaker terminals are color-coded for identification
purpose.
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:
• 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 54
). 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
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.
Using Dipole Speakers
You can use dipole speakers for the surround and surround
back speakers. Dipole speakers output the same sound in
two directions.
Dipole speakers typically have an arrow printed on them to
indicate how they should be positioned. The surround
dipole speakers (a) should be positioned so that their
arrows point toward the TV/screen, while the surround
back dipole speakers (b) should be positioned so that their
arrows point toward each other, as shown.
