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,
be sure to set the speaker impedance to 4 ohms (see
page 57). 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. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) termi-
nals. 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.
• Don't connect more than one
cable to each speaker termi-
nal. Doing so may damage the
AV receiver.
• Don't connect a speaker to several terminals.
The following illustration shows which speaker should be connected to each pair of terminals.
If you're using only one surround back speaker, connect it to the SURR BACK L terminals.
