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"
44). 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.
• Don't connect more than one cable to each speaker ter-
minal. Doing so may damage the AV receiver.
• Don't connect one speaker to several terminals.
