Connecting the AV receiver—Continued
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. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only 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.
• Don’t connect more than one
cable to each speaker
terminal. Doing so may
damage the AV receiver.
• Don’t connect a speaker to several terminals.
