Connecting Your Speakers—Continued

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 45). 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.
