Connecting Your Speakers—Continued

Speaker Configuration

For 7.1-channel surround-sound playback, you need seven speakers and a powered subwoofer.

The following table shows which channels you should use based on the number of speakers you have.

Number of speakers:	2	3	4	5	6	7
Front left	✓	✓	✓	✓	✓	✓
Front right	✓	✓	✓	✓	✓	✓
Center		✓		✓	✓	✓
Surround left			✓	✓	✓	✓
Surround right			✓	✓	✓	✓
Surround back*					✓
Surround back left						✓
Surround back right						✓

*If you’re using only one surround back speaker, connect it to the SURR BACK L terminals.

No matter how many speakers you use, a powered sub- woofer is recommended for a powerful and solid bass.

To get the best from your surround-sound system, you must set the speaker settings. You can do this automati- cally (see page 42) or manually (see page 77).

Speaker Connection Precautions

Read the following before connecting your speakers:

•You can connect speakers with an impedance of between 8 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 pro- tection 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.
