Connecting Your Speakers

Speaker Configuration

The following table indicates the channels you should use depending on the number of speakers that you have.

For 5.1-channel surround-sound playback, you need five speakers and a powered subwoofer.

Number of channels	2	3	4	5
Front speakers	✔	✔	✔	✔
Center speaker		✔		✔
Surround speakers			✔	✔

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

To get the best from your surround sound system, you need to set the speaker settings. You can do this manually (➔ 30).

Attaching the Speaker Cable Labels

The AV receiver’s positive (+) speaker terminals are color- coded for ease of identification. (The negative (–) speaker terminals are all black.)

Speaker	Color
Front left	White
Front right	Red
Center	Green
Surround left	Blue
Surround right	Gray

The supplied speaker cable labels are also color-coded and you should attach them to the positive (+) side of each speaker cable in accordance with the table above. Then all you need to do is to match the color of each label to the corresponding speaker terminal.

•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.

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 imped- ance, 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. 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.
