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

*2 Front high, surround back and front wide speakers cannot be used at the same time.

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 automati- cally (➔ 29) or manually (➔ 45).

Attaching the Speaker Cable Labels

The AV receiver’s positive (+) speaker terminals are all red (the negative (–) speaker terminals are all black).

Speaker	Color
Front left, Front high left, Front wide left,	White
Zone 2 left
Front right, Front high right, Front wide right,	Red
Zone 2 right
Center	Green
Surround left	Blue
Surround right	Gray
Surround back left	Brown
Surround back right	Tan

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.

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” (➔ 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 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.
