Connecting Your Speakers

Speaker Configuration

For the best surround-sound experience, you should connect five 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
Front left	✓	✓	✓	✓
Front right	✓	✓	✓	✓
Center		✓		✓
Surround left			✓	✓
Surround right			✓	✓

No matter how many speakers you use, a powered subwoofer 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 automatically (see page 33) or manually (see page 54).

Connecting a Powered Subwoofer

Using a suitable cable, connect the AV receiver’s PRE OUT: SUBWOOFER to the input on your powered subwoofer. If your subwoofer is unpowered and you’re using an external amplifier, connect the PRE OUT: SUBWOOFER to the amp’s input.

Attaching the Speaker 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 labels are color-coded and you should attach them to the positive (+) side of each speaker cable in accordance with the above table. All you need to do then is to match the color of each label to the corresponding speaker terminal.

For North American model

•If you are using banana plugs, tighten the speaker terminal before inserting the banana plug.

•Do not insert the speaker code directly into the center hole of the speaker terminal.

Speaker Connection Precautions

Read the following before connecting your speakers:

•You can connect speakers with an impedance of

6 ohms or higher. 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. 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.

FRONT SPEAKERS A OTHERS

•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.
