Connecting Your Speakers

Speaker Configuration

For the best surround sound experience, you should con- nect five speakers and a powered subwoofer.

The following table indicates the channels you should use depending on the number of speakers that 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 sub- woofer is recommended for a really powerful and solid bass.

Using Dipole Speakers

You can use dipole speakers for the surround left and right speakers. Dipole speakers output the same sound in two directions.

Dipole speakers typically have an arrow printed on them to indicate how they should be positioned. The surround left and right dipole speakers should be positioned so that their arrows point toward the TV/screen, as shown.

Connecting a Powered Subwoofer

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

Attaching the Speaker Labels (Not North American models)

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

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