Speaker Configuration

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

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

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

Before using the AV receiver, you must specify which speakers are connected and their sizes (see page 32). To get the very best from your surround-sound system, you should also specify the distance between the listener and each individual speaker so that the sound from each speaker arrives at the listener’s ears at the same time (see page 49). In addition, you should set the level of each individual speaker to achieve an equal balance (see page 49.)

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.)

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. All you need to do then 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

6 ohms or higher. If you use speakers with a lower impedance, and use the amplifier at high volume lev- els 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 to only positive

(+) terminals, and negative (–) terminals to only nega- tive (–) 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.

•Don’t connect more than one cable to each speaker termi- nal. Doing so may damage the AV receiver.

•Don’t connect one speaker to several terminals.
