Preparing Your Receiver

Caution: Make all the necessary connections before you plug in or turn on the receiver.

Normal Listening Point

•Surround speakers generally sound best if you position them above ear level.

•To avoid picture interference of a nearby TV, use magnetically shielded speaker systems. This is particularly important for the center speaker since it is usually located closest to the TV.

Where you place your speakers (not supplied) can make a noticeable difference in your system’s sound. The guidelines in this section will help you choose the best locations. After you use your receiver for a while, you might want to try different locations for your speakers.

Bass response depends largely on speaker location. For strong bass, place the speakers in the corners of the room. If you want even stronger bass, place the speakers directly on the floor. If the bass is too strong, move the speakers slightly away from the corners of the room, or raise them 6 to 18 inches off the floor. You can buy speaker stands at your local RadioShack store.

The distance between the speakers should be about the same as the distance between the normal listening point and the point halfway between the speakers. If you place the speakers too close together, you reduce the stereo separation. If you place them too far apart, you reduce the bass effect and create a hole in the middle of the sound.

Most speakers have a tweeter dispersion angle of about 60 degrees. Ideally, your listening position should be just inside the overlap area of the tweeter dispersion. You can angle the speakers toward you for better stereo effect.

To position your speakers for surround sound, place the front speakers at the front of your listening area, and place the (rear) surround speak- ers behind or to the sides of the listening point (see “Using Advanced Sound Options” on Page 22). Place the center speaker above, below, or behind the TV. If you place it beside the TV, the picture may not coin- cide with the sound.
