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

Positioning Speakers

Halfway Point

Person in Listening Area

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

• To avoid interference with the picture on 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.

Between Speak

a=b

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 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 A or B speakers at the front of your listening area, and place the surround speakers behind or to the sides of the listening point (see “Using Advanced Sound Options” on Page 20). Also, place the center speaker above, below, or behind the TV. Sound might not appear to coincide with the picture if you place it beside the TV.

• Optimus and other high-quality speakers have color-coded speaker terminals (red for positive polarity and black for negative polarity). Use these color-coded terminals as a guide to help you properly connect the speakers to the receiver.

Preparing the Speaker Wires

Speaker wire consists of two conductors (individual wires) encased in insulation and is usually color-coded or marked with a ridge along one side so you can identify each conductor. Use these markings as a guide to help you properly connect the speakers to your receiver.
