• Surround speakers generally sound

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 speakers behind or to
the sides of the listening point (see “Using Advanced Sound Options” on
Page 21). Also, place the center speaker above, below, or behind the TV.

Follow these guidelines when you select
and connect speakers.
• Only connect speakers that are rated
at between 8 and 16 Ohms.
• Be sure you properly connect all
speakers.
• Do not connect t wo pairs of speakers
to a single set of terminals at the
same time.
• Realistic, Optimus, and other highquality 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.
• Use 16-gauge (or larger) speaker wire
for all speaker connections, and consider possible speaker locations before you decide how much speaker
wire you need.
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.

Connecting a Subwoofer Amplifier
Y our receiver includes a line-level subwoofer output. Connecting a subwoofer to
your system dramatically extends bass response for incredible richness and
depth. When you listen to surround-sound programs, a subwoofer enhances
your home theater experience by realistically re-creating the rumble of an earthquake, the bone-jarring percussion of a cannon, and more. To use the subwoofer output, simply connect
line-level input or to an amplifier to which you have connected a subwoofer.

Connecting a Subwoofer Amplifier
Y our receiver includes a line-level subwoofer output. Connecting a subwoofer to
your system dramatically extends bass response for incredible richness and
depth. When you listen to surround-sound programs, a subwoofer enhances
your home theater experience by realistically re-creating the rumble of an earthquake, the bone-jarring percussion of a cannon, and more. To use the subwoofer output, simply connect
line-level input or to an amplifier to which you have connected a subwoofer.
