Positioning the Speakers

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.

Where you place your speakers 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 speaker 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
Radio Shack store.

The distance between the speakers should be about the same as the distance
between the normal listening point and the point halfway along a line
between the speakers.  If you place the speakers too close together, you
reduce the stereo separation.  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 A or B speakers
at the front of your listening area, and place surround speakers behind
or to the sides of the listening point.  See "Using Surround Sound."
Also, place the center speaker above, below, or behind the TV.  Sound
might not appear to coinside with the picture if you place it next to the
TV.

Connecting the Speakers

Follow these guidelines when you select and connect speakers.

Use speakers with an impedance of 8 to 16 ohms.

Be sure you properly connect all speakers.

Do not connect two pairs of speakers to a single set of terminals (A or B)
at the same time.  When you use two pair of speakers, connect one set to
Speakers A and one set to Speakers B.

Realistic, 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.

Use 16-guage (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 Wire

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.

Follow these steps to prepare the speaker wires.

1.  Cut the speaker wires to the necessary length.

2.  Separate the wires for about 4 inches on each end of the speaker wire.

3.  Using a wire stripper, carefully strip about 3/4 inch of insulation
    from the end of each conductor.

4.  Twist the end of each conductor to secure any loose wire strands.

Note:  Be sure you connect the receiver's right and left positive (+)
       and negative (-) terminals to the speaker's corresponding right
       and left positive (+) and negative (-) terminals.

Caution:  To prevent a short circuit, twist the end of each conductor to
          be sure that stray speaker wire strands do not touch other
          speaker terminals or any other receiver terminals.
