SPEAKER PLACEMENT

Correct speaker location and position are vital for best performance.  The
best location as a center speaker for a surround sound system is beneath
or on top of your TV/monitor.

For a stereo system, place it on a table or on a shelf positioned near a
corner of the room.  If possible, place the front edge of the PRO-7AV
flush with the front edge of the shelf.  For best sound, avoid floor
locations.  (Floor coverings can absorb much of the sound.)

We urge you to play a familiar, wide range music selection and experiment
with speaker placement until you find a speaker location that sounds the
best to you.

Stereo speaker placement can be a little tricky.  For the best stereo
image, the distance between the speakers should be about the same as the
distance from the main listening area to a point half way between the
speakers.  If the distance between the speakers is too large, you might
hear a hole in the center of the sound.  You can compensate for this by
angling the speakers slightly in toward the listening area.

CONNECTIONS

When you place the speaker in its approximate location, measure the
distance from the speaker to the amplifier.  Use speaker wire or
ordinary 18-gauge lamp cord (zip cord) for distances of 50 feet, or
less.  For distances greater than 50 feet, use heavier 16-gauge wire.

Speaker wire coded with a ridge or stripe on one side makes the
connection process easier.  Radio Shack stores sell speaker wire to meet
most needs.

Using the ridge or the stripe on the speaker wire as a guide, connect the
speaker's negative (-) terminal to the amplifier's corresponding negative
terminal (right, left, or center channel).  Then connect the speaker's
positive (+) terminal to the amplifier's corresponding positive (+)
terminal.

This connection procedure is called phasing.  Keeping your speakers in
proper phase is essential for maximum bass response and overall
performance.

1.  Remove the insulation from the ends of the wire using a wire stripper.

2.  Push down the tab on the speaker's negative (-) terminal and insert
    one of the wire ends.  Release the tab.

3.  Push down the tab on the speaker's positive (+) terminal and insert
    the other wire end.  Release the tab.  If you are installing two
    speakers for stereo, repeat this connection process for the right
    speaker.

USING THE RUBBER FEET

We provide self-adhesive rubber feet to help you avoid scratching your
furniture.

You will find two types of rubber feet.  Use the thicker ones for the
front of the speaker and thinner ones for the back of the speaker.

Remove the paper backing and press the feet onto the bottom of the
speaker.

ADJUSTING THE OPTIMUS BADGE

You can adjust the OPTIMUS badge for horizontal or vertical placement.
Pull out the badge and rotate it until it clicks stop.

MOUNTING THE PRO-7AV

Using the screw, you can mount the speaker directly on a wall.  Use a #10
or larger screw.

You can place PRO-7AV using a speaker stand (Cat. No. 40-2068 or 40-2069)
or you can mount the PRO-7AV in a vehicle, on a wall, under a shelf, or on
a ceiling, using a special bracket (Cat. No. 40-2067).  Follow the
instructions provided with the speaker stand or the bracket.
