SPEAKER PLACEMENT

For the best stereo image, place a pair
of speakers so the distance between
them is about the same as the dis­tance between the listening area and
the point halfway betwee n the speak­ers.

If you must place the speakers fa rther
apart, turn them slightly inward. If you
must place them closer to each other,
turn them slightly ou tward. Experi ment
with your speakers’ placement to find
the best location for them.

CONNECTIONS

Your local RadioShack store has a
wide selection of speaker wire. We
recommend you use color-coded or
marked wire to help you cor rectly co n­nect the wire. Most c olor-coded wires
have a stripe running down one of th e
conductors and marked wires have
ridges along one of the conductors.

With the speaker in its approxi mate lo­cations, measure the distance from
each speaker to yo ur receiver/amplifi­er.

Cautions:

• Take care never to exceed the
speaker’s maximum power rating
(see “Specifications”).

• To avoid any damage to the
speaker or amplifier/receiver, turn
off the amplifier/receiver before
making connections.
