Optimus 1000 Oiled Walnut Speaker System
(400-1130)                Connections                 Faxback Doc. # 52878

The Optimus 1000 is equipped with easy-to-connect spring-loaded push
terminals. Simply remove 1/4 to 1/2" of insulation from the end of the
wire, press the terminal tab, insert the bare wire, and release the tab.

The size (gauge) of the wire you should use to connect your speakers
depends on the distance between the amplifier/receiver and the speakers.
For distances under 50' (15 m), we recommend 18-gauge wire - for distance
over 50', 16 gauge.  Always use the minimum length of wire necessary to
complete the connections.  Your local Radio Shack has a large selection of
speaker wire.

PHASING

Proper "phasing" is important when connecting the speakers.  Phasing means
that the + terminals on the speakers must be connected to the + terminals
on the amplifier/receiver (and - to - , of course).

Speaker wire has a mark on its conductors to help you with phasing.  This
mark may be a ridge or colored stripe along the insulation of one
conductor.  Or the insulation might be clear and the actual wires will be
two different colors (silver and copper).

In any case, connect the marked wire between + on the amplifier receiver
and + on the speaker; then connect the unmarked wire between - and -.

Improper phasing will diminish the performance of the speakers -
especially the bass response.

SPEAKER PLACEMENT

The position of the speakers has a great effect on their bass response.
Placing a speaker on a shelf or table or against a wall increases the bass
slightly.  In a corner or on the floor will increase the bass more.  For
maximum bass response, place the speaker on the floor and in a corner.

With stereo systems, the distance between the two speakers is important,
too.  Too great a distance causes a "hole" in the middle of the sound; too
small a distance decreases stereo effect.  For best results, the distance
between the speakers should be about two-thirds of the distance between
the speakers and the main listening area.

If the speakers must be further apart, turning them in slightly might
produce a better effect.  A little experimenting will soon reveal the best
set-up for your room and system.

PROTECTING YOUR INVESTMENT

The speaker cabinet and grille require periodic maintenance for optimum
appearance and performance.  Treat the enclosure as you would any fine
piece of furniture.  Don't place objects on top of the enclosure - this
might mar the finish.  To protect and enhance the finish, we recommend
using a high quality furniture polish.

Periodically clean the grille assemblies using a feather duster to remove
accumulated dust.  Do not use a vacuum cleaner on the grille unless you
remove it from the cabinet first.  The grille can be removed by grasping
the corners and gently pulling it out.  Never vacuum the actual speaker
elements - use a feather duster, gently and sparingly.
