PRO SWS-250 Multimedia Amplified Speaker System
Your OPTIMUS PR O SWS-250 Multimedia Amplified Speaker S ystem w ith
subwoofer and satellite speakers is
designed to enhance your computer
multimedia system, or transform your
portable CD player, or personal cassette player into a complete music
system. This amplified speaker system is compatible with any audio
source with a
1
/8-inch stereo head-
phone or LINE OUT jack.
The system’s 5-inch subwoofer and 3-
inch satellite speakers produce excellent stereo and powerfu l ba ss sounds.
You can use the sound output from
your computer and CD or cassette
player at the same time, and you can
connect a microphone to the system
so you can use it as a PA or Karaoke
system.
SPEAKER PLACEMENT
Speaker location and position are vital
for the best sound performance.
Satellite Speakers
For the best stereo image, the distance between the satellite speakers
should be about the same as the distance from the main listening area to a
point halfway between the speakers.

If you place the satellite speakers to o
far apart, a soun d “hole” could occur
and you might not get the proper stereo image in the l istening area. Compensate for this by angling the
speakers slightly in toward the listening area.
If you place the satellite speakers to o
close together, you could cancel out
the stereo image and the sound might
seem to be monaural. Compensate for
this by angling the speakers slightly
away from the listening area.
Subwoofer
Where and how you position your subwoofer greatly affects its bass response.
Although low frequencies are non-directional, factors such as room acous tics, standing waves, resonance, and
absorption strongly affect your subwoofer’s performance. For maximum
bass output, place your subwoo fer in
a corner. To reduce its outpu t, mov e it
away from corners and back walls.
Even slightly moving the subwoofer
can have a major effect on bass response.
Adjusting the subwoofer’s sound level
in relation to the satellite speakers’
volume affects your speaker system’s
overall sound. We recommend you
test the subwoofer in different locations to get the best ba lance between
your satellite speakers and the subwoofer.
We also recommend you place the
subwoofer at least 2 -3 feet away from
your monitor or computer so the subwoofer’s magnet does not distort the
colors on your monitor picture or
erase your disks.
CONNECTING THE
SYSTEM

input sources to the syste m:
• A computer ’s sound card
