Introduction
Welcome to the extraordinary world of
Altec Lansing Multimedia high fidelity
sound.
The patented Altec Lansing Multimedia
Computer Speaker System provides the
best computer audio possible. You can
plug these computer speaker systems
into a PC audio card and vastly enhance
any business presentation, training,
education or advertising, music or video
production with the same level of audio
quality you are used to hearing from a
music CD. These speaker systems can
also be used with any multimedia home
computer, CD player or video
interactive game to provide a total
intelligent audio solution which is
practical and affordable.
Description
The AC45.2 is an amplified speaker
system featuring a subwoofer for
extended low frequency response. The
system is especially designed
for multimedia computer near field
monitoring.
A patented control circuit automatically
boosts bass at low volume to maintain
musical sound “realism.”
Electronic up/down controls adjust
system volume. The subwoofer has a
separate volume control for blending the
subwoofer level with the satellites to
the listeners preference.
The satellite speakers have a detachable
base that allows the speakers to be
angled upwards if desired for better
directivity of sound.
The satellites are magnetically shielded
to prevent distortion of monitor images.
Please note, that the subwoofer is NOT
magnetically shielded
and should not be placed in close
proximity to
the monitor.

playing a wide variety of music and

• On/Off Switch: The unit is turned
on/off by pressing both the up/down
volume controls simultaneously.
• Volume Up/Down: Volume is
controlled electronically by the use of
two push buttons located on the top of
the right satellite. Arrows on the push
button indicate volume up/down. The left

Placement of Speakers
All stereo information is heard from the
satellite speakers. The subwoofer
contains no stereo information and the
sound is non-directional.
As a result, the subwoofer does not
necessarily have to be placed in any
particular relationship to the satellites.
Placing the subwoofer on the floor close
to a wall or corner of a room, provides
maximum bass efficiency. The subwoofer
can be placed below tables, behind
couches and on bookshelves, etc.
The satellite speakers are magnetically
shielded and can be placed close the other
computer monitor without distorting the
video image. Best stereo effect is obtained
by placing speakers as far apart as the
cord set allows.
Troubleshooting
When first installing a new system, some
simple instructions may be overlooked
which can cause the unit to be
inoperative. Please make the following
checks:
• Make sure all connecting plugs between
the satellite speakers, subwoofer (if
applicable) and computer are fully
seated.
• Make sure the wall power outlet or
power strip has power. The outlet can be
checked with a lamp or some other
appliance. If the power strip has a
switch, make sure it is turned on.
• It is possible to test the unit by pulling
out the audio cable that is connected to the
computer and connecting it to an
alternate audio source such as a portable
CD player.
• When the unit is operative, vibrations
may lead to the erroneous conclusion that
the speakers are defective. In most
instances, removing the vibrating object
cures the problem.
