Introduction

Welcome to the extrodinary world of Altec
Lansing high fidelity sound.

Designed like no other speaker system in
the world, the patented Altec Lansing
speaker system lets you hear digital audio
sound with your computer. 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 digital audio quality
you are used to hearing from a music CD.
These speaker systems can 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 ACS33 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”.

Power On/Off: Rotate the volume
control clockwise to turn power on and
counter-clockwise to turn power off. A
power indicator on the base of the right
satellite will glow to show power is on.

NOTE: The ACS33 must be installed close
to an AC Power Socket so that the power
cord plug can be easily pulled out to
disconnect the power.

Volume Up/Down: Turn the volume
control clockwise to increase volume and
counter clockwise to decrease volume.

Figure 1

The satellite speakers are magnetically
shielded to prevent color distortion on
video displays. However, the subwoofer
is not magnetically shielded and should
not be placed in close proximity to a
computer monitor or television.

When the ACS33 is not used with a
computer, it can serve as an amplified
speaker system for CD players, cassette
players and various video/audio sources
with excellent results.

Set Up
Instructions
(See Figure 2)

Do not insert the
AC power plug into
the wall outlet
until all
connections are
made.

The only requirement
to set up the ACS33 is
to insert the DIN
connector into the
input marked RIGHT
SPEAKER and to insert
the audio input plug
into the computer
audio output. For easy
insertion of the DIN
connector, notice that
the arrow on the
connector must face up
as shown in the
diagram.

Placement of Speakers

All stereo information is heard from the
satellite speakers. The subwoofer
contains no stereo information and sound
is non-directional. As a result, the
subwoofer does not necessarily have to be

LIME

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 is not magnetically
shielded and should not be placed near
video displays.
