Introduction
Welcome to the extraordinary world of Altec Lansing
Multimedia high fidelity sound.
The patented Altec Lansing Multimedia Computer Speaker
Systems are designed like no other speaker system in the
world. 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 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 ACS95W is an amplified speaker system designed
especially for Multimedia Computer near field monitoring.
A unique feature of the amplifier is a patented dynamic
control circuit that automatically boosts bass at low volume
to maintain musical “realism” and a second bass boost
circuit that enhances bass response at all times.
The speaker enclosures are ported for maximum low
frequency response and are magnetically shielded to prevent
color distortion on video displays.
ACS95W Connections
(see Figure 1)
Figure 1 shows the connections that must be made to make
the ACS95W operative. Plug the DC power adapter in the
wall outlet after all other connections are made.
Insert the white speaker plug into the output jack marked SPKR
OUT.
Plug the green stereo audio cable into INPUT on the satellite
and to the sound card audio output on the rear of the
computer which is also green.
You are now ready to enjoy your new speakers. Turn on the
power by rotating the Volume Control clockwise to a
comfortable listening level. Further details on the controls
can be found in the next section.
A headphone jack is provided for private listening. When a
headphone is inserted into the headphone jack the speakers
are disconnected. The headphone jack is located on the right
side of the right hand satellite.
Use of Controls
•Volume Control/Power Switch. Rotate the control
clockwise to turn power on and raise volume for both
speakers. An indicator will glow to show power is on.
•Treble Control. Rotating the control clockwise increases
treble (High Frequency) response by 7dB. Rotating the
control counterclockwise reduces treble response by 7dB.
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 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.
•Make sure the power switch on the satellite 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 from the speaker
sound can cause other loose objects to vibrate. These
extraneous vibrations may lead to the erroneous
conclusion that the speakers are defective. In most
instances, removing the vibrating object cures the
problem.
•Double check to make sure that the speaker cable is
connected to the “ “ (out port), NOT the microphone
port, of the sound card.
