Introduction
Welcome to the extraordinary 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 controlled 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 ACS295 is an amplified stereo speaker system featuring a subwoofer for extended low frequency response. The system is especially designed for multimedia computer near field monitoring. Two audio inputs (1) and (2) allow mixing of computer audio signals with other sources of sound. A patented

control circuit automatically boosts bass at low volume to maintain musical sound realism.
Electronic controls adjust system volume, bass and treble. The subwoofer has a separate volume control for blending the subwoofer level with the satellites to the listeners preference.
The satellite speakers are magnetically shielded and can be placed close to the monitor without disturbing images.
Subwoofer frequencies are non-directional, therefore the subwoofer does not have to be placed in any particular relationship to the satellite speakers. Placing the subwoofer on the floor close to a wall or corner of a room or under a desk gives excellent results The subwoofer speaker is not magnetically shielded and should not be placed close to the monitor.
When the ACS295 is not used with a Multimedia Computer, it can serve as an amplified speaker system for CD players, cassette players and various video/audio sources with excellent results.

Back View of ACS295 Components Showing Connection Between Units

Do not insert the AC power plug into the wall outlet until all connections are made as shown in figure 1.
· Before making connections, notice that the DIN connector plug, the stereo plug and the speaker mono plug are color-coded to prevent errors. This color coding corresponds to connectors found on the rear of the subwoofer, right speaker and computer.
· When connecting the red color-coded DIN connector into the SPKR OUT receptacle color-coded red on the subwoofer, notice that the DIN connector

has an arrow. The arrow should face up to make a proper connection. Press the connector firmly into the receptacle to make sure it is fully seated.
· The speaker mono plug colored white is inserted into the jack marked SPKR color-coded in white on the right satellite speaker.
· Insert the stereo plug colored green into the audio jack (input 1) color coded in green. Insert the plug on the other end of the stereo cable into the computer audio output. The ACS295 is now operational.

Use of Top Panel Controls on Right Satellite Speakers (See Figure 2)

· ON/OFF SWITCH: To turn the unit on, press the POWER switch. A yellow indicator next to the switch will glow to show the power is on. Press the switch again to turn the power off.
· MASTER ROTARY LEVEL CONTROL: The rotary master level control operates in two modes. Whenever the BASS or TREBLE function is selected, the volume level of that function can be adjusted up or down by the rotary control. Once each function is adjusted to the desired level, the mode of operation reverts to the rotary control after a short period. The rotary control then performs as a master LEVEL control adjusting the volume of all speakers simultaneously.

The green indicator will go out denoting the control has been reset. Once the green indicator is off, the master level control becomes operational.
Figure 2

·TREBLE/BASS CONTROLS: To raise or lower treble or bass response, press the switch next to each mode selector, a green indicator will glow to show the function is operational. Turn the ROTARY control clockwise to increase response and counter-clockwise to decrease response. Once the level is set, the indicator next to the function will turn off after a short period. Each function can be turned off quickly by pressing the function button a second time. To reset the Treble and Bass controls to their factory, preset (flat) position depress and hold the corresponding button for a period of approximately three seconds.

Placement of Speakers
All stereo information is heard from the satellite speakers. The subwoofer contains no stereo information and its 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 is not magnetically shielded and should not be placed near video displays.
The satellite speakers are magnetically shielded and can be placed close to the computer monitor without distorting the video image. Best stereo effect is obtained by placing the speakers as far apart as practical.

How to Enhance Presentations with Dialogue
A CD player or other audio source can be plugged into the unused INPUT. Mixing of the computer audio output with another audio source can be accomplished by using the volume control or ON/OFF switch on the second audio source. A typical example may be as follows:
A lecturer may want to interject dialogue into a multimedia presentation. If the lecturer has a wireless FM microphone system the output of the microphone receiver can be connected to the unused input on the ACS295. When the lecturer wishes to make a comment, he either turns on the microphone switch to speak or he can raise or lower the microphone volume control to mix his voice with the computer audio program. Any other audio device can operate in the same manner.
