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 or 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 ACS22 consists of two amplified speakers especially designed for multimedia computer near field monitoring. The speakers are magnetically shielded so that
they can be placed close to a computer monitor without distorting images. Best stereo affect is obtained when the speakers are placed as far apart as the speaker cord
set allows.
When the ACS22 is not used with a computer, it can serve as an amplified speaker system for CD or Cassette players and various video/audio sources with
excellent results.
