features a compact enclosure utilizing two efficient wide range 2" x 4" speakers that are
powered by an internal 12 W amplifier channel. Selectable White and Pink Analog generators
are a incorporated to allow maximum masking design flexibility. A variable Hi-Cut filter to
contour the masking noise to the environment. The AM1200 also features an external 12 W
70.7V amplifier output to drive other 70.7V speakers, such as the Atlas Sound M2000, making
it ideal for small installation that require a self-contained system.
The AM1200 amplifier channels are a highly efficient Class D topology and are powered by an
external in line UL rated 24VDC power supply. There are separate internal and external level
controls to provide system balancing. All controls are recessed tamper proof screw drive type
potentiometers.

AM1200 can be mounted to the wall or ceiling. If you need a single suspension point, two
removable hanger brackets are included for mounting.

Applications
Achieve acoustical privacy in open and partitioned office areas by installing Atlas Sound’s self-

sound into a environment to obscure ambient noise, thus achieving conversational privacy in
designated areas. The equalized masking sound lowers intelligibility and “masks” disruptive
outside sounds.
