INTRODUCTION
The Atlas Sound MG2500 Sound Masking Processor provides a digital pink-
noise generator, a balanced line-level audio input, and a 2-channel DSP

software. Sixteen presets can be recalled via contact-closures, RS-232, or
other remote control options. The MG2500 carries a five-year warranty.
