MG2500 Digital Sound
Sound Masking Processor
MG2500
The Atlas Sound MG2500 Sound Masking Processor is a digital pink-noise generator that includes a balanced line-level audio input and 2- channels of digital signal processing, all in a single rack-space unit. An extended ‘non-apparent’ repeat time of noise (200 minutes) and output delay with distance/delay calculation, per channel helps ensure the masking source will not be decoded in high security installations. The MG2500 includes two independent matrices for channel-to-channel mixing and balanced input & outputs on plug-in barrier strip connectors. Noise & audio levels, plus two channels of combined 1⁄3 octave & parametric equalization, EQ, gain management & delay, are adjusted via computer software (Windows 95/98/2000/XP/NT4). Sixteen presets can also be recalled via contact- closures, RS-232, or other remote control options. There are no manual controls on front panel, to prevent tampering. All programming software & serial cable included. UL Listed.
