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 2channels 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 contactclosures, 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.
