GENERAL DESCRIPTION
SPECIFICATIONS
The Soundmask SM-GS-3200 is a microcontroller
controlled digital random noise generator with an
effective frequency range of 20Hz to 20kHz. The
digitally generated Gaussian noise is passed through
a Spectrum Shaper to flatten its response through
the midrange, corresponding to human speech
frequencies. The random noise is amplified through a
50W full bridge digital amplifier capable of driving 50
Soundmask speakers. The device’s output can also
be adjusted to ramp up when the device is switched
on for a more acoustically comfortable start up.
The generator has an external power supply (refer
below).
The SM-GS-3200 is small enough to use virtually
anywhere, and can hook in with a variety of different
speaker set-ups. It can be connected with all
Soundmask transducers.
