The SMG-1R is a sound-masking generator with a 1RU rackmount chassis. This generator-only model produces a digital noise signal (pink or white) for masking system applications that utilize a separate amplifier, or amplifiers, to drive the masking speakers. The generator produces a digital output signal for sound-masking that is pink noise (equal energy/octave) or white noise (equal energy/frequency). The selected noise signal is fed to the masking speakers to produce the characteristic "whoosh" sound that "masks" ambient noise in a properly designed masking system to create conversational privacy
