The SMG-2 sound masking generator produces an analog pink noise signal that is fed to sound masking amplifiers (ordered separately) in order to produce random low-level background noise to mask ambient noise and aid conversational privacy.

The PRE-EQ OUTPUT has a flat spectrum that can be used as an input to equalizers that feed power amplifiers for masking systems that require precise equalization.

The POST-EQ OUTPUT is adjusted by bass, mid and treble controls, and can be used for less demanding applications that utilize basic spectrum shaping.
