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 increase 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.
