SOURCE ENGINEERING NOISE SUPPRESSOR 1977 VINTAGE STEREO HISS POP REMOVER

Description

This circa-1977 Source Engineering Noise Suppressor is in excellent cosmetic condition and measures 11" x 10" x 4". I do not know exactly how its supposed to function, but I tested it to the best of my ability and it seems to be working correctly. I plugged in a stereo audio source into the left and right inputs and sent the left and right outputs to my stereo. It has separate left and right suppression controls, and a separate mode selector. The suppression controls remove hiss from audio and makes music sound duller and a little quieter as you crank the knob all the way up. There are two separate rca outputs for both the left and right channels, I'm guessing for splitting, bypassing or tape recording. In any case, they have each been individually tested and all work.
