Sound-Effects Track Noise-Suppressor
A simplified noise-suppressor for the effects track in CinemaScope reproduction operates in the speaker line, thus using the full gain of the system, and uses two tuned circuits: one accepts and rectifies the 12-kc control tone to operate a speaker relay, and the other rejects the 12-kc tone from the wanted program material in effects speakers. The unit uses no tubes or power supply.
