    The Model 755 is an electronic signal processor designed to reduce or eliminate Audio Feedback in a Public Address System. It is in fact, a frequency shifter capable of continuously shifting the frequency of all signals passing through it, by as much as 6Hz. This shift is not typically audible unless it is compared to the original signal.
