A method of analysis of sound reinforcement problems by means of active and passive speech zones is outlined. The need for automatic control of multi-mike systems is defined, along with the problems associated with the use of voice-operated switches. Adaptive threshold gating is proposed as the best solution to the problem of active microphone detection. The development and performance of two effective automatic control systems is described.
