Patent number: 4374300Abstract: A multiple program input audio system including a plurality of input channels each adapted to provide an output program signal. Each channel comprises an actuator which compares a rectified program signal with a reference signal and generates an actuator output signal when the rectified signal is greater than the reference signal. A zero crossing detector also receives the program signal and generates an initiator pulse when the voltage of the program signal is zero. A master control switch receives the actuator output signal and generates a first master control output signal when pulsed by the initiator pulse and generates a second master control output signal when no signal is received from the actuator. A program switch receives the program signal and in response to the first master control output signal applies the program signal to an audio program buss where the program signals from all the channels are summed and applied to a digital attenuator.Type: GrantFiled: October 18, 1979Date of Patent: February 15, 1983Assignee: Innovative Electronics, Inc.Inventors: Robert Ponto, Hardison G.
