Abstract
An audio system having a voice override and voice amplification control circuitry is provided. The system provides high quality music to a listener through a set of headphones and includes a microphone and a foot operated switch to allow a user to override the music signal to communicate with the listener. The foot switch initiates a ramp voltage signal generator which gradually attenuates the normal music signal to a predetermined level and gradually increases the level of the voice signal and mixes it with the music signal. When the voice signal terminates, the music gradually returns to its normal level when the foot switch is deactivated resetting the ramp voltage signal generator.
