Reverberation mixer circuit

Abstract

This invention relates to a circuit for mixing a direct audio signal with a reverberation signal. The circuit includes an amplitude control for the reverberation signal and an active gain producing element such as, for example, a field effect transistor (FET). The direct signal is applied to the element in a manner such that this signal is amplified by the element. The reverberation signal is applied to the element through the reverberation amplitude control in a manner such that, as the amplitude for the reverberation signal is increased by the amplitude control, the gain of the element for the direct signal is reduced, thus maintaining uniform output volume. Thus, the output from the element has both a direct signal component and a reverberation signal component, the direct signal component decreasing as the reverberation signal component increases.
