Abstract

Perfections in the circuit arrangements for controlling the gain of power amplifiers, connected to an electroacoustic transducer, characterized in that the arrangement comprises means for detecting the signal in the electroacoustic transducer, said means being connected in negative feedback to the input of the amplifier. Power or to a preamplifier stage of said power amplifier by means of a circuit comprising a photo-optical coupling. (Machine-translation by Google Translate, not legally binding)
