High-power solid-state amplifiers

Lloyd Preston Garner

Open publisher page 2 citations

Abstract

High-power amplifiers are needed, particularly in the area of sound reinforcement for public address and auditorium usage. Paralleling a number of amplifiers to obtain the required power level has never been a wholly satisfactory solution. This paper presents the design philosophies and goals achieved in two high-power solid-state amplifiers, rated at 150 and 330 watts, respectively. In addition, there is a discussion on unique electronic protection circuitry which these amplifiers contain, in order to protect the amplifiers and their associated equipments, in the event of system malfunction.
