Abstract

PURPOSE:To achieve a distortion rejector which stably operates over a broad band, by inserting a high-cut filter to a positive feedback circuit given to a power amplifier of negative feedback constitution from a noninverting input terminal of a load. CONSTITUTION:A speaker 14 is connected to a positive phase output terminal O and a negative phase output terminal P of a power amplifier 11 of negative feedback constitution via connection cords 131, 132. Positive feedback is given to an input terminal of an amplifier 10 from the input terminal R of the speaker 14 via a feedback cord 15. This positive feedback circuit consists of resistors R1, R3 and R4, and a capacitor C is connected between the connection point of the resistors R3, R4 and ground to constitute a high-cut filter 17. This high-cut filter 17 prevents instable operation due to the increase in the positive feedback voltage at high frequency region, allowing to keep the distortion rejecting effect with a broad band.
