Abstract

PURPOSE:To achieve a distortion rejector with stable operation, by giving a positive feedback to a negative feedback amplifier from an inverting input terminal of a load and setting the impedance of noninverting and inverting output lines equal. CONSTITUTION:Conductor patterns 221-225, output coil 231, protective relay contact 232, and selector switch 233 are inserted between inverting and noninverting terminals M, N of a power amplifier 21 of negative feedback constitution having an amplification factor A and inverting and noninverting output terminals O, P of an amplifier 20. A speaker 14 is connected to the output terminals O, P of the amplifier 20 via connection cords 131, 132 and the positive feedback of the feedback rate -alpha is given from the noninverting input terminal R of the speaker 14 via a feedback cord 15. Impedances ZA, ZB between the terminals M-O and N-P are set equally, and when the impedances Z1, Z2 of connection cords 131, 132 are equal, the feedback rate can always be taken as 2/A with equation (4) which maximize the distortion rejecting effect.
