BI-AMPLIFIER CORRECTION DEVICE, AND AV AMPLIFIER EQUIPPED WITH THE SAME

摘要

PPROBLEM TO BE SOLVED: To inexpensively achieve optimization of high sound-quality drive of bi-amplifier reproduction in two-channel stereo reproduction, by adding a simple change-over circuit and delay circuits to a multi-channel AV amplifier. PSOLUTION: This AV amplifier is structured such that the change-over circuit constituted of simple switches S1-S18 and the delay circuits 3a and 3b are added to an AV amplifier body, and speaker compensation is carried out, by using an automatic sound field compensating microphone system, thereby the sound quality at two-channel stereo reproduction can be improved, by effectively using an amplifier for multichannel reproduction in the two-channel stereo reproduction.
