Abstract

PURPOSE:To obtain a tone quality corresponding to an acoustic signal, by switching the characteristics of an amplifying circuit while interlocking with a changeover switch which selects acoustic signals of plural sequences. CONSTITUTION:When a function switch 11 is switched to the radio receiving part side and a band changeover switch 12 is switched to the band of an MW band, switches 17 and 18 are so switched while interlocking with these switching that band characteristics of a preamplifying circuit part 13 and a main amplifying circuit part 15 are flat up to low and middle bands. When switches 11 and 12 are switched to positions other than mentioned above, switches 17 and 18 are so switched that they are flat up to the high band.
