PURPOSE:To raise a tone quality of a recording/reproducing sound and to improve its articulation by using a capacitor which uses gas as a dielectric, or holds a space between electrodes in a vacuum, for an electronic circuit. CONSTITUTION:A coupling circuit containing a C10, resistances R10, R11, and an FETQ10 is constituted. Also, an equalizer containing capacitors C20, C21 and resistances R20, R21 is constituted. Moreover, an LPF containing capacitors C30-C34 and coils L30, L31 is constituted. As for the capacitors C10, C20, C21, and C30-C34 of each electronic circuit constituted in this way, a capacity fixing type capacitor which uses gas a dielectric, or holds a space between electrodes in a vacuum is used. In this way, a non-linear phenomenon caused by the capacitor is eliminated, and an elevation of a tone quality of a recording/reproducing sound and an improvement of the articulation are attained. |
