Abstract

PURPOSE:To enable the separation and audio quality adjustment with less number of circuits and elements, by controlling the share of the gain of the 1st and 2nd type amplifiers of frequency flat voltage control type and the 3rd amplifier of voltage control type having a low filter characteristic. CONSTITUTION:In case of a strong electric field, a control voltage is given to the 1st and 2nd frequency flat voltage control amplifiers 22, 25, and the auido signals of the left and right enter the 1st and 2n adders 27, 28 in flat with the gain and are output. In this case, the 3rd voltage control amplifier 23 having a low filter characteristic has no gain and zero output. On the other hand, in a weak electric field, the control voltage is given to the 3rd amplifier 23, the gain is given, the low band component of the sum of the left and right audio signals is amplified, it enters the 1st and 2nd adders 27, 28 and is output. In this case, the 1st and 2nd amplifiers 22, 25 have no gain and zero output.
