Description

crop и корректирующую цепь, выход которой соединен с дополНИтельным входом усилител , отличающеес  тем, что, с целью повышени  качества звуковосироизведеии , в иего введены аттенюатор, элемент сравнени  и форсирующее звено с измен емой посто нной времени, при этом обща  точка последовательно соединенных резистора и громкоговорител  через форсирующее звено св зана с первым входомcrop and a correction circuit, the output of which is connected to an additional amplifier input, characterized in that, in order to improve the sound and sound quality, an attenuator, a reference element and a boost link with a variable time constant are introduced, with a common point of series-connected resistors and a speaker through the boost link is connected to the first entrance

элемента сравнени , выход усилител  через аттенюатор соединен с вторым входом элемента сравнени , выход которого св зан с входом корректирующей цени.the reference element, the output of the amplifier is connected via an attenuator to the second input of the reference element, the output of which is connected to the input of the correction value.
