In a reproducing apparatus, an equalizing system including a plurality of elements to be controlled is arranged to have its equalizing characteristic simply variable by controlling, with a single parameter, the plurality of elements to be controlled. Further, circuit characteristics of the equalizing system which are based on resonance frequencies and quality factors (Q) are controlled by controlling the resonance frequencies and the quality factors (Q) through the control performed with the single parameter over the plurality of elements to be controlled.
