ABSTRACT:
A recording media playing apparatus including tonal response control circuit configured to control the tone of reproduced sounds, by controlling signal levels of frequency components in a plurality of frequency bands, which are set to divide the frequency range of audio signals read out from the recording media, to designated variation ratios. The apparatus further comprises a memory device, a memory control device for storing, in response to a reproducing-tone memorizing command, data representing the variation ratios in the memory device correspondingly to identification information of each of the recording media, the data representing the variation ratios being stored as tone data, and a tonal response setting device for reading out the tone data using the identification information, the tone data corresponding to a recording medium to be played, and subsequently supplying the variation ratios represented by the tone data to the tonal response control circuit, thereby setting the tone of the reproduced sound. With this arrangement, the tonal response of the apparatus can be set automatically according to the type of music selections to be played.
