ABSTRACT:
A device for adjusting the frequency response characteristic of a magnetic sound recorder at relatively low and high frequencies, wherein the signal level of the recording signal to be supplied to the recording head of the recorder and the amount of compensation for the frequency response characteristic of the recording signal are adjusted by visual observation of a visible signal produced by one of electrically actuated light-emissive semiconductor elements which are to be selectively energized depending upon the relationship between the signal level of the playback signal and a reference signal which may be one of a plurality of predetermined reference signals or may be variable with the level of the recording signal.
