Abstract

PURPOSE: To make an automatic adjustment of equalizer characteristics in accordance with the kind of a tape by automatically operating a switch corresponding to a reproduction level detection value obtained by a level detector by recording and reproducing a reference frequency signal by a standard bias current.
CONSTITUTION: Reference frequency oscillator 1 applies a bias current, adequate for a standard tape, to a reference freqency signal for recording and reproduction. This reproduction output level is detected by level detection circuit 7; when tape 4 is not a standard tape but different one such as a chromium tape, ttansistor Q3 of circuit 7 conducts to set FF31 and transistor 32 also conducts to change over bias- current change-over switch 13A and characteristic-adjusting switches 13B and 13C of recording and reproducing equalizers 2 and 6 through relay 18. As a reslt, an automatic adjustment of equalizer characteristics to the best value is made corresponding to the kink of the tape, in addition to the bias current.
