Abstract

PURPOSE: To secure a recording which does not exceeds the maximum recording level for each band, by giving a control to the recording level so that the maximum level of the band where the difference becomes maximum between the maximum level of the band-divided record signal and the maximum recording level of the band may be the maximum recording level of the band.
CONSTITUTION: The input signal receives a band division through the HPF12 and the LPF13 and then a comparison through the differential amplifiers 24 and 26 the reference levels of which are set according to the maximum recording level after the peak of the maximum output which continues more than a prescribed time with every band is held. Then the diode 27 or 28 corresponding to the larger comparison output conducts, and then the recording level control circuit 4 is set so that the maximum output of the band where the difference is large between the maximum output and the maximum recording level may be the maximum recording level of the band. Accordingly, the recording level of the band which is not selected does not exceed the maximum recording level of the band. As a result, the reproduction level has no sudden reduction, thus securing the good recording and reproduction.
