ABSTRACT:
A magnetic cassette recorder is disclosed which has a microprocessor having stored therein a standard recording level. Inputting a signal representative of an actual amount of attenuation being offered by a level control rheostat to the input record signal, and a signal representative of the amplitude of the record signal that has traveled through the rheostat, the microprocessor computes the actual amplitude of the record signal before being attenuated by the rheostat. When the thus computed amplitude of the input record signal exceeds the stored standard amplitude, the microprocessor puts out a control signal for adjusting the rheostat to the standard amplitude. The standard recording level stored in the microprocessor is manually variable by switches to the liking of the particular user.
