ABSTRACT:
A tape recorder comprises a noise reducing circuit provided at its output side with a first switch for changing over the circuit from its operative condition to its inoperative condition and vice versa and a second switch operatively connected to the first switch and for changing over the signal level. The use of the noise reducing circuit causes a decrease of the standard point of the recording level and an increase of the standard point of the reproduction level so as to increase the dynamic range of the tape recorder.
