ABSTRACT:
In a signal reproducing device such as an R-DAT video tape recorder, a digital signal recorded on the recording medium is reproduced by the magnetic head, stored in a memory, processed by a processing circuit, and converted into an analog signal by a D/A converter, and a detector detects whether or not the reproduction signal outputted by the head is present so that, according to the output of the detector, a muting circuit mutes the digital-to-analog converted signal and a driver suspends the operation of a level meter adapted to display the level of the digital signal, whereby the production of noise signals and the abnormal display of signal levels are prevented.
