Abstract

PURPOSE: To enable to completely monitor the dynamic range entirely, by displaying the recording level based on the recording level corresponding to the noise level and the maximum output level at reproduction.
CONSTITUTION: The recording input 9 and output of the recorder 11 are corrected at the miximum output frequency characteristics correction circuit 13 via the selector 12, they are compared with the reference voltage 17 at the comparison circuit 16 via the rectifying circuit 14 and change and discharge circuit 15, and the recording level based on the maximum output level is displayed 18. Further, the signal through the audible sense correction circuit 20 displays 26 the recording level based on the noise level similarly as the above mentioned circuit via the frequency characteristics correction circuit 21 for noise. Thus, from the lower limit and to the upper limit of the dynamic range of a recorder can completely be monitored and the dynamic range of a recorder having narrow dynamic range can be used to the utmost.
