Abstract

PURPOSE: To make easy adjustment for recording level and EQ by recording the signal adjusted with the variable means which changes the level of a given signal on the tape and comparing the signal reproduced with the reference voltage as DC voltage.
CONSTITUTION: In adjusting the recording level, the switch S2 is selected to the test position and the switch S1 is to the level position and the signal in 400 Hz is fed to the input of the line amplifier 1. The signal is recorded on the tape 8 by turning the adjusting knob of the level adjusting circuit 2. The recorded signal simultaneously reproduced with the reproducing head 9 and converted into DC level with the rectifying circuit 11 and the smoothing circuit 12 is compared with the reference voltages V1 and V2 by the comparison circuit 14. In this case, when the diode D2 is illuminated, it shows the recording level is suitably adjusted, but if the diode D1 or D3 or D3 is illuminated, it shows the reocrding level is small or large.
