Abstract

PURPOSE: To facilitate confirmation of a recoridng level and a reproducing level by performing level matching with a bar graph meter in a tape recorder, etc.
CONSTITUTION: The input level of test signal a of a fixed level and the level of reproducing signal 9, which is obtained by recording and reproducing test signal a on tape T, are displayed on bar graph meter 12 by 18 and 19, and levels 18 and 19 are caused to match each other, thereby performing level adjustment. In this case, output wave b of FF13 is used to turn on and off transistor 14, and the peak value of signal rectifier circuit 15 is discriminated to flash only pertinent element 19, thus adjusting recording input adjustment resistance 4 to facilitate level matching.
