Abstract
PURPOSE: To make it possible to set the best recording level automatically by setting the recording level through one-touch operation.
CONSTITUTION: With automatic setting switch 7 depressed, time setting circuit 6 is driven to generate a pulse of time width equivalent to the set time, which is applied to maximum-value holding circuit 5. Among levels detected by level detector 4, circuit 5 holds the maximum level within the time set by circuit 6 and supplies gain control circuit 3 and display unit driving circuit 41 with a control signal that corresponds to it. At this time, AGC switch 48 is closed by relay 47 and AGC circuit 49 provided to recording amplifier 45 is put into operation. Consequently, a signal applied to input 1 is controlled by AGC circuit 49 so that no matter what set value gain control circuit 3 has, namely, no matter how excessive the signal level of output 2 is, recording current flowed to recording head 46 via recording amplifier 45 will be within the range of proper recording levels.
