Abstract

PURPOSE: To achieve circuit integration and make addition of an ALC circuit and automatic sound recording level tuning device easy by controlling the operation of a reversible counter with a switch and digitally displaying the output thereof.
CONSTITUTION: When a switch 36 is closed, a positive voltage 37 is applied to the terminal 8b of a reversible counter 8, by which the counter is counted up. The output thereof is supplied to the liquid crystal element of a display part 11, by which the count condition of the counter is displayed. At the same time, it is D/A converted 9 and inverted 43 to apply the control input to an electronic volume 2. The input recording sound signal 1b is subjected to low attenuation by the switch 2 and is then outputted. On the other hand, when the switch 39 is closed, the terminal 8b is grounded and the counter is counted down, the output whereof is displayed 11 and the attenuation quantity of the volume 2 is increased.
