Abstract

PURPOSE:To improve distortion when a large input deviating greatly from the selection characteristics of a variable gain amplifier arrives, by switching output levels by varying a gain control signal. CONSTITUTION:An output reducing device 5 varies a gain control signal from a controller to decrease the intensity of an output appearing at an output terminal 3. Then, the intensity of the output appearing at the output terminal 3 is decreased by applying the signal to a control terminal 6, so that a variable gain amplifier 2 operates with a small gain. Therefore, distortion at the time of a large input is improved. The intensity of the output at the output terminal 3 is, however, kept small all the time, so the signal is supplied to the control terminal 6 to obtain the output having the same intensity with usual one normally except in said case.
