PROBLEM TO BE SOLVED: To provide an ALC controller capable of performing appropriate ALC control without adding new components. SOLUTION: The ALC controller controls an AGC AMP (5) which turns input signals to a prescribed output signal level and outputs them. Then, the ALC controller calculates the D/U of IM (Inter Modulation) 3 on the basis of output signals, estimates an input signal level corresponding to the calculated D/U of the IM 3, and performs the ALC control on the basis of the output signal level corresponding to the input signal level.
