An apparatus such as a television signal receiver provides an AGC function which reduces cross-modulation distortion. According to an exemplary embodiment, the apparatus includes a source of an input signal and a gain control circuit coupled to the source of the input signal. The gain control circuit provides a first control signal at a first level to a first amplifier while a magnitude of the input signal is within a first range and provides the first control signal at a second level to the first amplifier while the magnitude of the input signal is within
