Crossover distortion occurs in many amplifiers when the audio signal is “handed off” from an amplifier’s positive-going output device to its negative-going device and vice versa. This transition is never perfect, resulting in crossover distortion that is spiky in nature and rich in high-frequency distortion products. This is easily heard.
Moreover, the problem becomes more audible as the signal level decreases. The more delicate the music, the more it will be masked and obscured by crossover distortion. THX’s patented distortion-reduction circuit reduces crossover distortion to vanishingly low levels (less than 0.0001% @ 1 kHz), resulting in a more accurate reproduction of the original content.
