![]() ![]() It is at the point at which the output moving from one transistor to another (the crossover point) that a small amount of distortion is created. ![]() In Class A amplification the output transistors are modulated by the audio signal to turn more or less ‘on’ but never actually turn off, however in Class B the output transistors actually at some point turn off as the output is passed from one transistor to another. Crossover Displacement Technology Ĭlass XD (or Crossover Displacement) is a proprietary and patented amplifier technology developed in-house by Cambridge Audio.įirst appearing in 2006 in the Azur 840A integrated amplifier, the Crossover Displacement design sought to combine the performance of a traditional Class A design with the efficiency of Class B but without the linearity and distortion limitations of Class AB. ![]()
