All class D amplifiers are very efficient compared to the class A and class AB topologies generally used for audio amplifiers. However, ‘conventional’ class D technology has an inherently poor frequency response above 1kHz making it unsuitable for high-end applications. Various enhancements of class D amplification do exist, but these tend to come with limitations of their own and are very costly. The MUETA® solution uses proven new techniques to overcome all the drawbacks of previous class D amplifiers.
