A revolution in high-end audio

MUETA® is the most significant development in class D amplifier technology in decades, and a breakthrough for high-end audio. It not only combines the ultra-high efficiency of class D with the awe-inspiring audio quality of high-end amplifiers, but it also enables cost-effective products to be built without compromising specifications.

MUETA® class-D

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.

Patented audio technology

The MUETA® solution was developed and patented by the Eindhoven University of Technology (The Netherlands). MUETA (Wijk en Aalburg, The Netherlands) has the worldwide rights to use the technology in audio applications, and has developed an integrated controller IC and audio power amplifier evaluation boards for delivering up to 1000W per channel. These amplifiers are a fraction of the size of conventional power amplifiers as virtually no heat sink is required. The ICs are suitable for home entertainment, in-car audio, professional sound reinforcement and public address applications.
