Background
 

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.

Development history

The MUETA® breakthrough was actually inspired by America’s desire for air-conditioning! Engineers were looking at ways to control generators to meet the unpredictable demand for power for air conditioners, and a class D amplifier is, after all, nothing more than a ‘voltage-controlled voltage source’. The circuit they designed was so strong, it stalled the combustion engine when being overloaded! Armed with ideas from this non-audio discipline, the Eindhoven University of Technology closely studied the classic shortcomings of class D from a radically different angle. After designing, verifying and patenting the solution, the University licensed MUETA® to develop a commercially viable product for audio applications. By applying its experience in designing, manufacturing and marketing high-quality audio products, and by using fast new components, many of which became available thanks to the explosive growth in mobile telephony, this company has succeeded in producing a range of MUETA® products.

The ‘MUETA’ name

The MUETA® name is derived by combining the Greek letters Mu (µ, commonly used to designate amplification factor) and Eta (η, commonly used to designate efficiency).
