Description
The 1ET6525SA is a single-channel, ultra-high-performance, analog-input Class D amplifier module capable of delivering over 450W of power. It sets a new benchmark for audio quality across all amplifier classes. By leveraging 2nd generation Eigentakt ErrorCorrection, it achieves the highest level of performance. Its compact size and exceptional reliability make it suitable for a wide range of applications, while its superior sound quality makes it the clear choice for applications where audio excellence is paramount.
PURIFI's ongoing research in nonlinear control theory has led to the development of the first mathematically precise large-signal model for self-oscillating amplifier controllers. This breakthrough enables the complete optimization of the feedback circuit, resulting in performance improvements of at least an order of magnitude over existing designs. Additionally, the amplifier module features a comprehensive protection system, ensuring robustness and ease of integration.
