Delivering high power quality audio with the efficiency of Class D

Class D architecture has been around for many years, but historically efficiency gains have been at the expense of audio quality. Now the advantages of Class D with sonic performance that truly rivals that of prestige linear amplifiers.

Digital revolution
Direct Digital Feedback Amplifier (DDFA™) technology digital input enables switching amplifier solutions capable of producing outstanding sound quality. DDFA describes the unique, exceptional performance, closed loop architecture of these amplifiers.

 

 DDFA amplifiers

Analog performance
The ZXCD series controllers form the heart of quality analog input switching amplifiers. Combination of ZXCD devices with high performing discrete MOSFET based output stages provides the best performing solutions in subwoofer and full band applications.

 

 Analog input amplifiers

Market sectors
The proliferation of digital sources means that digital power amplifier technology is particularly well suited to specific market sectors. The benefits in quality audio performance, high efficiency and small size give clear advantages.
