Class D product guide
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. Comprising a multi-channel digital modulator (ZXCZM800), feedback processors (ZXCZA200), and high power output stages, DDFA amplifiers achieving a THD+N of less than 0.004% and dynamic range of 118dB can be produced.
