ES9039SPRO X 2: Using two ESS flagship chips ES9039SPRO for Digital to Analog Conversion,1chip each for left and right channel. With two completely independent power supply and grounding to seal the great sound performance. DSP Digital Filter: A high-performance digital filter solution developed on the Analog Device SHARC digital audio-specific DSP platform with the primary objective of reducing audio in-band aliasing noise in the digital domain.This filter enhances the sound quality by upscaling and noise shaping the raw digital audio stream signal. The anti-aliasing noise algorithm and high-precision floating-point 64bit operation used in this program are the key technical points. FPGA Programmable Logic Chip: Exclusive technologies such as digital integrated circuits with self-constructed logic functions,clock management,2nd PLL digital shaping,DOP demodulation,and PCM/DSD depop switch provide a solid foundation for excellent sound quality. GCLK-02 Clock Module: The GCLK-02 clock module is a high-performance clock frequency synthesizer that utilizes advanced PLL(Phase Locked Loop) technology to ensure clock signal stability and accuracy. The design of this module allows it to use either a local clock source or an external 10MHz clock signal,providing users with a flexible clocking solution. In this way,the GCLK-02 is able to significantly reduce the impact of the front-end clock performance on the overall system performance,thus reducing the dependence on the performance of the front-end audio equipment. Hybrid IV conversion circuit: Independent parallel circuit-Fully meets ES9039SPRO's high current requirements
