• DSP Digital Filter: Incorporates a high-performance digital filter solution based on the Analog Device SHARC digital audio-specific DSP platform. This filter reduces audio in-band aliasing noise, upscales, and noise shapes the digital audio stream signal using a high-precision floating-point 64-bit operation.
• FPGA Programmable Logic Chip: Features exclusive technologies including self-constructed logic functions, clock management, 2nd PLL digital shaping, DOP demodulation, and PCM/DSD depop switch, contributing to superior sound quality.
• GCLK-02 Clock Module: A high-performance clock frequency synthesizer employing advanced PLL (Phase Locked Loop) technology for stable and accurate clock signals. Supports both local and external 10MHz clock sources, reducing dependence on front-end audio equipment clock performance.
• Hybrid IV Conversion Circuit: Independent parallel circuit design fully meets the high current requirements of the ES9039SPRO chips.
• Network Bridge and Streaming: Supports Roon, Airplay, UPnP, NAA, and Spotify protocols with 100/1000Mbps LAN speed.
• Fully Balanced Design: Features a fully balanced design with complete four outputs.
• Dual High-Capacity Toroidal-Core Power Transformers: Isolated power supplies for digital and analog sections.
