• Self-designed discrete R-2R module. R-2R Ladder Network DAC converts digital signals into analog signals through resistor network switching. Compared to the high-frequency 0-1 switching used in modern delta-sigma DACs, its conversion method is more pure and direct, resulting in natural sound. However, this architecture demands extremely stringent precision in the resistor network, making it not only costly but also technically challenging to achieve optimal performance.
• True-1 Bit Decoding. True-1Bit DSD D/A Converter with native support for DSD1024 (via 1²S interface), delivering an oversampling ratio 16 times that of SACD-standard DSD64 and 1024 times the data density of CD format. In DIRECT DSD mode, DSD signals are directly processed by the 1-bit switching array decoding circuit, completely bypassing PCM conversion. This pure hardware solution achieves direct translation of DSD bitstreams into analog signals, fully preserving the temporal characteristics and micro-details of the original pulse density modulation.
• GCLK-02 Clock Module. The GCLK-02 clock module incorporates advanced PLL technology, achieving 1Hz-level locking precision to deliver ultra-high-precision clock signal processing capabilities. This PLL technology adjusts output frequency through precise feedback mechanisms, ensuring exceptional stability and accuracy in both frequency and phase of the clock signal. External connection of a high-quality 10MHz clock further enhances audio quality. Interface: BNC, Input impedance 50 0hm, 0dBm-20dBm. CMOS square wave 0.2V-3.3V, Sine wave 0.5V-3.3V.
• FPGA Programmable Logic Chip. A digital integrated circuit capable of constructing self-defined logic functions. Exclusive technologies including clock management, 2nd PLL digital shaping, DOP demodulation, and PCM/DSD depop switch lay a solid foundation for exceptional sound quality.
• Passive Analog Preamplifier. The passive analog preamplifier features R-2R relay-based volume control for lossless adjustment, with an optional preamp-bypass direct output. lt can be directly connected to active monitoring speakers or pure power amplifiers, enabling convenient remote-controlled operation.
