Self-developed adaptive clock system technology
Self-developed adaptive clock system technology, built-in 4 independent ultra-low jitter audio crystal oscillators, equipped with a femtosecond-level local clock system for the USB part, the standard version of the crystal oscillator is AS-318B, and the high version is CCHD- 957. SDA-6 supports external clock input, among which USB supports 10M clock input, and other interfaces support WCK input. In USB mode, it also supports 50 and 75-ohm switchable input impedance.
High-performance DAC Decoder
High-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the secondary PLL of external digital input jitter.
Rich input and output interfaces
It adopts 4 channels of fully balanced and full DC discrete circuit output; among them, the high-end version adopts non-loop negative feedback output. It has a wealth of input and output interfaces, including standard USB2.0 input interface, SPDIF and BNC coaxial and AES balanced input, HDMI-I2S input interface, analog output including XLR balanced output and RCA single-ended output; all interfaces support DSD input.
Multi-input channel isolation technology
Large-scale FPGA for digital audio signal processing, self-developed second-generation algorithm, original multi-input channel isolation technology, to ensure the purity of each input signal.
Adopts the latest AK4499 DAC chip
Built-in 40 watt custom O-type transformer, output 4 independent power supply windings, up to 20 groups of distributed voltage stabilized circuits; The DAC chip adopts the latest AK4499 released by AKM in 2019; DSD adopts the native direct solution mode. The DSD digital stream does not pass through the internal digital filter and works in the NOS mode, which is fully in line with the design concept of HQPlayer.
