Descriptions:

> DSP Digital Filter

> The program is in the Analog Device SHARC digital audio

dedicated DSP platform has developed a new high-performance

digital filter program, equipped with self-developed high-performance anti-aliasing noise algorithms, the key digital signal processing links using high-precision floating-point 64bit operation. It can reduce the digital domain audio in-band aliasing noise, i.e., by doing frequency upscaling and noise shaping on the original digital audio stream signal, thus realizing better sound quality performance.

> Built-in OCXO constant temperature crystal oscillator

> Double insulation, more constant temperature.

> K2 Synthesizer Synchronized Clock Implant Technology

> Local OCXO clock or external 10M clock, synthesized a

high-precision clock signal and then synchronously implanted for decoding. The front-end clock is discarded, and the DAC only uses the local OCXO clock or external 10M clock.

> Because of these front-end clock performance on the decoding link greatly reduces the impact of the system on the performance of the front-end audio equipmept'to reduce the degree of dependence

> FPGA Programmable Logic Chip

> Digital integrated circuits with self-constructed logic functions, clock management, 2nd PLL digital shaping, DOP demodulation, PCM/DSD depop switch, and other exclusive technologies provide a solid foundation for excellent sound quality.

> l/V-convertor and parallel connection circuit convert the current from a DAC into an analog voltage, can fully meet the requirements of ES9039PRO high current.

> Analog LPF Circuit

> The analog LPF circuit is a discrete Class A circuit designed especially for the ES9039PRO chip. Since each discrete device only needs to consider its own performance individually, there are fewer application limitations for this one device alone, so the performance of a single component can be fully utilized. Because it is not like integrated circuits are integrated in the chip can not be separated and changed, the use of discrete devices is more flexible, you can freely adjust the parameters of each level, so that it achieves the best working condition, but also because of its greater part of the part also appears to be relatively controllable, you can give different decoding architecture to bring greater variability of the sound style.

> Passive analog preamp

> R2R relay volume adjustment without loss of sound quality, can also skip the preamp through the output. Can be directly connected to active studio monitor speakers or power amplifier, convenient and quick adjustment by remote control.

> The bridge system which is completely self-developed in cooperation with Celaudio.

> 1. Based on the hardware designed tor music playback, remove all hardware unrelated to music playback and restore the true nature of music.

> 2. Based on CelWare 3.x music playback system, specially designed for music playback 1/0 hardware and software combinations. Hardware design with a Linux kernel optimized for 1/0 depth to achieve better music playback and hardware priority scheduling, minimizing audio data forwarding delay and jitter, and strengthening audio playback capabilities.

> 3. Software control of playback applications, support for closing the useless bridge system, maximize the efficiency of the system music playback.

> XMOS USB adopts XU216 from XMOS, which supports PCM768k DSD512 MQA full decoding.

> Independent voltage stabilization, multi-stage filtering, left-right separation, non-interference.
