GUSTARD DAC-X20pro ES9028PRO XMOS Geshide dual solutions support DSD DOP 384K

Geshide is the first batch of domestic development and application of ESS series decoding chip and XMOS high performance USB audio integration products company. In 2012 2014, the introduction of high performance DAC-X10 decoder based on ES9018 DAC-X12, launched in 2015 and launched the double ES9018 chip DAC-X20 series of products are welcome and praise of the majority of the fancier. But the company does not stop here, has been carried out on the development and exploration of ESS chips, and continue to communicate with the ESS official technical. Recently the United States ESS company launched ES9028PRO, the decoder chip upgrade chip ES9018, the signal-to-noise ratio is up to 129dB, the distortion rate of -120dB compared to the widely used ES9018K2M (signal-to-noise ratio 127dB, distortion rate -120dB) has been greatly improved. We also introduced the first time X20 decoder upgrade version --X20pro. X20pro is based on the two ES9028PRO decoder chip, power supply circuit digilogue collocation matrix separation, the digital part is the first use of adaptive master clock technology, and uses its own application for a separate line in the simulation part, perfect playback of the audio. The low frequency quantity feeling and texture of both, if honest and accurate, high transparent, elegant, and has a deep sound field with excellent resolution. X20pro whether it is functional, performance or sound quality than the previous generation X20 has a lot of improvement.

The technical characteristics of X20pro Geshide: The left and right channels each with a ESS company\'s top ES9028PRO chip for decoding, completely independent power supply, independent grounding, to obtain the best performance, not interfere with each other;

-China\'s first use of adaptive master clock technology and asynchronous master clock technology, the two modes of choice, perfect corresponding to different signal sources;
CPLD programmable logic chip, digital integrated circuit to construct the logical function, clock management, 2nd PLL, DOP, PCM/DSD plastic digital demodulation depop switch exclusive technology, has laid a solid foundation for the excellent sound quality;

Digital simulation of the production of a customized 50W dedicated ring transformer, completely independent of the power does not interfere with each other; Native full balance architecture, without any conversion, complete four way output; Analog LPF circuit using the independent development of discrete lines, carefully adjust the parameters of each level, in order to achieve the best working conditions; -With 0dB, +6dB, +12dB three selectable gain, and supports 0dB~-90dB 90 files of high quality digital volume control, with high quality remote control comes with easy collocation after class, active speaker; Full interface supports DSD hard solution: IIS supports DSD64, DSD128, DSD256, DSD512 hard solution; SPDIF, Optical, AES/EBU support DSD64 hard solution (DOP model); USB supports DSD64, DSD128, DSD256 hard solution; Rich digital filter There are 7 types of PCM: /M-SLOW M-SHARP / L-SHARP / L-SLOW / HYBRID / APODIZING / /BRICKWALL, There are 4 kinds of DSD: 47K/50K/60K/70K; USB using XMOS company\'s USBAUDIO dedicated chip U8 (XU208 and U8 kernel is the same), support for DSD256 PCM384 Screen brightness can be adjusted, no operation after 10 seconds automatic memory, the next boot to keep the last set, the human operator control; All aluminum chassis, surface drawing, all silver (sub white) and all black two colors can be selected; Machine size: wide 380* deep 65MM high 260* (no protruding part); Packing size: long 470* wide 360* high 175MM; Packaging weight: 7KG; International voltage AC100V-240V (manual adjustment); -Frequency response: +/-0.08dB 20Hz-20kHz
Line output: RCA output level single ended 3 0dBFS Vrms, balanced 6 0dBFS Vrms
XLR interface definition: American Standard (1, 2, 3 cold)

Geshide DAC-X20pro:

Rigorous design, reasonable layout, clean and tidy, with solid materials.

Two pieces of ES9028PRO, the left and right channels each use a piece, sound stability and detail rich dynamic enough without interference.

Independent analog board, digital and analog separate design;

Simulation of LPF circuit using its own application for many years a full line of separation. Each discrete device only needs to consider its own performance, so only for this device, a lot of application limitations, it can give full play to the performance of individual components. Because unlike the integrated circuit that can not be separated and change are integrated in the chip, the use of discrete devices is more flexible, can freely adjust the parameters of each level, so as to achieve the best working state, but also because of its stronger development, and is also relatively controllable part for distortion, can give the decoding framework different from can change more sound style.
The disadvantage of discrete devices is that the distribution parameters have great influence on the design and debugging is very difficult, need to have a certain technical experience and a long process of debugging. In the consistency is also relatively weak, so the need for materials is very elegant.

China\'s first use of adaptive master clock technology and asynchronous master clock technology, two kinds of clock mode free switching. CPLD digital integral technology.

The United States ACCUSILICON femtosecond oscillator;

Power supply scheme for discrete multilevel voltage regulator + multilevel filter

Digital simulation of the production of a customized 50W dedicated ring transformer, completely independent of the power supply does not interfere with a steady stream of power for high-quality sound;

Optional USB card
