Hxmelody HX500 ES9038PRO PCM768KHz 32Bit DSD512 SACD DNLA Digital Turntable Lossless CD Music Player HIFI Streaming Media Player

Features:

FPGA master control, control and decoding are each a motherboard, digital and analog are designed separately to eliminate mutual interference

FPGA control logic adopts synchronous design idea. That is, sampling external signals and reconstructing I2S and DSD timing from the local clock. Unlike traditional CPLDs that only do the simplest gating control, only large-scale FPGAs have enough resources to synchronize all signals. If the description is improper, the harm caused by non-synchronous combinational logic gating is the increase in signal jitter and the misalignment of signal timing, resulting in "metastability", "competition" and "risk" (technical terminology in logic description), which ultimately leads to critical Audio data has an error, which is unacceptable for audiophiles with demanding sound quality.

DSD hardware solution, full interface supports DSD

Only use ES9038PRO as DA conversion (only use the internal digital and analog conversion functions, without using the SPDIF to I2S separation function, DoP protocol, etc., within the ES9038PRO, which is completed by the red core FPGA control board, so that digital and analog are independent of each other

HDMI input supports DSD1024, PCM768K (when I2S or DSD source code is input, we can display the specific sampling rate of the currently input PCM song, the specific specification of the DSD song, this function is unique to the red core)

USB input supports DSD512, PCM384K, automatically analyzes and displays the input song specifications

Built-in compatible Italian USB interface (can be connected to Android phones to output high-quality music through this decoder, mobile phone support is required)

Analog single-ended, native fully balanced (true balanced) output

It adopts a genuine 3.2-inch Tianma HD display with a screen resolution (480 X 320). The display content is simple and generous. The vector font display has higher definition than the traditional display. The screen can be turned off when listening to music at night.

Support remote control and panel volume, filtering, input source switching, all operations are automatically stored and memorized.

Op Amp: A total of 6 single op amps are used, and the delivery is (OPA604 X 4 + LME49710 X 2 or AD797 X 2 or OPA604 X 2)

Upgradeable firmware (firmware: the control program of the decoder itself, when a new function is released, customers can upgrade the system through SD card, or develop new firmware to improve system performance or sound quality, which will be released by the Red Core official uniformly, and customers can upgrade themselves. The upgrade process is simple and quick. Firmware download address: www.hxmelody.com firmware download area)

More reasonable power supply design scheme, strictly control the heating of the whole machine and ES9038PRO (difficulty in the industry), avoid the machine overheating caused by the machine for a long time or the environment temperature is too high to accelerate the aging of internal components, you will never have to listen to songs for a long time Worried about the machine getting hot.

Intelligently analyze the input signal and completely turn off the power of ES9038 when it loses lock and standby, reducing the power consumption of the whole machine

Using 2 imported 25w talema potting transformers, digital and analog independent power supply, enough power to escort the output high-fidelity sound quality

Original ON Semiconductor high-speed high-power low-resistance rectifier tube, up to 8A, low heat. Imported components such as original ELNA, Panasonic FC, Panasonic FJ, AVX tantalum capacitor, Linear Technology, Omron relay, Furukawa plug, femtosecond, etc. are used.

ES9038PRO works asynchronously, and the independent clock crystal adopts imported 100MHz CRYSTEK low-noise femtosecond clock

Abundant input interfaces (coaxial, optical fiber, BNC, AES/EBU, USB, HDMI). When HDMI input, DSD OE signal is not needed, and it is intelligently identified by FPGA internal logic.
