MP-DX HiFi Digital Audio Player Dual ES9068AS DAC + Digital Play Board for Raspberry Pi 4B + for SanDisk 64GB Volumio System)

Description:
- On the basis of the widely acclaimed MP-D1 and MP-D2 decoders, MP-DX has taken many years to comprehensively upgrade and optimize the circuit tuning, solving the common problems of digital players and decoders in the market, such as strong digital feel and lack of analog music feel, and creating a beautiful sound and comprehensive digital playback decoding all-in-one machine.

- MP-DX features Raspberry Pi 4B as the core digital play board, providing a free and open lossless music play experience. Unlimited free software upgrade, supporting local USB hard drives and NAS file playback. Supports network audio push protocols for ROON, for APPLE Music airplay, and for Logitech Squeezelite, and can use open-source player systems for VOLUMIO, for RoPieee, and for Mood.

- Built in professional designed electricity supply filter board to filter out electricity supply noise interference and make the background cleaner. Adopting customized dual ring high-power transformers, with independent power supply for both analog and digital circuits, greatly reducing interference. The transformers are all made of imported high-quality A-grade non fracture gray iron core, made of genuine materials.

- Adopting for Qualcomm QCC5125 Bluetooth 5.0 protocol audio receiving module, supporting for SBC/AAC/APTX/APTX-LL/APTX-HD/LDAC Bluetooth audio. Connect wirelessly to your phone, tablet PC, or computer through Bluetooth for a convenient playback and listening experience, as well as near CD level quality enjoyment.

- Dual DAC plug-in modular design, open upgrade architecture.

- The coaxial fiber input adopts for TI transceiver chip, providing 50ps extremely low time base error performance, fully demonstrating the best level of front-end CD turntable and independent digital player.

- The USB input adopts for Amanero ARM+CPLD scheme, which is generally considered more musical by users compared to XMOS.

- Using a grouped hierarchical linear regulated power supply structure, using for ADI and for ST micro-volt level ultra-low ripple LDO, providing ultra pure logistics power supply support for digital circuit chips and decoding chips.

- Adopting American military low-temperature floating enthusiasts resistors for VISHAY, for WIMA, for WE, for Panasonic, for Rubycon and other enthusiasts capacitors, we strive to provide users with the best listening experience and long-term quality assurance.

- The MUC control unit supports wireless WIFI firmware upgrades, allowing users to easily and freely upgrade firmware to support more new DAC modules and functions in the future without returning to the factory. You can enjoy the different listening experiences brought by various decoding chip modules without the need to switch machines.

- The panel is equipped with an OLED screen, allowing users to adjust the output volume, select different inputs, and select different digital filtering methods. It have memory functions, and when it is turned off, the original settings will not be lost. You can choose different digital filters and customize your favorite voice.

- Differential fully balanced electronic tube analog output circuit, with no operational amplifier and negative feedback design, the sound is natural and pure, with a strong sense of simulated air. Immersed in a grand stereo field, you can enjoy a different listening experience.

- The output coupling capacitor is the final level through which audio signals pass, and its status is no less than that of an electronic tube. Replacing different output coupling capacitors can obtain different analytical power and timbre performance. MP-DX provides quick terminal disassembly, allowing users to easily replace different output coupling capacitors without the need for welding skills. The standard configuration is the silver foot polypropylene non-inductive enthusiasts capacitor for OHVL. Note: RCA output only needs to be replaced with the first and third capacitors from the left.

- The digital board, MCU board, and decoding motherboard adopt a fully digital isolation architecture to fully isolate front-end digital noise and avoid interference with pure DAC and analog circuits, resulting in a cleaner music background.

- The MP-DX adopts for ACCUSIL ICON AS318 high-precision dual frequency clock. At the same time, it also provides an external clock input SMA interface, which can connect to suitable frequency constant temperature clocks and rubidium atomic clocks.

- Supports infrared remote control volume, input selection, mute, and screen rest.
