Due to the price increase of chips, MD1 currently only has the function of U disk playback.
Zishan MD1 is a palm-sized HIFI digital turntable, which can be connected to U disk, with coaxial (output) optical digital signal (output), RCA (output) and 3.5 headphone port (output) analog signal output.
XX:"Please blow your product"
Zishan: "Okay"
1. Compatible with most music formats and U disk file systems in the market
APE, FLAC, WAV, MP3, M4A, WMA, AIFF, AAC, DSF, DFF, ISO, CUE, even multi-channel DTS5.1, etc.
Parse CUE and ISO in seconds.
PCM up to 384k 32bit
DSD hard solution up to DSD256
Support U disk common file system such as NTFS, EXFAT, FAT32, support multi-partition.
2. Complete interface and function and mini size.
With LCD, five-way button, coaxial, optical, RCA, 3.5 headphone port lineout
Can be connected to U disk, support multiple partitions, support multiple file systems NTFS, EXFAT, FAT32
The volume is only 28*84*80. It is a good solution for your home HIFI, car, notebook USB sound card, square dance, etc.
3. NO PLL and ALL Signal comes from CPLD
Zishan adheres to the dual crystal oscillator + CPLD I2S solution. All signals come from CPLD and there is no frequency multiplier phase-locked loop, and the audio crystal oscillator is divided by CPLD until the DAC.
The CPLD takes over the I2S of the main control and Bluetooth, and simultaneously synthesizes the SPDIF signal output in real time.
4. Boost+N LDO design independent of input power
The host only needs a TYPE C data cable to power the whole machine. The BOOST+N LDO design is independent of the input power supply, regardless of the quality of the input power supply, even if the power supply of the shanzhai charging head will not play a big role in the player Influence. But it is recommended to use at least 5V 500mA charging head.
And it provides a voltage of up to 13V and a total of 26V for the op amp, which is suitable for most of the op amps in the market that require high voltage.
5. Single ES9038Q2M
The single ES9038K2M configuration includes an ES9038Q2M chip. Although it is a single DAC chip, its abnormal indicators and the price in the early 300s are extremely cost-effective. At the same time, a plug-in op amp socket is provided for buyers to replace their favorite op amps. .Currently standard op amp LM4562.
7. Simplest DAC->LPF design
Thanks to the dual power supply design, the whole machine does not have a coupling capacitor, and the DAC is connected to the necessary LPF straight out, providing a standard 2Vrms level.
The physical relay suppresses the popping sound of the switch machine, without any audio switch or mute tube.
Multiple incense burners and multiple ghosts, I believe that the simplest design can play most of the level of DAC.
8. Coaxial support DoP
Simply put, it means that the DSD signal is transmitted through the coaxial cable. But at the same time, the decoder needs to support the DoP function. If the decoder DAC in your hand is ES9038 or mojo and other DoP-supporting decoders, when using coaxial fiber to connect to MD1 for playback Real DSD signal transmission and playback can be realized when DSD music is played.
9. Comes with a cute (on the mountain) remote
Equipped with a cute (on the mountain) remote control, it is convenient for Ge You to remotely cut songs while lying down.

XX: "Hey, stop. I said that your product is too dusty after listening to it for too long, so I want you to blow it up"
Zishan: "..."
