ZS-MD1 HiFi DSD Digital Player CSR8675 Bluetooth 5.0 DAC Support 384K 32Bit DSD256 (Dual CS43198)

Description:

It is a palm-sized HIFI digital player, comes with Bluetooth 5.0 CSR8675 (one-way input), can be connected to a USB disk. It supports coaxial, optical fiber, RCA, 3.5 headphones, analog signal outputs.

Features:
1. Compatible with most music formats and U disk file systems on the market.
- For APE, FLAC, WAV, MP3, M4A, WMA, AIFF, AAC, DSF, DFF, ISO, CUE, even multi-channel DTS5.1, etc.
- Analyze CUE and ISO in seconds.
- PCM up to 384k 32bit
- DSD hard decoding up to DSD256
- Support U disk common file systems such as NTFS, EXFAT, FAT32, and support multiple partitions.

2. Complete interfaces and functions and mini size.
- With LCD, five-way button, coaxial, optical fiber, RCA, 3.5 headphone jack lineout
- Can connect to U disk, support multiple partitions, support multiple file systems NTFS, EXFAT, FAT32
- Can be connected to mobile phone Bluetooth, support for APTX-HD and LDAC at the same time
- Connected to USB, used as a USB DAC.
- Compact size 28*84*80mm. It is a good solution for your home HIFI, car, laptop USB sound card, square dance, etc.

3. NO PLL and ALL Signal comes from CPLD.
- Dual crystal oscillators + CPLD I2S solution. All signals come from CPLD and there is no frequency multiplication phase-locked loop. Audio crystal oscillator is divided by CPLD until the DAC.
- CPLD takes over the main control and Bluetooth I2S, and at the same time synthesizes SPDIF signal output in real time.

4. BOOST+N LDO design independent of input power supply.
- Only a TYPE C data cable is needed to power the host. Adopting BOOST+NLDO design that has nothing to do with input power supply, charging head power supply will not have a big impact on the player. It is recommended to use at least 5V 500mA charging head.
- It also provides operational amplifiers with a voltage of up to ±13V and a total of 26V, which is suitable for most operational amplifiers in the market that require high-voltage performance.

5. Deeply customized CSR8675.
- Realize slave mode work of Bluetooth CSR8675.
- There are many products using Bluetooth CSR8675 on the market, but CSR8675 has two fatal problems. One is that it does not provide I2S MCLK signals. The other is that its 24M crystal oscillator is used in addition to frequency multiplication for BT 2.4G band use, but also divides 44.1k 48k. 96k comes out to I2S, and non-integer frequency division, CSR8675 does not have fractional frequency division, you can imagine how bad the quality of I2S that comes with CSR8675, even the frequency is not accurate. For the first point, most of the solutions on the market are used DACs that do not require MCLK such as ES9038K2M or PCM5102. For the second point, some manufacturers use Bluetooth SPDIF signals and then use DIR9001 chips to convert I2S, which are better solutions.
- Our perfect solution is: CPLD provides I2S signal to Bluetooth, Bluetooth follows this I2S signal, only responsible for spitting data, not generating clock signal. It is really implemented on ZS-MD1.
- Now the Bluetooth of ZS-MD1 works in slave mode. When connecting to a mobile phone for APTX-HD or LDAC, we can safely say that it basically meets the definition of HIFI.

6. Optional DAC configurations: One ES9038Q2M, Dual AK4493EQ, Dual CS43198.
- One ES9038K2M: Contains an ES9038Q2M chip. Excellent indicators, very cost-effective. At the same time, a plug-in op amp socket is provided for buyers to replace their favorite op amp. Current op amp is LM4562.
- Dual AK4493EQ: Contains two AK4493EQ chips, one AK4493EQ per channel, which effectively reduces crosstalk and improves separation. At the same time, a plug-in op amp socket is provided for buyers to replace their favorite op amp. Current op amp is LM4562.
- Dual CS43198: Contains two CS43198 chips, one CS43198 per channel. The NOS filter function of CS43198 is opened to reduce modern oversampling technology. Good quality of I2S coupled with CS43198 NOS will meet your nostalgic taste. At the same time, a plug-in op amp socket is provided for buyers to replace their favorite op amp. Current op amp is LM4562.

7. The simplest DAC->LPF design.
- Thanks to dual power supply design, the whole machine does not have a coupling capacitor, and LPF needs to be connected directly after the DAC, providing a standard 2Vrms level.
- Physical relay suppresses the cracking sound when turn it on/off, and there is no audio switch or mute tube.
- The simplest design can play most of DAC level.

8. Coaxial supports DoP.
DSD signal is transmitted through the coaxial cable. But at the same time, you need a decoder to support DoP function. If the decoder DAC in your hand is a DoP-supporting for decoder such as ES9038 or mojo. Using a coaxial fiber to connect to the ZS-MD1 to play DSD music , You can realize the real DSD signal transmission and playing.

9. Support USB DAC function.
- It can be connected to a computer or mobile phone as a USB sound card. It is used to improve the sound quality of your computer or mobile phone.

10. Comes with a cute remote controller.
- With a remote controller, it is convenient to remotely select songs while lying down.
