MD3 ES9038Q2M (JRC2068) Portable Vehicle-mounted Digital Turntable HiFi DSD Lossless Audio Decoder Bluetooth LDAC 0.96-inch OLED

Features:
Compatible with most music formats and USB file systems on the market:
- It is compatible with APE, FLAC, WAV, MP3, M4A, WMA, AIFF, AAC, DSF, DFF, ISO, CUE, and even multi-channel DTS5.1. Supports multiple partitions, file systems NTFS, EXFAT, FAT32, and no capacity limit for hard drives and USB drives, second resolution of CUE and ISO.
- PCM up to 384k 32bit
- DSD hard decoding up to DSD256
- Supports common file systems on USB drives such as NTFS, EXFAT, FAT32, and supports multiple partitions.

Adopting self-developed Bluetooth Module:
- Supporting domestic production, using the self-developed ESP32 Bluetooth module, Bluetooth version 4.2, and supporting SBC, APTX, APTX-HD, LDAC protocols, with a maximum LDAC protocol of 96k 24b.

Supports USB DAC Function:
- Supports UAC2.0 protocol, connects to Windows 10 and Windows 11 systems without the need for drivers, and can achieve up to PCM 348K 32b and DSD128 playback.

NO PLL and ALL Signal comes from CPLD:
- Dual crystal oscillator + CPLD I2S solution. All signals come from CPLD and there is no frequency doubling phase-locked loop. The audio crystal oscillator is divided by CPLD until DAC.
- CPLD takes over the I2S of the main control and Bluetooth, while synthesizing SPDIF signal output in real-time.

Single ES9038Q2M:
- The single ES9038K2M configuration includes a built-in ES9038Q2M chip. Although it is a single DAC chip, its abnormal specifications and a chip price make it extremely cost-effective. At the same time, it provides a plug-in operational amplifier socket for buyers to replace their favorite operational amplifier.

Minimalist DAC -> LPF Design:
- Benefit by the dual power supply design, the entire machine does not have a coupling capacitor, and the DAC is connected to the necessary LPF output, providing a standard 2Vrms level.
- The physical relay suppresses on/off noise, without any audio switching switch or mute tube.

Coaxial Support for DoP:
- DSD signals are transmitted through coaxial lines. However, at the same time, the decoder needs to support DoP function. If your decoder DAC is ES9038, for Mojo or other decoders that support DoP, you can achieve true DSD signal transmission and playback when using coaxial fiber to connect to MD3 and play DSD music.

Equipped with a Remote Control:
- Equipped with a remote control, it is convenient to remotely switch songs while lying down. All functions can also be operated through the five way buttons on the front panel of the remote control.
