This product is a finished board, using the latest audio DAC ES9038 Q2M as the core design, comprehensive in-depth software control optimization, PCM DSD switching without popping, 3 groups of inputs can be connected at the same time, and the jumper can switch smoothly
The characteristics of the product are as follows:
1. Onboard single-chip MCU, used as a pure IIS/DSD input DAC board
2. Support coaxial and optical input, support PCM44.1Khz-192Khz/DSD64 hard solution
3.The onboard provides a volume control interface, and the volume control can be achieved by connecting a single-linked potentiometer of about 10KR.
4. Compared with the previous generation ES9028Q2M, ES9038Q2M is more complete, with thicker sound, and directly supports coaxial fiber DOP,
DSD direct solution, 129dB DNR -120dB THD+N is quite excellent.
5. The default 5532DD op amp comes with the board, and the original Zhengling op amp is used to facilitate customers to upgrade the op amp with a fever.
6. Use imported high-precision active crystal oscillator
7. Use high-quality gold-plated RCA socket, headphone output interface
8. Onboard signal LOCK indicator and DSD signal indicator
Input support:
Coaxial: PCM44.1K-192K 24BIT / DOP DSD64
Fiber: PCM44.1K-192K 24BIT / DOP DSD64
IIS/DSD: PCM44.1K-384K 24B-32BIT / DSD64, DSD128, DSD256
IIS/DSD pin definition:
Output: dual-channel single-ended RCA output, 3.5 headphone monitor output
Power supply: Regulated DC voltage dual 12-15V or Regulated DC voltage single 12-15V
*It is recommended to use dual 15V power supply to achieve the best effect of the board.
Too low power supply voltage will affect the output, too high power supply voltage will lead to increased voltage regulation and heat generation
Working current:
Standard version:
1. Dual 15V mode: +15V about 120MA, -15V about 10MA
2. Single 15V mode: about 120MA
Power supply description: The board is shipped with dual 15V power supply mode by default. To change the power supply mode, you need to set the corresponding jumper:
Jumper setting description: O=connect; X=disconnect
Input settings Digital filter settings
Jumper setting instructions: 1. O=connect; X=disconnect,
