1. Using original ES9038Q2M JRC5532
2. Using high-precision active crystal oscillator, black diamond/ruby electrolytic capacitor
3. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine
4. The RCA lotus seat is gold-plated and uses Foxconn headphone jack
5. Any choice of single power supply/dual power supply (power supply is DC! The default shipment is single power supply!)
Note: In the picture Power selection, the resistance welding is on the left position for dual power supply, the welding on the right position is for single power supply, and the default welding position is on the right position, that is, single power supply, no matter single power supply or dual power supply, it is DC power supply.
special function:
1. Press the button to switch the input mode (coaxial, optical, I2S)
2. Support buttons and potentiometer to adjust the volume (dip switch to select the volume adjustment method)
3. LED indicator shows input mode (PCM/OPT/COA), signal indicator (LOCK), DSD indicator output (DSD)
Button function description:
1. MODE button: short press to mute, long press to switch input mode
2. VOL-button: short press and long press will decrease the volume
3. VOL+ button: short press and long press are volume up
Basic parameters:
Voltage: DC 9-15V (standard DC5.5*2.1 seat)
PCB size: 75*90MM
Output terminal: RCA+3.5 terminal, can be directly connected to power amplifier, amp, earphone
Input support:
I2S/DSD: 32bit 384k/DSD64, DSD128, DSD256
Coaxial fiber: 44.1k-192k/DSD64
Pin description:
The front of the board interface is facing up, from top to bottom: GND, 5V output (reserved for power supply to the daughter card behind, such as our bluetooth daughter card), LRCK, BCLK, DATA
Main selling point:
1: Perfect and seamless use with the interface, PCM DSD switching is flawless.
2: AC and DC power supply, easy to use
3: ES9038Q2M parameters are relatively complete, 129dB DNR -120dB THD+N is not comparable to the old chip.
4: The board volume is 75X90 for easy installation
Because the MCLK of ES9038Q2M is an independent clock of 100M, it is very convenient to only need to input DATA BCK LRCK. Polishing CD DVD old decoding works well. Delicate and round, the extension is very good.
Frequently Asked Questions:
1. Why does I2S only have 3 wires, isn`t there 4 wires normally?
Answer: ES9038Q2M integrates MCLK, so there is no need for a separate MCLK master clock.
2. Can it be used with Raspberry Pi?
A: Raspberry Pi is supported.
