Raspberry pi Coaxial HIFI Sound Card I2S DSD Digital Broadcasting
R19 Raspberry Pi Digital Output Board Introduction
1. Professional SPDIF digital processing solution, coaxial support output 384K/DOP128, seckill often
See AK4118, WM8804 program
2. Local dual audio clock synchronization, avoid using PLL to generate clock and cause cold sound
3. The Raspberry Pi uses IIS to input and play music, the listening experience is smooth, real and natural, and never used
The feeling of pause that is difficult to detect when playing in USB mode
4. Use the general version VOLUMIO, MoodeAudio
VOLUMIO official version can support 44.1-192KHZ DSD64 original code output
MoodeAudio official version can support 44.1-384KHZ DSD64-DSD128 original code output
5. No need to set output resampling, just turn it off by default, truly original code lossless output
6. Adopts DS8921, a dedicated driver chip for coaxial, which is recognized as good sound
7. Use HDMI interface to output IIS signal, with MCLK output, multiple output modes can be set
And MCLK clock frequency, convenient to connect to most high-end DAC decoders on the market

Parameter test description:
Raspberry Pi 4B (version 1.2) install optimized version of MoodeAudio640, broadcast
The music file on the USB flash drive is measured, and there will be differences under other conditions, such as: MoodeAudio7. 01Official
The version can support PCM384KHz/DSD128 (original code)
powered by
The 5V power supply of the board is directly connected to the 40P interface of the Raspberry Pi. There are two ways to supply power as follows
a. Directly use the micro usb to power the Raspberry Pi
