1. Professional SPDIF digital processing solution, coaxial support output 384K/DOP128, seckill often See AK418, WM8804 program 2. Local dual audio clock synchronization, avoid using PLL to generate clock and cause cold sound 3. for uses IIS to input and , 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 VOLUMI0 official version can support 44.1-192 KHZ DSD64 original code output Moodeaudio official version can support 44.1-384 KHZ DSD64-DSD128 original code output 5. No need to set output resampling, just turn it off by default, truly original code lossless output<br><br>Adopts DS8921, a dedicated driver chip for coaxial, which is recognized as good sound Using 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 decoders on the market for digital output board specifications Digital output Coaxial: PCM44.1KHz-384KHz/24Bit DSD DSD64/128 () Fiber: PCM44.1KHz-192KHz/24Bit DSD DSD64() IIS: PCM 44.1KHz-384KHz/32Bit DSD DSD64/128/256/512(Native DSD Parameter test description for Raspberry pi4B (version 1.2) install the optimized version of Moodeaudio640, broadcast Measured with the music file of the USB flash drive, there be differences under other conditions, for example: for Moodeaudio7.01 official The version can support PCM384KHz/DSD128 (original code) Colour:Black Material:plastic<br><br>Package Contents: 1 x Digital audio output board 1 set x accessories<br><br>Only the above package content, other products are not included.
