1. Pure digital output, 24BIT 192KHz high specification is close to the studio standard, the dynamic range of signal-to-noise ratio exceeds 120DB 2. Richer formats, support APE/FLAC/ DIGITAL7.1/DTS, enjoy high bit rate and multi-channel 3. The anti-interference performance of digital transmission is particularly excellent. If it is matched with optical fiber transmission, electromagnetic interference and ground interference can be basically eliminated, and the sound quality can be greatly improved. 4. SNR, dynamic range exceeding: 120db 5.
