Usage Tips:1. Pure digital output, 24BIT 192KHz high specification is close to the studio standard, the dynamic range of signal-to-noise ratio exceeds 120DB2. Richer formats, support APE/FLAC/DOLBY DIGITAL7.1/DTS, enjoy high bit rate and multi-channel3. The anti-interference performance of digital mission is particularly excellent. If it is matched with optical fiber mission, electromagnetic interference and ground interference can be basically eliminated, and the sound quality can be greatly improved.4. SNR, dynamic range exceeding: 120db5.
