The audio D/A and A/D converters are designed as a 1U standard chassis to achieve better integrated applications in computer rooms. One chassis can accommodate two boards at the same time, supporting dual power supply for primary and backup, and allowing for free selection of D/A or A/D boards as needed.
DDA101 is a broadcast grade analog-to-digital converter board, and DAD102 is a broadcast grade analog-to-digital converter board, both of which comply with AES3 (AES3-2009) and GY/T 158-2000 Studio Digital Audio Signal Interface standards. Suitable for use in various studios, control rooms, and transmission stations.
