The DN9620 is a 1U, half-rack width AES50 extender, which takes two Cat 5 AES50 streams and multiplexes up to 96 bi-directional channels of 24-bit audio via a single fibre-optic cable for up to 500m or a single Cat 5e cable for 100m. The unit is fitted with an integrated auto-ranging power supply, and uses all genuine Neutrik etherCON and opticalCON connectors for maximum reliability.he benefits of combining audio, control and clock into one single network are simplified connectivity, reduced set-up times and lower investment in cabling infrastructure.
