The DN9620 provides a high channel count solution to the 100 metre limitation that Ethernet and CAT5 cabling imposes on the physical size of AES50 networks. A pair of DN9620 units allow up to two AES50 connections (48 or 96 bidirectional channels channels at 96 kHz or 48 kHz sample rates respectively) to be extended by up to 500 metres via multimode optical fibre or 100 metres via CAT5 copper cable, simplifying long haul cable connections due to the use of a single bidirectional snake cable.
DN9620 acts as a bidirectional multiplexer and demultiplexer, and combines the two incoming AES50 streams into the outgoing snake connection, and simultaneously also takes the incoming snake connection and unbundles the two AES50 streams and routes them to the corresponding AES50 ports. A snake system consisting of a pair of DN9620 units routes the incoming AES50 streams to the outgoing streams on a one-to-one port basis, so that the snake is transparent in use, only incurring a small propagation delay of 270 microseconds.
DN9620 is supplied in pairs, and a 19″ rackmount adapter bracket is also included.
