The DN9620 AES50 Extender from Klark Teknik is a 1U, half-rack width AES50 extender, which takes 2 Cat 5e AES50 streams and multiplexes up to 96 bi-directional channels of 24-bit audio via a single fiber-optic cable for up to 1640' (500m) or a single Cat 5e cable for 328' (100m). Both formats feature low latency of just 0.105ms input to output. The DN9620 operates at either 96 or 48 kHz sample rates and offers the user multiple clocking options. The unit is fitted with an integrated auto-ranging power supply and uses Neutrik etherCON and opticalCON connectors for maximum reliability.
The DN9620 Extender overcomes the inherent limitations of Cat 5e cabling, which limits cable runs between AES50 devices to 100m (330'). The DN9620 will operate as an optical snake system for any MIDAS, or other digital console which uses the AES50 protocol, and provide long-haul, optical connectivity between I/O units, as well as extending the deployment possibilities of I/O, recording, and other AES50 hardware throughout a building or campus.
AES50 is an open-architecture digital audio transport protocol which benefits from extremely low latency (<70 us.), robust feed-forward error connection, and advanced system clocking. AES50 connections carry digital audio and control data bi-directionally down a single Cat 5e cable. The benefits of combining audio, control, and clock into a single network are simplified connectivity, reduced set-up times, and lower investment in cabling infrastructure.
