Description
DN9650
DN9650 provides a multichannel interface between AES50 networks and third party digital audio networks and point-to-point interfaces. The AES50 and third party interfaces operate in separate clock domains and are connected by a bidirectional asynchronous sample rate converter (ASRC). This unique KLARK TEKNIK technology allows the interfacing of up to 64 bidirectional channels between the two independently clocked domains, which can also operate at different sample rates. Currently supporting MADI and Audinate Dante via the KLARK TEKNIK KT-MADI And KT-DANTE64 network modules, DN9650 is future-proofed in the evolving world of digital audio networking technology by being able to support new and emerging protocols via its industry-standard expansion slot, which is compatible with the Cirrus CM-1* format.
The DN9650 allows MIDAS PRO Series digital consoles and MIDAS digital I/O hardware and other 96 kHz-enabled AES50 devices to interface to multichannel MADI and Dante connections, simply and reliably.
Asynchronous Sample Rate Converter
The multichannel bidirectional Asynchronous Sample Rate Converter (ASRC) allows the AES50 and third party domains to function independently, however in instances where the two networks need to be synchronised, the ASRC features a bypass facility so that the third party network domain can be directly clocked from the AES50 domain.
Additionally, when the two domains are operating independently, a clock failure or loss of synchronisation in one domain will not necessarily affect the operation of the other. Very often in dual-redundant systems it is desirable to propagate a clock failure in one domain across to the other, so that the failure can be recognised and switchover to the redundant network can be initiated. DN9650 features a user-configurable bidirectional output clock inhibit feature that will stop the output clock if the incoming clock synchronisation fails.
Internal Web Server
DN9650 features an on-board web server that allows platform-independent configuration using a web browser application. The need for separate control applications and support for multiple operating system versions is eliminated with this approach, which allows simple user selection of network module and DN9650 settings, including AES50 and third party network domain sample rates, clock synchronisation for both domains and the ASRC bypass and bidirectional output clock inhibit functions.
