Dual Network Bridge Format Converter with up to 64 Bidirectional Channels and Asynchronous Sample Rate Conversion


DN9652 provides a multichannel interface between two third party digital audio networks and point-to-point interfaces. The 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, DN9652 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.
