Klark Teknik DN9650 - AES50 Network Bridge Format Converter with 64 Bidirectional Channels and Asynchronous Sample Rate Conversion in Silver Finish

The Klark Teknik DN9650 is a powerful AES50 network bridge and format converter, offering seamless integration between AES50 networks and third-party digital audio systems. Designed to handle up to 64 bidirectional channels of audio at either 48 kHz or 96 kHz sample rates, the DN9650 serves as a flexible and reliable solution for connecting Midas digital consoles and other AES50-equipped devices with MADI, Dante, or other audio network protocols. This device is crucial for live sound environments, studio recording, and broadcast applications where different digital audio formats and sample rates need to be bridged effectively and efficiently.

At the core of the DN9650 is its innovative Asynchronous Sample Rate Converter (ASRC) that allows two independently clocked domains (AES50 and third-party digital networks) to operate without the need for synchronized clocks. This makes it possible to interface different systems running at different sample rates while maintaining high-quality audio performance. The ASRC can be bypassed when needed, allowing the third-party network domain to synchronize directly with the AES50 clock for flawless integration. The unit supports high channel counts, with 64 bidirectional channels at 48 kHz or 32 channels at 96 kHz, making it ideal for complex setups requiring substantial audio throughput.

The DN9650 also features robust clocking capabilities, with a highly accurate internal "AES Grade 1" temperature-compensated word clock oscillator, ensuring precise synchronization of the audio system. This reference clock has a stability of 1 part-per-million (ppm), providing superior clocking accuracy and reducing jitter and digital clocking errors. The unit can synchronize both the AES50 and third-party network domains to either the AES50 internal clock, an external AES50 clock, the word clock input, or a black burst video sync signal. The black burst video sync input supports standard and high-definition formats, ensuring compatibility with both PAL, SECAM, and NTSC formats, as well as high-definition 720P, 1080P, and 1080i formats for video synchronization in live or broadcast settings.

For added flexibility, the DN9650 features an onboard web server that allows platform-independent configuration via a web browser. This eliminates the need for dedicated control applications and ensures compatibility with multiple operating systems, simplifying the process of adjusting the device's settings. From the web interface, users can configure AES50 and third-party network sample rates, clock synchronization, ASRC bypass settings, and the bidirectional output clock inhibit feature, which is particularly useful in redundant network systems. The status LEDs and the alphanumeric LCD display provide clear, real-time feedback on AES50 and network synchronization, making it easy to monitor the device's performance even from a distance.

Built to withstand the demands of live concert touring, the DN9650 is housed in a rugged 1U steel rackmount chassis. Premium Neutrik etherCON connectors are used for the AES50 ports, ensuring secure and reliable connections even in the most demanding environments. Additionally, the unit features a universal auto-ranging switch-mode power supply, making it compatible with power systems worldwide. The DN9650 offers an essential, high-performance solution for professionals looking to bridge AES50 networks with other digital audio systems while maintaining exceptional audio quality and clock synchronization.
