The Klark Teknik KT-DN9620-UL is a specialized professional audio networking device designed to extend the range and flexibility of AES50 SuperMAC audio networks. Its primary function is to act as both a signal extender and a multiplexer, enabling the transmission of high-channel-count, low-latency digital audio over remarkably long distances using standard optical fiber infrastructure. This device effectively bridges the gap between digital mixing consoles and remote stageboxes or other networked devices when copper cable runs are insufficient. By converting the electrical AES50 signal to an optical format, it can reliably transmit up to 96 bidirectional audio channels over distances up to 500 meters, eliminating concerns about signal degradation, ground loops, and electromagnetic interference that plague long copper runs.

The unit features two independent optical ports, allowing it to function in various network topologies such as point-to-point links or as a node within a daisy-chained system. This dual-port design provides flexibility for system designers to create redundant paths or to connect multiple remote locations back to a central hub. The KT-DN9620-UL handles all sample rate conversion and clock synchronization transparently, ensuring sample-accurate audio transmission across the extended network. It is engineered for absolute reliability in mission-critical live sound and broadcast environments, where signal integrity and zero dropouts are non-negotiable requirements for performances or live broadcasts.

Housed in a sturdy 1U rack-mount metal chassis, the device is built for both permanent installation and touring use. It features clear status indicators for power, network synchronization, and signal integrity on both its electrical and optical sides. Operation is typically plug-and-play, requiring minimal configuration once the physical fiber connections are established. The KT-DN9620-UL is an essential infrastructure component for large-scale audio systems, enabling engineers to place mixing consoles at ideal listening positions in large venues while keeping digital stageboxes close to the performance area, all while maintaining the pristine quality and tight synchronization of a direct digital connection.
