Klark Teknik DN9680

The Klark Teknik DN9680 is a professional-grade 8-port AES50 extender and multiplexer designed to overcome typical 100 m copper cable limitations. It enables high-channel-count, low-latency audio networks over long distances—ideal for FOH, broadcast, or distributed digital-snake applications.

Key Features

• Extends up to 8 AES50 links (192 bidirectional channels at 96 kHz) over a single snake cable

• Supports up to 1 km via single-mode fibre, or 100 m via CAT5 copper

• Acts as a bidirectional multiplexer/demultiplexer for transparent channel routing

• Ultra-low latency: ~250 μs propagation delay per snake pair

• Embedded AES50-grade TCXO clock (1 ppm) with selectable sync source

• Configurable via front panel or onboard web server using Ethernet control

• Rugged 1U rack chassis with EtherCON and opticalCON connectors

• Universal 100–240 VAC PSU with optional redundant power supply
