The new DN9630 AES50 to USB 2.0 Converter, with up to 48 Bidirectional Channels, simplifies the connection of computers to AES50 audio networks to provide simultaneous multi-channel computer audio recording and playback, making it ideal for use with MIDAS digital consoles and other AES50 equipped products. The single USB 2.0 interface connects directly to a Windows* PC or Apple* Mac and features a very high channel count, offering up to 48 bidirectional channels at 48 kHz and 24 bidirectional channels at 96 kHz sample rates.

Klark Teknik DN9630 400pxDigital Audio Networking

Our SuperMAC (AES50 Compliant) digital audio networking technology simultaneously provides: high channel counts; ultra low and deterministic latencies; sample synchronous and phase-aligned networked clock distribution; error detection and correction along with network redundancy.

Ethernet Control Data Support

DN9630 provides a separate RJ-45 port which serves as an external interface for the bidirectional AES50 auxiliary data channel. This data link allows remote control and metering of connected AES50 devices via standard Ethernet communication.

Dual Sample Rate Support

A dedicated slide switch is provided for either 48 or 96 kHz sample rates, allowing the DN9630 to work with either AES50 network’s incoming source clock for flawless synchronization.


DN9630 utilises dedicated audio software drivers for Windows* PC operation (free of charge download at, and supports the high channel counts offered via USB 2.0. Apple* Mac OS X provides native Core Audio driver support for the DN9630.
