Ever-Iterating AES67 Devices
The DMX208A is a powerful AES67 network audio matrix that supports communication with other AES67 devices. It enables full-system audio routing, device configuration, real-time monitoring, and DSP management through the All-in-one software. With support for DSP customization and OTA upgrades, it ensures continuous updates and functional optimization of the device.
Now supporting SMPTE ST2110-30
Since July 2025, all devices upgraded to firmware version 3.1.4.67 or later have gained support for user-configurable DSCP QoS priorities, PTP domains (Precision Time Protocol Domain), and multicast port numbers. This enhancement ensures the devices fully meet the stringent requirements of broadcasting network environments for advanced Quality of Service (QoS), precise clock synchronization, and flexible multicast management.
DIGIGYSN LINK-embedded
Equipped with the DL-08D network audio module, it seamlessly supports the AES67 protocol, enabling interoperability with all AES67 network devices. It provides a 4×4 AES67 network channel, offering ultra-low latency, stability, and high-quality audio networking. The DMX208A combines the stage box and DSP processor into one unit, reducing system complexity, saving on the number of devices in the network, and budget.
