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.

Universal AoIP Network Audio Mixer

The DMX232 can receive and process up to 28 multicast streams from diverse audio devices, breaking down compatibility barriers across systems. Equipped with ​gain sharing Mixing, it intelligently manages microphone channels by attenuating inactive inputs to reduce noise and echo—ideal for conferences and speeches. Its ​Gating Mixing​ mode allows users to set level thresholds for each channel, minimizing ambient noise and enhancing dynamics, making it suited for live sound and broadcasting.
