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-32 network audio module, it seamlessly supports the AES67 protocol, enabling interoperability with all AES67 network devices. It provides a 28×28 AES67 network channel, offering ultra-low latency, stability, and high-quality audio networking. The DMX232 combines the auto mixier and DSP processor into one unit, reducing system complexity, saving on the number of devices in the network, and budget.

DIGISYN LINK3 GUI Controller
Utilize the DIGISYN LINK 3 free control software to achieve a combination of DSP, audio routing, and online monitoring.
PoE and DC Dual power
DMX232 supports PoE-af standard provides 15W power supply and also DC 12V / 1.5A.
Universal 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.
