dMix 128 – Network Audio & ST 2110 FAQ

Technical reference for broadcast, live sound, and system-integration clients using dMix 128 in AES67 / ST 2110 networks and mixed-vendor audio-over-IP environments.

The dMix 128 supports AES67 natively, including full PTPv2 synchronization and up to 48 bidirectional network-audio streams. Support for ST 2110-30 (PCM audio) is currently in development and is scheduled for release within the next 4 months.

Supported now

Coming soon

AES67 is native on the main network ports. ST 2110-30 will be native as part of a firmware update (no option card required). ST 2110-31 is not implemented and currently not planned.

Sample rates

The dMix 128 uses PTPv2 following the AES67 / SMPTE-2059 profile with BMCA master election. It can operate as a PTP follower or as a PTP master when configured accordingly.

Current capabilities

The dMix 128 supports full AES67 interoperability with Dante, Q-SYS, RAVENNA, and 2110-30 equipment that supports AES67 mode. It uses SDP-based stream description and standard multicast subscription control.

Not yet implemented

Real-world deployments

The dMix 128 operates natively at 96 kHz and maintains extremely low end-to-end latency even in complex DSP workflows.

96 kHz operation (native DSP rate)

Analog → AD → Network → DSP → DA → Analog ≈ 0.7 ms

48 kHz operation

Upsampling/downsampling adds conversion stages ≈ 1.3 ms

DSP impact

All channel processing occurs at 96 kHz, maintaining extremely low latency.

Supported

Not currently supported

The system provides a fully documented open API for integration with consoles, controllers and automation systems.

Supported control protocols

Third-party consoles can control all parameters; control depth is not restricted.

Yes. The dMix 128 web interface allows multiple units to be displayed and controlled simultaneously from any browser.

The dMix 128 follows a matrix-core architecture with modular flexibility.

The open API and AES67 implementation allow dMix 128 to integrate into any mixed-manufacturer ecosystem.

These are the reset options:

The dMix 128 provides two hardware reset modes depending on how long the reset button is held while the device is powered on.

Reset mode 1 – Network reset (3 seconds)

With the unit powered on, press and hold the reset button for approximately 3 seconds.

Reset mode 2 – Factory reset (10 seconds)

Press and hold the reset button for approximately 10 seconds.
