Allen & Heath announced firmware V1.6 for its AHM series of audio matrix processors, adding advanced tools that expand scalability and integration for commercial and large-scale installations. The update introduces Unit Stacking, enhanced third-party control and monitoring, and new feedback suppression technology for select models.

“With AHM V1.6, we’re expanding the possibilities for both commercial integrators and system engineers,” said Samantha Potter, commercial audio manager at Allen & Heath. “It’s a release that puts the best of both worlds into a single platform, opening up new applications in hospitality, entertainment, houses of worship, education and more.”

The new Unit Stacking feature allows multiple AHM processors to be managed, monitored and controlled from a single project within System Manager. This capability lets users design and operate larger, more complex systems while maintaining the same workflow speed and simplicity used in smaller installations.

Firmware V1.6 also extends third-party control and monitoring support, enabling AHM processors to integrate more tightly with devices such as displays, video switchers, microphones and amplifiers. Integrators can now view device behavior directly from IP controllers, giving end-users improved visibility during operation.

A new Feedback Suppression function debuts in V1.6, available on AHM-32 and AHM-64 processors equipped with the AEC/Processing Expansion card. It provides real-time frequency management across up to eight zones, helping prevent unwanted feedback and ensuring stability in reverberant spaces.

Additional updates include new ganging options for levels, delays and dynamics, building on the EQ ganging introduced in version 1.5. Workflow improvements—such as socket labeling, processing block visibility, global mute and level controls, and playback looping—aim to streamline system configuration. The update also adds embedded recall support with Allen & Heath’s dLive and Avantis systems, VLAN compatibility for SLink and gigaACE connections, and numerous backend optimizations.

“We are continuing to develop AHM in direct response to the needs of our customers,” Potter said. “With V1.6 we’re proving that powerful, scalable systems don’t have to come at the expense of workflow speed or audio quality, ensuring integrators and system engineers can deliver outstanding results in any application.”

Firmware V1.6 is available now for download from the Allen & Heath website.
