Allen & Heath expands third-party control options for AHM matrix processors

Background and context

Allen & Heath is extending the role of its AHM audio matrix processor range in installed AV environments by focusing on easier integration with third-party devices. The UK-based manufacturer is targeting system integrators and engineers who need centralized control across mixed-brand setups in meeting rooms, conferencing spaces, and multi-purpose venues.

The AHM series has been positioned as a flexible platform for commercial audio installations, with an emphasis on scalable processing and customizable user interfaces. The latest developments centre on making it simpler to connect and manage other manufacturers’ products directly from within an AHM-based system.

Key announcement

The core of the update is an expanded library of Device Control Files (DCFs) that allow AHM processors to communicate with external hardware and software. These files define how the AHM system interacts with third-party equipment, exposing key parameters and functions for day-to-day operation.

Integrators can either create their own DCFs or use pre-built drivers supplied by Allen & Heath. The company says these ready-made files are designed to cover the most commonly used controls, reducing setup time on projects where standard functions are sufficient.

The AHM platform is tightly integrated with Allen & Heath’s Custom Control application, IP controllers and CC touch panels. This means once a DCF is loaded, integrators can surface third-party controls on tailored user interfaces for end users, such as wall panels or tablet-based control screens.

According to Allen & Heath, current collaborations include support for Audio-Technica ES Wireless, ATND and System 20 PRO products, Sennheiser TeamConnect ceiling solutions, and a range of devices from Visionary Solutions. There is also support for general PTZ camera control and projector control, aimed at typical conferencing and presentation environments.

These files can be used as delivered or further customized based on the third-party product’s API, giving more advanced users scope to extend or refine control options.

Industry impact

For AV and event technology professionals, cross-brand interoperability remains a major consideration when designing systems for corporate, education, hospitality and live event spaces. Processing platforms that can act as control hubs for multiple device types can help reduce the need for separate controllers or bespoke programming.

By leaning into DCFs and pre-built integrations, Allen & Heath is positioning AHM as a central element in mixed ecosystems where microphones, DSP, cameras, video-over-IP devices and projection systems may all come from different vendors.

The company is also supporting this strategy with training resources. It offers a free on-demand course covering AHM as well as live online certification focusing on AHM deployment. In addition, regular online Control Network Certification classes address DCF creation, third-party control workflows and graphical interface design. Details of these resources are available via the Allen & Heath website at allen-heath.com.

Why this matters

For system integrators, the ability to deploy pre-configured control files can shorten commissioning times and lower programming overheads, especially on repeatable room types or multi-site projects. Having common functions already mapped also reduces the risk of errors when integrating equipment from several brands.

For venue operators and technical teams, tighter integration can translate into simpler user interfaces, with audio, camera and projection controls accessible from a single touch panel or app rather than multiple remote controls or software tools.

As AV installations increasingly combine audio processing, networked microphones, software-based conferencing and IP-based video distribution, the demand for open control frameworks is likely to grow. Allen & Heath’s focus on expanding AHM’s third-party control capabilities reflects this shift and adds another option for those looking to standardize on a central processing and control platform in modern event and install environments.
