AHM-32 is an audio matrix processor for sound management and installation. It is designed for audio distribution, paging, conferencing and speaker processing in a multitude of environments including corporate, hospitality, education, event and multi-purpose venues, retail, theatres, cruise ships and sports venues.

The AHM-32 processor is complemented by an extended ecosystem of remote audio expanders, remote controllers, interfaces, apps and software.

A family of portable, rack-mountable or wallmount audio expanders is available with a choice of proprietary point-to-point Layer-2 or Dante transport protocols.

A range of IP remote controllers is available for volume control, music source selection, preset recall and more. AHM can also integrate with third party devices over GPIO, TCP/IP, or industry standard control systems. The Custom Control editor and app from Allen & Heath offer more control options and tailored user interfaces for multiple users and device types, with kiosk and BYOD capability.
