Description
The 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 and Heath offer more control options and tailored user interfaces for multiple users and device types, with kiosk and BYOD capability.
