Matrix processing for installed audio sits here, in the shape of Allen & Heath’s AHM family: the AHM-16, AHM-32 and AHM-64 digital matrix processors, plus their echo-cancelling expansion modules and mounting hardware in the sub-categories. These are the boxes behind multi-room venues, conference facilities, hospitality sites and houses of worship, routing any input to any zone with per-zone processing, loudspeaker EQ and priority ducking for paging.

The three sizes map to matrix count, 16×16, 32×32 or 64×64, and the right unit is set by how many sources and zones the site needs now plus sensible headroom for phase two. AEC modules matter for conferencing spaces where microphones and loudspeakers share a room, so add them wherever far-end callers are part of the picture. Control is the other half of the design: AHM pairs with the IP series wall controllers and CC-10 touch controller from the Personal Mixers and IP Controllers category, and takes the same option card ecosystem as the SQ console range for audio networking.

Speccing a zone system usually raises more questions about control philosophy than DSP, and it is worth mapping who adjusts what in each room before choosing hardware.
