Allen & Heath AHM AEC/FBS Processing Expansion Card

The AHM AEC/FBS Processing Expansion Card adds acoustic echo cancellation and feedback suppression directly into an AHM-32 or AHM-64 matrix processor, built for videoconferencing rooms and any install space where open mics and loudspeakers share a room.

A single card carries up to 12 channels of AEC and up to 8 instances of FBS, so a conferencing system gets clean, echo-free pickup and a fixed installation keeps feedback under control without outboard hardware. The card is model-specific: order the AHM-32 or AHM-64 version to match the processor already in the rack.
