Allen & Heath M-AHM-64-AEC-A Echo Cancellation Module for AHM-64

Clear speech in both directions is what makes a hybrid meeting work. Fitted to the processing expansion slot of an AHM-64 matrix processor, this module adds dedicated hardware for acoustic echo cancellation, removing the echo that far-end callers would otherwise hear when their voice is reproduced in the room and picked up again by the microphones.

As many as 12 AEC channels are available, assigned via the inserts on input channels with one AEC reference per setup, so multi-mic boardrooms and lecture spaces are covered. Where feedback is the bigger problem, the module can run up to 8 instances of feedback suppression on mono or stereo zones, each with up to 25 live or fixed bands.

Installation takes minutes: remove the four screws on the AHM-64 expansion slot cover, slide the module into the guides and mating connector, and refit the cover. Setup and operation are handled in AHM System Manager.
