Allen & Heath M-AHM-32-AX AHM-32 Echo Cancel Module 12ch AEC FIR Filters

Allen & Heath M-AHM-32-AX is an Acoustic Echo Cancellation (AEC) module for the AHM-32 matrix processor, providing 12 channels of advanced echo suppression for teleconferencing and videoconferencing environments. It uses 150ms FIR adaptive filtering, far-end automatic gain control (AGC), non-linear processing (NLP), and background noise reduction. Each AEC processor is inserted into the far-end and near-end signal paths, with optional reinforcement output for local voice amplification. The module installs internally and operates independently of the I/O port, allowing simultaneous use with Dante or other expansion cards.
