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.\u003c\/p\u003e\u003cp\u003eAs 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.\u003c\/p\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eProcessing expansion module for the AHM-64 matrix processor\u003c\/li\u003e\n\u003cli\u003eUp to 12 channels of acoustic echo cancellation (AEC)\u003c\/li\u003e\n\u003cli\u003eUp to 8 instances of feedback suppression (FBS) with 25 live or fixed bands each\u003c\/li\u003e\n\u003cli\u003e150ms FIR adaptive filter\u003c\/li\u003e\n\u003cli\u003eFar-end AGC (Automatic Gain Control) and near-end gating\u003c\/li\u003e\n\u003cli\u003eResidual echo non-linear processing and background noise reduction\u003c\/li\u003e\n\u003cli\u003eSpeech-shaped comfort noise\u003c\/li\u003e\n\u003cli\u003eConfigured from AHM System Manager software\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatibility: Allen \u0026amp; Heath AHM-64 only\u003c\/li\u003e\n\u003cli\u003eAEC Channels: up to 12 (one AEC reference per setup)\u003c\/li\u003e\n\u003cli\u003eFBS Instances: up to 8, 25 bands each, mono or stereo zones\u003c\/li\u003e\n\u003cli\u003eAdaptive Filter: 150ms FIR\u003c\/li\u003e\n\u003cli\u003eInstallation: slides into the AHM-64 processing expansion slot, Torx T8 screwdriver\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: AH-M-AHM-64-AEC-A\u003c\/li\u003e\n\u003cli\u003eUPC: 6938122250949\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\u003c\/ul\u003e","brand":"Allen \u0026 Heath","offers":[{"title":"Default Title","offer_id":50957072269509,"sku":"ALHT-AHMAHM64AECA","price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/1-allen-heath-ah-m-ahm-64-aec-a_05a0287f-3237-4248-a8d9-8d66ae85cf3d.jpg?v=1794513865","url":"https:\/\/avlgear.com\/products\/allen-and-heath-m-ahm-64-aec-a-echo-cancellation-module-for-ahm-64","provider":"AVLGEAR","version":"1.0","type":"link"}
