This processing expansion module gives the AHM-32 matrix processor dedicated hardware for acoustic echo cancellation, detecting the echo in the far-end feed along with residual room effects and minimising it.\u003c\/p\u003e\u003cp\u003eUp to 12 channels of AEC can be assigned through the inserts on input channels, supporting multi-microphone conference setups with a single AEC reference. The same module can instead provide up to 8 instances of feedback suppression on zone channels, each with up to 25 live or fixed bands, to tame troublesome voice-lift and sound reinforcement systems.\u003c\/p\u003e\u003cp\u003eThe module fits inside the AHM-32 chassis, plugging into the mating connector on the main board and fixing through its four pillars. All AEC and FBS parameters are then available in AHM System Manager.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eProcessing expansion module for the AHM-32 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-32 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: internal; top panel removed, Torx T8 screwdriver\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: AH-M-AHM-32-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":50957072236741,"sku":"ALHT-AHMAHM32AECA","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-32-aec-a_9708cca7-8e8e-4798-a4a0-0857bbe6258f.jpg?v=1794513860","url":"https:\/\/avlgear.com\/products\/allen-and-heath-m-ahm-32-aec-a-echo-cancellation-module-for-ahm-32","provider":"AVLGEAR","version":"1.0","type":"link"}
