These AEC Input Cards enable Soundweb London devices to cancel acoustic echo arising when sound from a loudspeaker enters a microphone in the same room in a conference application.\u003c\/p\u003e\n\u003cp\u003eLike the Soundweb London Analog Input Cards, the Soundweb London AEC Input Cards offer Phantom Power, configurable per channel and software controlled analog gain in 6dB steps from 0dB to 48dB.\u003c\/p\u003e\n\u003cp\u003eThey offer four independent channels of AEC which can be freely configured in software and individual AEC references allowing users to provide a solution for multiple spaces using a single device.\u003c\/p\u003e\n\u003cp\u003eAutomatic Gain Control (AGC) ensures that the inputs of the microphones are set at the optimum level. Noise Cancellation (NC) removes steady state noise (such as from a projector fan or air conditioning device) from the signal path. This stops the noise from being amplified.\u003c\/p\u003e\n\u003cp\u003eNon-Linear Processing (NLP) dynamically adjusts to minimize echo caused by under or over-cancellation.\u003c\/p\u003e\n\u003cp\u003eThe Soundweb London AEC Input Cards also offer a direct microphone feed for local sound reinforcement. This allows full-bandwidth, low latency, direct microphone signals to be mixed and processed for local sound reinforcement purposes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with BLU-800, BLU-320, BLU-160 and BLU-120 Devices\u003c\/li\u003e\n\u003cli\u003ePhantom Power (Configurable per Channel)\u003c\/li\u003e\n\u003cli\u003eSoftware Controlled Analog Gain (0dB to 48dB, 6dB steps)\u003c\/li\u003e\n\u003cli\u003eFour Independent Channels of AEC\u003c\/li\u003e\n\u003cli\u003eIndividual Reference per Channel\u003c\/li\u003e\n\u003cli\u003eAutomatic Gain Control (AGC)\u003c\/li\u003e\n\u003cli\u003eNoise Cancellation (NC)\u003c\/li\u003e\n\u003cli\u003eNon-Linear Processing (NLP)\u003c\/li\u003e\n\u003cli\u003eDirect Microphone Feed for Local Sound Reinforcement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAEC Input Card\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConnector 1\n\u003cul\u003e\n\u003cli\u003eBalanced \/ Unbalanced Audio, Channel 1 - Mic\/Line\u003c\/li\u003e\n\u003cli\u003eBalanced \/ Unbalanced Audio, Channel 2 - Mic\/Line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eConnector 2\n\u003cul\u003e\n\u003cli\u003eBalanced \/ Unbalanced Audio, Channel 3 - Mic\/Line\u003c\/li\u003e\n\u003cli\u003eBalanced \/ Unbalanced Audio, Channel 4 - Mic\/Line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog Inputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 16 electronically balanced on Phoenix\/Combicon removable screw connectors\u003c\/li\u003e\n\u003cli\u003eMic\/Line Inputs: Nominal gain 0dB, electronically switchable up to +48dB, in +6dB steps\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 3.5kΩ\u003c\/li\u003e\n\u003cli\u003eMaximum Input Level: +20dBu with 0dB input gain, +8dBu with 12dB gain\u003c\/li\u003e\n\u003cli\u003eCMRR: \u0026amp;gt;75dB at 1kHz\u003c\/li\u003e\n\u003cli\u003eInput Noise (E.I.N.): \u0026amp;lt;-128dBu typical with 150Ω source\u003c\/li\u003e\n\u003cli\u003ePhantom Power: 48V nominal, selectable per input\u003c\/li\u003e\n\u003cli\u003ePre-AEC Input Latency: 38\/Fs [0.79ms@48k]\u003c\/li\u003e\n\u003cli\u003ePost-AEC Input Latency (Original 8k Algorithm): 2385\/Fs [49.68ms@48k]\u003c\/li\u003e\n\u003cli\u003ePost-AEC Input Latency (Full Bandwidth Algorithm): 1609\/Fs [33.52ms@48k]\u003c\/li\u003e\n\u003cli\u003eTail Length: 200 ms\u003c\/li\u003e\n\u003cli\u003eAverage Convergence Rate: 49dB\/s (Net convergence over multiple FFT bands)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BSS","offers":[{"title":"Default Title","offer_id":42421868331087,"sku":"BLUAECIN","price":2159.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/9466\/9382\/files\/BSS-BLUAEC-IN.jpg?v=1737564647","url":"https:\/\/shop.musicredone.com\/products\/bss-bluaecin-4-analog-input-mic-line-card-for-soundweb-london-chassis","provider":"RedOne Music Canada","version":"1.0","type":"link"}
