Eight independent channels of Extron AEC sit ahead of the matrix, with a tail length beyond 200 milliseconds and convergence up to 60 dB per second, which is what keeps a far-end participant from hearing their own voice come back at them. Selectable noise cancellation of up to 20 dB works alongside it. Extron's algorithms are tuned for the hard cases: double-talk, where both ends speak at once, and near-end wireless microphones that move around the room. DSP Configurator meters ERL, ERLE and total echo reduction in real time and flags when echo return loss falls outside the useful range. Everything else is standard DMP 128: twelve mic\/line inputs, eight outputs, automixing and an expansion port.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEight independent channels of Extron acoustic echo cancellation.\u003c\/li\u003e\n\u003cli\u003eAEC tail length over 200 msec with convergence up to 60 dB per second.\u003c\/li\u003e\n\u003cli\u003eSelectable noise cancellation of up to 20 dB.\u003c\/li\u003e\n\u003cli\u003eTwelve mono mic\/line inputs, eight with switchable +48 VDC phantom power.\u003c\/li\u003e\n\u003cli\u003eEight mono outputs, or four stereo, with automixing across up to eight mic groups.\u003c\/li\u003e\n\u003cli\u003eExpansion port carries 16 channels each way to a second unit or a DTP CrossPoint.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eConference rooms and boardrooms running audio or video calls, courtrooms with remote testimony, training and telemedicine spaces, and any room where local reinforcement and a far-end connection share the same microphones.
