The NEC Conference MAX expansion unit is analog wired and has distributed echo cancellation which effectively eliminates echoing. The noise cancellation feature removes background noises from fans or HVAC systems. The NEC Conference Max also features a full-duplex sound enabling participants to speak and listen at the same time without cutting in and out. Automatic level controls keep participants' audio balanced and consistent. First-mic priority eliminates hollow "tunnel" sound by activating only the microphone closest to the person speaking. The 3 microphones provide 360 audio pickup.
