Audio Network In-wall Interface Control Panel

MediaMatrix nWall is a surface mount CobraNet interface panel with two analog microphone/line level input channels. The device converts audio from the input channels to a CobraNet audio stream. It can then be routed via CobraNet bundle transmitters over a local area switched network using CAT5e UTP cable. nWall eliminates the need for long runs of analog microphone cables terminated in racks of patch bays as typically seen in ballrooms and convention centers. As the connection to the nWall uses CAT5e UTP cable with network standard RJ45 crimp connectors, the installation time, number of terminations required and associated cost are all minimized. A MediaMatrix nWall CobraNet interface panel fits within a standard 2 gang NEMA back box and is powered over the attached network cable from a network PoE capable switch that conforms to IEEE 802.3af. The XLR connectors can be configured for multiple audio input sensitivities (-56, -26 and +4dBu) using a rotary switch on the front panel. Electret condenser and dynamic microphones are supported, plus line level audio with 15V DC phantom power assigned to the XLR inputs. The 1/8-inch (3.5mm) TRS mini jacks accept a nominal -8dBu signal that is summed to mono and mixed with the XLR inputs.
