The Extron WPB 107B wallplate is specifically designed for a standard one gang-sized junction box. It features pass-through connection points for computer video and composite video, and active, buffered inputs for computer audio and stereo audio, providing an affordable integration solution for classrooms, conference rooms, and other facilities where convenient, wall-mounted AV connectivity is required. The WPB 107B accepts unbalanced line-level stereo audio input signals and outputs them as balanced or unbalanced audio. A power loop-through feature provides power to both buffers with one power supply. The WPB 107B wallplate is made of metal and is available in a white finish. A matching mud ring and an external universal energy efficient power supply, replacement part # 70-775-01, are included.

Surface mount and in-wall junction boxes are sold separately. Includes Isolation Bushings: One each in red, green, blue, black, white, and yellow.
