The Extron PowerCage FOX AEX 104 Four Port Fiber Optic Audio Extractor is a modular board designed for the Extron PowerCage^® 1600 enclosure that enables independent processing and routing of audio signals in a fiber optic AV system. Each port accepts signals from a FOX Series transmitter, extracts the two-channel audio signal to provide balanced or unbalanced analog stereo output, and re-transmits the original signal to a FOX Series receiver. Output reclocking on the buffered pass-through maintains signal integrity, transmitting the fiber optic signal at the original power level. Featuring high-speed, all digital signal transmission of pixel-perfect video, audio, and control, the PowerCage FOX AEX 104 is compatible with FOX Series HDMI, DVI Plus, DVI, VGA, VGA/YUV, and AV transmitters and receivers.
