The MMIO DEMUX-HDSDI is a small, compact de-embedder which extracts or de-embeds 2 channels of balanced analog audio from a 3G/HD/SD-SDI signal. The audio outputs are balanced, line level and therefore suitable for all professional equipment. This compact box requires a 12V DC power from an optional AC to DC power supply or 12 V external source, such as a camera or battery. For user confidence and convenience there are two LEDs that indicate the status of source signal and power.
