Used to extract the audio from any HDMI video signal for connection to audio equipment The Hall Research EMX-HD-AUD HDMI Audio Extractor with EDID Management is used to extract the audio from any HDMI video signal for connection to audio equipment. The HDMI signal is reconditioned and boosted as it passes through the device, so it can also serve as an extender. The EMX-HD-AUD also provides useful diagnostic information that can help is resolving compatibility of components in the video signal chain. It can be powered from the HDMI source connected to its input and no additional power supply connection is needed for most applications. The audio extractor also features EDID management (pass-thru or emulate), So it can emulate any HDMI display and is capable of extracting the audio even if no actual display is connected to the output. Both Toslink (digital) and two channel stereo analog outputs are available on the device. The EMX-HD-AUD is an HDMI transceiver, so it not only re-clocks the video data, it also separates and buffers the DDC channel on which EDID and HDCP are communicated. This can often resolve system-level HDMI signal-chain issues since the EMX-HD-AUD acts as an intelligent intermediary. The package includes a universal power supply in case the power from the HDMI input source is insufficient. The power supply is plugged in at the USB connector. When the USB port is connected to a PC (cable supplied), the unit is powered by the PC through the USB connection. Providing real-time status on the HDMI video and audio signals Multi-color LEDs on the unit indicate the mode of operation with regards to EDID routing, and also provide real-time status on the HDMI video and audio signals. For example the LEDs can identify presence of audio and whether it is 2-channel or multi-channel. Similarly the detection of video from source is indicated and it identifies whether there is HDCP on the video or not
