VDM-1x HDMI Downscaler with Downmixer

The VDM-1x video scaler and digital audio converter (DAC) is the ideal solution to accommodate HD (1080p) and 4K sources and displays within a multi-zone residential or commercial installation. The unit is designed to be placed between a display and a source device and it adjusts video resolution (upscale or downscale) and audio (downmix or bypass) from an incoming HDMI source and scales the output to a level compatible with the display capabilities.

Included in the box:
VDM-1x, Power Supply 5VDC/2A
