The compact transmitter uses HDBaseT™ technology to extend your HDMI® signal up to 230ft (70mtrs) over a single CAT5e or CAT6 cable, to an HDBaseT display, projector or receiver. The transmitter supports Ultra HD and Full HD video resolutions (4K and 1080p), with support for the accompanying digital 7.1 audio. For a simple and tidy installation, the HDBaseT transmitter features a small footprint and a built-in HDMI cable that connects directly to your video source, reducing clutter by eliminating the need for an HDMI cable at your local source. The transmitter is powered using USB, which means you can use a USB port on your source device to power the transmitter, which is perfect for extending from areas where power outlets may be limited.
