This compact transmitter uses HDBaseT™ technology to extend your HDMI® signal up to 230 feet (70 meters) over a single CAT5e or CAT6 cable, to an HDBaseT display, projector or receiver (sold separately). The transmitter supports Ultra HD and Full HD video resolutions (4K and 1080p), with support for the accompanying digital 7.1 audio.Easy and discreet installation 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.Use your own HDBaseT display, projector or receiver The compact transmitter works seamlessly with other HDBaseT equipment, such as HDBaseT displays, projectors, and receivers. The simplicity and versatility of this compact transmitter make it the ideal solution for transmitting an HDBaseT signal to a boardroom or classroom projector, enabling presenters in your office to quickly connect their laptop computer and share presentations or data sheets.Seamless integration with your existing infrastructure This transmitter extends HDMI and 7.1 surround sound over a single cable, unlike some HDMI extenders that require two cables and only offer minimal audio support.
