It includes a transmitter and a receiver, which together can transfer a 4K/30Hz video signal up to 40 meters (about 131 feet) away over a single CAT-6 Ethernet cable. For 1080p signals, the range extends to 230 feet. These units are ideal for connecting an A/V receiver to an overhead projector or wall-mounted TV, without the need for an expensive, ultra-long HDMI cable. How the system works The transmitter balun connects to your home theater receiver, Blu-ray player, or other video source via a short HDMI cable. It then sends the incoming signal through a CAT-6 cable to the receiver balun, which is located near your TV or projector. A short HDMI cable is used to connect the receiver balun to your display. What is a balun? A balun gets its name by converting signals between balanced and unbalanced lines. Balanced cables carry signals over much longer distances than unbalanced lines, and also provide superior noise rejection. These baluns convert HDMI to balanced CAT-6 connections. The result is clear, crisp signal transmission that offers flexible placement options for your equipment.
