I bought this product to connect a new LCD TV to a PC to make it easier to use the PC for educational purposes. I wanted to be able to transmit both video and audio from the PC to the TV since the PC is in one corner of the classroom and the TV is in the other. This device is powered by the PC and as I understand it takes signals from the PC and amplifies them enough to allow long term operation with two devices, most likely your PC's monitor/speakers and something else. The name of this product in Revain is a bit confusing as it mentions RCA but actually uses small 3.5mm headphone jacks that support PC. I used a 10ft Cables To Go M/M with 3.5mm audio jack (43096) to get from the PC to the splitter and then a similar 50ft cable (43100) to connect to connect to the TV. These cables save you the hassle of using two separate cables - one for the monitor and one for the audio. (I had one last complication, which was that the TV needed a couple of RCA inputs for audio, so I needed an RCA adapter for a 3.5mm stereo mini phone.) This splitter extension is really well done , very compact and strong. I wired everything up using an existing cable from a PC monitor/speakers to connect as a second output. The result is really great. The picture and sound quality of the TV is excellent. Now the instructor can sit at a desk and project webcasts, show CD videos, demonstrate website usage, or project presentations on a large TV 25 feet away.
