I have a simple solution sought to connect an RCA and a YUV cable through a distributor with two RCA inputs and two input sources, in which case once my TV and even a Dazzle, a recording device to record videos of my SNES to other consoles and on PC / laptop to record.
This RCA adapter I've found a highly affordable and satisfactory solution, RCA cable my console using 3 of these RCA adapter and an additional YUV cable to my TV and the Dazzle connected, the signal transmission works smoothly and the shooting stands now no more obstacles.
The plug connections are tight and do not wobble, neither in connection with the Dazzle, the RCA cable from the SNES still the YUV cable. The processing is therefore as the signal transmission properly!
From my very clear "thumbs up" for this RCA distributor, my expectations have been met to my complete satisfaction!
