A unique feature of our SNES & Genesis YPbPr cables is that they are designed such that if you "split" the YPbPr input of a TV using Y-adapters, you can connect two HD Retrovision cables to the same port without degradation. This effectively acts like an auto-switching function. You cannot have both consoles powered on at the same time or you'll get garbage on the screen. Also, do not mix a mono audio device (e.g. Master System) and stereo audio device on the same split, otherwise you will get crosstalk on the stereo device. For caveats with PlayStation consoles, please see our PlayStation page.
IMPORTANT: This method only works properly with HD Retrovision SNES & Genesis YPbPr cables (including adapters) and not with other standard YPbPr devices. Also not supported is the HD Retrovision PS2/PS3 YPbPr cable.
