Splitting one signal into two
It worked! I am using this cable to send the single stereo signal from my computer audio board to my stereo amplifier and also to the compressor to amplifier. I needed to run my Netflix movies through the compressor to get the annoying wide dynamic range under control. But I also want a straight line to my amp without going through the compressor to avoid the extra cable routing and bypass of the compressor so I can have a pure line to the amp. This cable split it up and gives good signal levels straight to my amp and also through the compressor to the amp. It worked! I did not need a switch box, keeping this simple and cheap.
