Personally, I have a 5.1 Headphone with control box (on the table in front of me), and it looped through the stereo output to the console, because the amplifier.
Noise occurred to me until now not yet.
Additional 1:
Now I take me the time to add the assessment that the two RCA cords are occupied in my case with the wrong colors, you mean, red is white and white is red.
This may be an exception, but is annoying (been).
Addition 2:
Apart from the workmanship, I have called in extra 1, has emerged after a long operating time that this cable is only suitable if you would once pocketed and then never touches to end of life again.
The connectors are extremely strong, which in itself is not bad, but:
1. Plug the sheath is very short and the surface is very smooth.
So without further ado you do not get the plug back out of the socket as the plug is not handy.
2. I have the envelope of an RCA jack with torn in my amplifier, they sat on the plug.
I have now had enough of it - into the dustbin.
