line level sensor input auto power switch (audio)
hi all. I'm thinking about trying to make a circuit that would automatically switch on my subwoofer when a signal is detected on the line input.
I think line level is around 2v but im not sure on that? Also how would you suggest to avoid it turning off on areas of audio with little or no signals coming into the sub?
thanks
