Hey,
I'm working on designing a 5-input > 1 output stereo audio mixer. How would I prevent the an input signal from backfeeding into other input lines? A diode will not work in this case, as the signal is < .7v.. my only idea is to make an amplifier for each input so that each signal is > .7v, but there's gotta be a better way! The output will feed into an external amp so this seems horribly inefficient. Ideas?
