Hiya all,
For my Senior Design project I am working on Active Sound
Attenuation. I am using a NeXT as my spectrum analyzer, which is
where my question lies. I would like to analyze the line out
of a sterio amplifier. What do I need to do to safely get that signal
into the mic input of the NeXT? I have tried two different methods.
One was running it straight in; all I got was static (well, actually
a hummmmm), I also tried a capacitor and resistor setup with the cap
on the NeXT side of the resistor. Does anyone have any suggestions? I
have no idea on what the rating of the mic in on the NeXT is, but the
line out on the sterio seems to be about 1.5V.
Any and all suggestion appreciated, Alex
