Hey Carol, I've got an old stereo component by AudioControl with a real time spectrum analyzer and pink noise generator but I'm not one of those boys that makes a whole lot o' noise when he plays. Can this still work to my advantage? I hooked it between my Phase Linear 400 and my Samson mixer and it picks up the signal and allows me to play with it n the EQ the pink noise input is separate and has a mic jack input next to it. I'm not sure what two lines to connect to it, the ones from my mixer I'm guessing. Is that correct? I got it a garge sale and it came with no instructions. Does the pink noise get pumped to the mic as the noise is fed via the speakers? Then the analyzer detects the proper balance or do I set the balance near flat or as it sounds good to me???
