Only now there's another problem, lower set, -30db is lit even without signal applies, checked with scope and there is 1.2v dc bias so no wonder they are lit. Placed capacitor, dc is gone, but now it behaves even more strangely: at first, leds light like they should, but when second set starts to light, lower ones start to fade?
so, instant-mode works, but when i put peak-circuit, no matter before or after amplification, things go sour, only first few leds light. I don't have virtual ground anywhere
and both amplification and peak-detection is built in same lm358
what is strange also, when i switch that 330k to 330r, it works better in peak-mode, more leds are lit?
