yes, I tried ALL EQ Compressor presets, also tried to move all single knobs. ALways same results. NO signal through. Only some low noise. Also tried to up the signal of my mic after preamp. The signal was totally distorted because it was too high BUT still no signal goin through.
It's nightime here in Italy right now BUT tomorrow I'm gonna try your last suggestion to do a complete system restore and let you know here the result.
finger crossed! 🙂
