thanks for the valuable info. However, I think I found out that the algorithm itself causes this low noise! Patch is #3910, I have examined it and I think that in this as well as in most patches that use feedback, there exists this noise. Other patches are very – very quiet upon loading.
I do however have a question about the optimal input level. Given the fact that the converters have a 26dBu headroom, Italo mentioned that 4 green LEDs are optimal, you say that the top green led needs to light from time to time, whereas the manual clearly mentions that the signal should be in the yellow area. I am a bit confused… so which is it?
Can you please explain what are the benefits from having a 26dBu headroom? Shouldn't the user be responsible for making sure that the signal never reaches 0dBu?
