@mbrancalion IMHO, You should adjust the threshold to your bass rather than copying @bass40hz It's okay to copy the other settings.
Before posting the original post, i tried literally EVERYTHING. Also using very small turns, in every knob, one at a time.
Trust me, i know what compressor are, and i know how to search and tweak sounds.
In my opinion, this was the final test. If anyone, builder included, is able to point me to other observation or tests, i'll be ready to listen. Otherwise i'm really done (like someone was insinuating).
I beg the builder to INCLUDE in his website the specs he sent me by email (he reported my emails, so i'll do the same):
"The DE-CL uses full-wave peak detection in it's threshold circuits. The threshold detector circuits are designed to be flat-full-band for frequencies above 80Hz and to be approximately +3dBu more sensitive at 40Hz and +6dBu more sensitive at 30Hz. You could use an EQ at the input of the DE-CL with a gentle roll-off on the frequencies below 80Hz and another EQ after the DE-CL to bring those frequencies back up to normal. This may help with issues that you are having.
Another thing to note is that the COMP and LIMIT LED's are only indicators for threshold + attack. There is a brief period of release cycle compression after the LED's just extinguish. This thresh+attack indicator made it easier for me to find my settings when playing live."
If i had read online something similar before, i'd never payed $$ to a builder/seller, that now seems happy whatever my position is.
Once again: i'm disappointed. In all these years i always saw a more serious behaviour in standing behind their products, by US sellers.
So, i hope this thread and eventually the specs reported clearly in the FEA's website will be useful to someone else in the future. It's a shame to see so many selling ads of the DE-CL ......
