Glad you’re sorted and happy with the amp so far.
I find when you do use the compressor it’s best around 9 to 10 o’clock
Drive only on a small amount when required, I think mine is only just on when engaged. SUB use sparingly as a little goes a long way on the low notes
mostly I leave drive and sub off though
I also run my input control at about 12 o clock which according to the needle very low to mid input. With such a lot of output power you have plenty of volume trust me
Mine is with a passive bass
