So I've been away for a while but I wanted to share one of my recent projects.
I've been itching to get rid of the stock summing amps in my console and today while the crew was finishing work on a new isolation booth in the studio I thought I would take the time to work some FETblokes into the summing network.
I figured out the buss impedence and then went from there. I removed all the parts related to the summing amp including the BJT frontend, the opamps and resistors and replaced them with a FETbloke and it's feedback network and some pots for trimming the gain.
Needless to say it works great.
In fact it works so great that my noise floor dropped 15db.
15db!
even with the faders fully up and inputs idle, my noise floor is now below 70 when it was previously at -40 with the faders up.
I'm pretty sure I hear a small difference in the sound but not much.
I mentioned removing this section before but many told me that it was fine. I suggest that anyone thinking about this give it a try after they do their math and see if it works for them.
