I'm confused.
I've always assumed that phantom power feeds to mixer mic pres need to be isolated from each other, i.e., each strip has its own dedicated 48VDC supply. However, my Soundcraft 6000 desk PSU has just one global feed that supplies all 24 channels. How do they keep them isolated from one other??
