So, I had a look at the schematic. The adapter is supposed to be running XLR pin 2 as RCA left and right hot, and XLR pin 1 and 3 as RCA left and right sleeves. If you lift the ground, you arw still getting pin 3 signal, but no ground loop? Strange
EDIT: You beat me to it
Great thread! I just learned a lot.
See again, I am pretty sure my BDI-21โs ground lift switch was wired backwards
Update:
I figured out how to properly use my DAI as a PC output and a bass input.
It isnโt the solution to my posted problem, but itโs clean in both directions and a success
Also, I like the BDI21 for tone out of the amp!
