How do you insert 2 GAP-73 pres to master buss?

Yeah, 2 GAP73 pres as a sort of an summing stage/warmer in the master buss? I have ADA8000, it has XLR outs but I guess I have to use the TRS-inputs when going back to ADA8000? So, how...?

I would imagine you would need XLR to TRS adaptors or cables. Then, couldn't you just put ReaInsert on the master bus routed to the converter outputs and back into the inputs.

Just did it with ReaInsert, XLR outs from ADAT -> TRS input on GAPs, then XLR outs from GAPS and TRS input to ADAT. GODDAMN sounds good and warm!!!

Great idea, I'll try this now, gap pre-73's sound killer at any price.
