This is my first post here but I wondered if anyone had thought of this. I bought a couple of these Tube mic pres the other day for the express intent to use the cavern'ess room, inside the chassis, to mount two 1108 vintage mic pres. When one opens this thing up one finds so much room you could almost mount a couple of V72's and get away with it. I plan to put separate IP & OP XLRs on the back of the chassis and also bridge the OPs to the line in of the actual Behringer line in as well but not sure how to do this yet. There might be a way to use the phantom and pad from the behringer but not sure so I will likely begin by building out my own. I think, considering the unit can be had for under $150, this makes an extremely cheap and nice frame considering considering mountings usually run over $600us. Still trying to gain access to a schematic if anyone can help. Your thoughts on this are welcomed.
