Next days, I’ll get my UR824 and it’ll be mounted in a rack. The plugs on the back will be connected to a patchbay which have TRS of course. Do I need XLR2TRS cables (which I have to buy) from the UR to the patchbay? Does the UR provide the phantom power to the XLR connector only or to the TRS connectors also? In this case, a TRS2TRS patch cable (I have enough of them) would do the job.
