Hello, live engineer currently having a discussion where a colleague isn’t quite grasping the variables of running DI well. I feel like I understand it in a practical sense and how to and how not to do it but I’m having trouble articulating why, so can someone offer an explanation where I’m swaying and calling the client an idiot? Scenario; want to run a DI line as a backup to amp dying However the player refuses to use anything “common” for their high gain playing, aka they won’t plug into any XLR equipped direct gear in the realm of samsamp/ darkglass/mxr m80 etc. for what reason I don’t know, especially when playing low end metal. They expect to use (example) bass> pro co Rat> any DI box without any kind of cam sim/emulation which is obvious going to be an impedance mismatch and disgustingly fizzy. Now I know this is a terrible idea, and to bend to them slightly I’ve offered the orange Bax preamp with a Cab sim out as a halfway solution for a decent direct line (but they still won’t even use that out, and now for a frustrating reason want to use the usual out designed to hit the amp and go straight to PA..!!) Can someone please give a home-run answer as to why, despite there being a signal, this is a bad idea and why it’s impractical, and the simplest explanation to the difference of a general DI signal opposed to how the signal sends from a darkglass/sans/Kemper etc? Thanks!
