I think I've decided not to make the DI impedance switchable on the front panel on the ML12 build. The DI boards right now have a jumper where you can set it to 1 meg or 10 meg. I was going to put a connector there where the jumper block normally would have been, and run leads to switches on the front panel. This also would have meant relocating parts to the underside of the PCB to make room for the connector. Not worth it for the once every 2 years I will need a 10 meg DI.
