Is there a reasonably simple way to disable the global phantom power from the mic pres on the 12-48?
I makes my Shure 545d mics hum and sound thin. They work perfectly (and sound great) on preamps that don’t have phantom, and generally I don’t need phantom power from my mic preamps or mixers, as I have separate phantom power units and power supplies for my condenser mics.
I don’t mind modifying each channel if that’s necessary. Or is there a global phantom power supply that I can disable?
