Im having problems with my FOH sound, im using a Orange Terror Bass Head, SP410 cabs. Phantom Power in on the desk, and you can't just set it to certain channels. So the problem is when i go through the DI on the head im being told to turn down on stage (and theres nothing on the fader for the bass on the desk) and if i turn down i cant hear myself... is this because phantom power is on. If i use my seperat DI it runs of phantom power but im still having the same problem. I could mic up but im not really a fan of it, but if i need to mic it, where would be the best place to place the mic on the SP410 cabs?
