My primary mic that I play through my SJ 410 is a Shure white label controlled reluctance (CR) cartridge installed in an ElectroVoice 605 shell. Mic #2 is a Shure black label controlled reluctance (CR) cartridge installed in an ElectroVoice 605 shell. I plug into input main 1, and bridge channels (main 2 to bright 1). Andy Vincent
