The Shure SM7dB is the SM7B with a Shure-designed active preamp built in: switch in +18dB or +28dB of clean gain, powered by ordinary 48V phantom, and the classic broadcast dynamic drives any budget interface without an external booster. A bypass switch reverts to the identical passive SM7B signal path.
