The Shure SM7B is a legendary microphone beloved by podcasters, broadcasters, musicians, and audio professionals worldwide. Known for its exceptional sound quality and versatility, this dynamic microphone has one significant characteristic that challenges many audio setups: its incredibly low output level. This unique trait means that selecting the right preamp is crucial to unlocking the SM7B’s full potential.
