The KSM8 is a first-of-its-kind dual diaphragm dynamic handheld vocal mic. There’s a mouthful for ya. What does it mean? The soundbite version is that the second diaphragm works to control both the proximity effect common on directional microphones and to increase the rejection of more distant sound sources. The whole idea is a dynamic mic that doesn’t pick up much of anything in terms of off-axis sound and that is tonally consistent regardless of if the singer is an inch away from the grille or three inches away.
