These are the ideal vocalist microphones. The grille design significantly reduces pop and sibilance, and the internal shock mounting reduces handling noise. The true cardioid KMS 140 and hypercardioid KMS 150 both have a roll-off switch to reduce proximity effect. With the attenuation switch activated, the maximum SPL is an impressive 148dB. The KMS series is ruggedly constructed to handle the rigor of stage performance. Tight polar control over the entire frequency range significantly reduces sensitivity to acoustic feedback.
