The Audio2000'S® ACM190 The Audio2000'S® ACM191 shotgun microphone is a premium quality supercardioid condenser microphone. The ACM191 retains a true supercardioid pickup pattern throughout its frequency range. This uniform supercardioid pattern greatly reduces off-axis coloration, increases separation between adjacent sources, and reduces feedback.

The ACM191 also features an open-cage design for minimizing any disturbance to the smooth polar pattern. Moreover, a newly designed internal shockmount effectively minimizes mechanically transmitted stand and handling noise.

The microphone's uniquely handsome and rugged mesh grille is precisely machined for extended life and durability.


  • The standard ACM191 package includes an ACM191 condenser microphone, a microphone holder, a shotgun microphone windscreen, and a 20' low-impedance microphone cable in a deluxe PVC box with a cardboard cover.
