Clear, natural and accurate - for PA systems and venues of all sizes. Audix's OM3 is used for a variety of live, studio and broadcast applications. This mic provides accurate sound reproduction, resistance to feedback and ability to handle very high SPLs without distortion.The OM3 is made with a tight and uniformly controlled hypercardioid polar pattern that isolates the vocals from the rest of the instruments on stage.A slight natural roll-off in the lower mid-bass frequencies allows the OM3 to reduce boominess and handling noise. This, in conjunction with an extremely articulate mid-range, makes this mic an excellent choice for PA systems of all sizes.
