Omnidirectional Microphone The 4006A is without any doubt the most popular mic in DPA's standard range and has rightly earned its status as a worldwide recording standard. This highly sought after omni has forged its enviable reputation over the past quarter of a century by repeatedly exhibiting its total transparency in any recording situation, and by picking up incredible detail and depth of sound. The definition of its high-frequency characteristics across a wide range of instruments is undeniably impressive for the vast majority of miking applications.
