The Audio-Technica BP350ST-UB is a compact stereo condenser microphone with independent cardioid (mid) and figure-of-eight (side) elements in an MS arrangement, built for broadcast, production and field recording. The AT8547 power module switches between wide or narrow left-right stereo and discrete mid-side output, and the capsule can be mounted in the supplied low-profile boundary housing or on the 5" gooseneck with universal clip-on mount for discreet stereo pickup at sports, press conferences, theatre and studio productions.
