audio technica / BP350ST-UB

BP350ST-UB compact MS stereo microphone combines separate cardioid and figure-8 capsules for broadcast, production and field recording. The AT8547 module selects raw MS, wide stereo or narrow stereo output.

The capsule supports low-profile boundary housing or 5-inch gooseneck with clip mount, preserving sightlines for fixed indoor/outdoor stereo capture. MS capsules handle high SPL and allow easy stereo-width adjustment and mono conversion; co-located capsules minimize time-alignment differences.

The capsule uses the same compact form as ATM350a instrument microphones and accepts compatible optional mounts. A snap-on boundary grille provides easy access; rear magnets and four screw positions allow secure attachment.
Gooseneck and AT8491UC clip allow quick, precise placement, including a 1/4-inch camera thread for tripods. Integral 7.6 m cable connects by TA5F to AT8547, with switchable 80 Hz HPF. Includes a TA5F Mini XLR5-to-XLR3 cable for phantom-powered preamps.

Suitable for sports broadcasting, press conferences, theater and studio recording
