Engineered for professional broadcast, production and field recording applications, the BP350ST-UB features independent cardioid and figure of eight elements configured in an MS (midside) arrangement with switch selectable internal matrixing. The mic element can be mounted using either of the two included mounting solutions – a low profile boundary housing and a 5" gooseneck with clipon mount – to enable inconspicuous capture of true stereo sound
The BP350ST-UB midside capsule arrangement provides crisp, clear, well balanced stereo response, even at high SPLs. A switch on the included AT8547 power module allows users to choose between left right stereo output (wide or narrow) and discrete midside signals for later manipulation. Midside operation offers many advantages for postproduction editing, making it easier to place voices naturally in a mix, for example, and providing audio that won’t lose its depth when stereo channels are combined into a mono track. The two mics in one configuration also helps reduce common problems with stereo miking, such as time alignment and comb filtering
The BP350ST-UB’s element is enclosed within the same compact body as our popular ATM350a instrument mic, allowing it to be used not only with the included boundary housing, gooseneck, and clipon mount, but with any of our ATM350a mounts and mounting systems. The snapon grille of the included boundary housing provides easy access to the mic, which locks securely into the boundary’s base plate. The back of the plate is magnetized for easy mounting on metal surfaces and also includes four holes for screw mounting. With the gooseneck and clipon mount, the mic can quickly be positioned in any number of locations for ideal, close to the action sound pickup. The AT8491UC clipon mount includes a ¼" camera thread for use with a tripod or other device
The mic’s permanently attached 7.6 m (25') cable is terminated with a TA5F connector that plugs into the power module. A switch on the power module allows users to select an 80 Hz high-pass filter to suppress unwanted ambient noise. The power module comes with a 36 cm (14.2") TA5F to dual XLR3-M stereo cable that’s suitable for connecting to any traditional mic preamplifier with phantom power
