Built for creators and audio professionals who need focused stereo sound in fast-moving environments, this compact microphone features a 6.3\" interference tube that helps reject off-axis noise while focusing on distant sound sources. Its lightweight camera-mount design makes it a strong choice for run-and-gun filmmaking, live event coverage, interviews, documentary work, and location recording where mobility and accurate stereo imaging matter.\u003c\/p\u003e\n\n\u003cp\u003eUsing a mid-side stereo capsule configuration, the BP350ST-UL combines independent line-cardioid and figure-of-eight condenser elements to deliver crisp, clear, and well-balanced stereo response. The included AT8547 power module allows users to select wide left-right stereo, narrow left-right stereo, or discrete mid-side output for later adjustment in postproduction. This MS design helps capture natural depth while maintaining excellent mono compatibility, making it especially useful when audio may be edited, mixed, or collapsed into mono for broadcast and video workflows.\u003c\/p\u003e\n\n\u003cp\u003eThe BP350ST-UL is built for flexible camera and rig mounting. Its permanently attached microphone cable connects to the AT8547 power module, and the included AT8495 mount clip secures the microphone to the module while allowing angle adjustment around other camera peripherals. The power module can be placed in a camera microphone mount or secured with compatible third-party mounting hardware. For connection to camera stereo inputs or traditional microphone preamps, the system includes a 1.2' TA5F to dual-XLR3-M stereo output cable.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for professional field use, the BP350ST-UL includes a switchable 80 Hz high-pass filter to help reduce unwanted low-frequency ambient noise. The package also includes an AT8180 foam windscreen, AT8495 mount clip, O-rings, microphone cable, and hard shell carry case for transport and protection. With high SPL handling, compact construction, and flexible stereo mode control, the BP350ST-UL provides a versatile stereo shotgun solution for demanding broadcast and production environments.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSmall-format MS stereo shotgun microphone designed for broadcast, production, and field recording\u003c\/li\u003e\n  \u003cli\u003e6.3\" camera-mount shotgun design is ideal for ENG, vlogging, and run-and-gun filmmaking\u003c\/li\u003e\n  \u003cli\u003eInterference tube helps reject off-axis noise and focus on distant sound sources\u003c\/li\u003e\n  \u003cli\u003eIndependent line-cardioid and figure-of-eight condenser elements\u003c\/li\u003e\n  \u003cli\u003eMid-side stereo configuration provides natural stereo imaging and strong mono compatibility\u003c\/li\u003e\n  \u003cli\u003eSwitch-selectable stereo modes include wide left-right, narrow left-right, and discrete mid-side output\u003c\/li\u003e\n  \u003cli\u003eExcellent channel separation and natural response, even at high SPL levels\u003c\/li\u003e\n  \u003cli\u003eIncluded AT8547 power module provides mode selection and switchable 80 Hz high-pass filter\u003c\/li\u003e\n  \u003cli\u003eAT8495 mount clip secures the microphone to the power module and allows flexible angle placement\u003c\/li\u003e\n  \u003cli\u003ePower module can be mounted into a camera microphone mount or secured with third-party mounting hardware\u003c\/li\u003e\n  \u003cli\u003eCompatible with most ATM350a mounts and mounting systems, available separately\u003c\/li\u003e\n  \u003cli\u003eIncludes stereo output cable, windscreen, mount clip, O-rings, microphone cable, and hard shell carry case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\n\u003ch3\u003eMicrophone\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMicrophone Type\u003c\/strong\u003e: Boundary \/ Broadcast Array \/ Shotgun (Stereo)\u003cbr\u003e\n\u003cstrong\u003eElement Type\u003c\/strong\u003e: 2x Condenser;
