Description
The BY-BM3031 On-Camera Supercardioid Shotgun Microphone from BOYA features a three-level gain switch that provides a +20 dB boost, 0 dB, or a -10 dB pad that helps prevent distortion from audio overload when capturing audio. A high-pass filter at 80 Hz rolls-off unwanted low-frequency noise and rumble, which delivers a richer-sound recording. The 3.5mm output mini-jack connector makes it compatible with DSLRs, camcorders, audio recorders, and other devices as well as to capture broadcast-quality recordings that are clear and precise.
