Boya BY-VM02 Unidirectional Camera Micrphone for DSLRs Camcorders

Two 1/2 inch condenser capsules with super-cardioid pick up pattern are mounted, focusing on audio in front of camera, while minimizing pickup from the sides and rear An in-built shock mounting system isolates the BY-VM02 capsule and electronics from its standard sized shoe mount, providing isolation from external physical factors that may cause unwanted rumble and vibrations in the microphone.

Microphone uses standard sized shoe mount for on camera use and features 3/8 inch thread in the base of the mount for easy boom pole mounting.

In addition to microphone's native 40Hz to 20kHz response selectable high-pass filter at 80Hz is available, which will prevent low end noise such as air conditioners and traffic from being recorded -10dB and -20dB level attenuation (or PAD), selectable from inside the battery compartment, allows recording of loud sound sources, such as live music or motorsports. Manufactured from rugged and durable ABS, resulting in lightweight and extremely portable.
