The MXL FR-310 video mic delivers sound that's as focused as the video. Mount it onto your camcorder or DSLR camera and you'll cut to tighter cleaner sound recordings. The FR-310 shuts out sound from the sides and back with a pickup pattern that targets sound in front of the camera. Three gain settings pull in the right amount of sound in close-up or long shot situations while a bass roll-off switch leaves low-frequency noise on the cutting-room floor. The integrated windscreen helps block wind noise which aids in keeping your sound in the picture
