The Boya BY-F8C Cardioid Lavalier Video/Instrument Microphone is a Lavalier microphone that can be used for video recording, as well as music recording. The frequency response favours the mid-range frequencies of group performance while minimizing noise registering at high and low frequencies. The omni-directional pattern helps to pick up of sounds from all directions, to make sure all sound is clear, and no details are missed. A foam windshield and a fur windscreen are included to reduce noise and ensure optimal sound quality. The Low-Frequency Roll-Off switch gives you the option to filter out low sound waves.
