The BOYA BY-V01 is a stereo X/Y condenser microphone, this microphone provides greater control of your audio than the internal mics on DSLR camera, video cameras, or digital recorders. A switch for 90¡ã or 120¡ã pickup patterns allows you to adjust the directivity of the microphone. Compact and lightweight, the BY-V01 attaches to your camera's shoe mount and plugs directly into your camera or portable recorder's microphone input for crisp, clear stereo audio capture. The included windscreen cuts down not only on environmental noise, but on the operational noises of the lens and camera, such as autofocus movement.
