Shotgun Microphone  

The Sony ECM-678 is a short shotgun, electret condenser-type microphone, which delivers outstanding sound performance in all field production and broadcast studio applications. It is also well-suited for use on Sony professional camcorders such as the HDV Series, DVCAM Series, and XDCAM Series. The ECM-678 offers excellent sensitivity, low inherent noise, and extreme durability. Its highly directional response allows clear voice pick-up even in the most demanding of environments, while the built-in low-cut filter switch helps to reduce unwanted pop and wind noise encountered in the field.
