The Sony ECM-678 is an electret condenser-type shotgun 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.
With its high performance and durability, the ECM-678 microphone is the perfect choice
for quality-critical sound-acquisition applications.
