The Sony ECM-680 Stereo Shotgun Microphone provides both M/S (Mid-Side) stereo, and mono audio capturing, at the touch of a switch. The electret-condenser, unidirectional (cardioid) ECM-680, features internal M/S decoding for true stereo placement.

In mono mode, the ECM-680 captures audio like a true shotgun microphone, with superb audio rejection and increased range. The wide frequency response, excellent signal-to-noise ratio and wide dynamic range result in pristine audio reproduction. Measuring only 9-inches long, the ECM-680 is an ideal solution for camera mount applications.

In addition, adding an analog audio cable between the microphone and camera may introduce noise to the signal.
