MS Stereo Shotgun Electret Condenser Microphone

The ECM-680S is an MS stereo* shotgun, electret condenser-type microphone, ideal for a broad range of field production and broadcast studio applications. It offers excellent sensitivity, low inherent noise, and a flat-and wide frequency response and is switchable operation between a highly directional monaural mode and stereo mode.

Monaural mode provides highly directional sound pickup, while stereo mode delivers natural and spatial sound. The ECM-680S is compact and lightweight, making it well-suited to use with a range of Sony professional camcorders. In addition, it can be mounted on a boom pole for more versatility. With its excellent quality and versatility, the ECM-680S is an ideal choice for quality-conscious sound gathering applications.

* MS microphone signal of the ECM- 680S is internally decoded to L and R (stereo) outputs
