The Sony ECM-680S is an MS stereo shotgun, electret condenser microphone, ideal for a broad range of field production and broadcast studio applications. Incorporating newly developed microphone capsules, the ECM-680S offers excellent sensitivity, low inherent noise and a flat-and-wide frequency response. The most distinguished feature of the ECM-680S is its 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 MS microphone signal of the ECM-680S is internally decoded and it provides L and R (stereo) outputs. The ECM-680S is supplied with a XLR-5-pin to XLR-5 pin cable for use with 5-pin XLR input equipped camcorders. The optional K-1504 cable should be used when connecting the ECM-680S stereo shotgun with camcorders having two 3-pin XLR inputs.
