The 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 EC05X5F3M (formally known as K-1504) cable should be used when connecting the ECM-680S stereo shotgun with camcorders having two 3-pin XLR inputs.
The ECM-680S uses the Mid-Side (MS) technique that offers natural stereo sound and excellent localization. Equipped with newly developed large diaphragm microphone capsules with bi-directional characteristics, the ECM-680S delivers superb sensitivity and extremely low inherent noise.
Stereo and Monaural Switchable
The ECM-680S can operate in either stereo or monaural (uni-directional) mode, allowing it to be used in both EFP and ENG applications. Stereo mode is ideal for capturing environmental sound with natural sound quality, while monaural mode is ideal for clearly capturing voice and sound from a distance. These modes can be selected from the switch on the microphone or from compatible Sony professional camcorders. The LED on the microphone lights up when the ECM-680S is set to stereo mode, to easily notify the user that operating mode is currently selected.
Flat-and-Wide Frequency Response
The ECM-680S microphone has a flat-and wide frequency response (50 Hz to 20 kHz (stereo)/40 Hz to 20 kHz (monaural)) in both stereo and monaural modes, and will provide sound reproduction that is extremely smooth and natural.
Built-in Low Cut Filter
The built-in two-position (M,V) low cut switch provides a simple method of reducing the effects of undesired ambient noise.
Compact and Lightweight Design
The ECM-680S has been designed to be a compact yet high-performance stereo shotgun microphone, ideal for camera mounted use. It measures only 9 7/8 inches in length and weighs less than 4.9 oz, maintaining good balance and mobility.
