ECM-680S
Electret Condenser Microphone

OUTLINE

The Sony ECM-680S is an MS stereo* shotgun, electret condenser-type 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 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.

FEATURES

Excellent Sound Quality
The ECM-680S uses the Mid-Side (MS) technique that offers natural stereo sound and excellent localization. Equipped with newly developed largediaphragm microphone capsules with bi-directional characteristics, the ECM-680S delivers a superb sensitivity of -28 dB* (stereo)/-32 dB* (monaural), and extremely low inherent noise of less than 20 dB SPL (stereo/monaural).

* 0 dB=1 V/Pa

Flat-and-Wide Frequency Response
The ECM-680S microphone has a flat-andwide 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.
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.
* Stereo and monaural modes can be switched from the Sony HDW-F900R CineAlta camcorder, HDW-790 HDCAM camcorder, and PDW-F350/F330 XDCAM HD camcorder.
Compact and Lightweight Design
The ECM-680S has been designed to be a compact yet high-performance stereo shotgun microphone, ideal for cameramounted use. It measures only 250 mm (9 7/8 inches) in length and weighs less than 140 g (4.9 oz), maintaining good balance and mobility when mounted on a range of Sony professional camcorders.
