Sony ECM-680S Microphone

Overview
The Sony ECM-680S is a high-performance stereo shotgun microphone that offers superior sound quality through the use of the Mid-Side (MS) technique. It features newly developed large diaphragm microphone capsules with bidirectional characteristics, resulting in a sensitivity of -28 dB (stereo)/-32 dB (monaural) and low inherent noise of less than 20 dB SPL. The microphone also has a switchable mode between stereo and monaural, making it suitable for both EFP and ENG applications. The flat and wide frequency response (50 Hz to 20 kHz in stereo mode and 40 Hz to 20 kHz in monaural mode) ensures natural and smooth sound reproduction. Compact and lightweight, the ECM-680S is designed for camera mounted use and can also be mounted on a boom pole for added versatility.

The most notable feature of the ECM-680S is its ability to switch between highly directional monaural mode and natural-sounding stereo mode. This makes it ideal for a variety of sound gathering applications, including field production and broadcast studio use. The microphone is also compatible with Sony professional camcorders and can be controlled via a switch on the microphone or directly from the camcorder. With its excellent sound quality and versatility, the Sony ECM-680S is a top choice for those in need of a high-quality stereo shotgun microphone.

About the Sony ECM-680S Microphone
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.

Superior Sound Quality
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 bidirectional 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

Mono/Stereo 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

Flat & Wide Frequency Response.
The ECM-680S microphone has a flat-and wide frequency response (50 Hz to 20 kHz (stereo)/40Hz to 20 kHz (monaural)) in both stereo and monaural modes, and will provide sound reproduction that is extremely smooth and natural.

Compact & Lightweight
The ECM-680S has been designed to be a compact yet high-performance stereo shotgun microphone, ideal for camera mounted 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.
