Sony ECM-680S MS stereo shotgun Electret condenser microphone

The Sony ECM-680S is a professional MS stereo shotgun electret condenser microphone designed for demanding field production and broadcast applications. This versatile microphone features newly developed capsules that deliver high sensitivity, low noise, and a wide frequency response, making it a reliable choice for quality-conscious sound engineers.

Switchable Mono and Stereo Modes

The standout feature of the ECM-680S is its ability to switch between highly directional monaural and spatial stereo modes. Monaural mode is optimized for capturing clear dialogue from a distance, while stereo mode provides a natural soundstage for environmental recording. Users can toggle these modes via a physical switch on the microphone or through compatible Sony professional camcorders.

Superior Sound Quality and MS Technology

Equipped with Mid-Side (MS) technology, the ECM-680S ensures excellent localization and natural stereo imaging. The internal MS signal is decoded to L and R outputs for immediate use. With a sensitivity of -28 dB (stereo) and -32 dB (monaural), plus an inherent noise level of less than 20 dB SPL, it captures pristine audio even in quiet environments.

Compact and Lightweight Build

Designed for mobility, the ECM-680S measures just 250 mm in length and weighs less than 140 g. This compact form factor maintains the balance of camera-mounted setups and is equally effective when used on a boom pole. An integrated LED indicator provides immediate visual confirmation when stereo mode is active.

Compatibility and Technical Notes

The ECM-680S offers a flat frequency response of 50 Hz to 20 kHz in stereo and 40 Hz to 20 kHz in monaural. Remote mode switching is supported on specific models including the Sony HDW-F900R CineAlta, HDW-790 HDCAM, and PDW-F350/F330 XDCAM HD camcorders.
