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 large-
diaphragm 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
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.
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 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.
