The Sony ECM-719 is a stereo electret condenser microphone designed for use with small portable recording devices such as MiniDisc and DAT recorders. The microphone features an attached microphone cable that terminates to an L shaped 1/8" (3.5mm) stereo mini-connector. The stereo microphone accurately reproduces signal while maintaining the true stereo imagery of the incoming audio. This makes the ECM-719 a suitable option for recording outdoor ambiance, lectures, performances, etc.

The electret condenser capsule can be powered internally using an LR44 battery or externally when used with compatible recording devices. A Voice / Music switch enables the user to choose the desired character and the small, unobtrusive, lightweight profile is convenient when traveling or recording on location.
