Despite its compactness and light weight, the ECM-S1 is equipped with three large-diameter (14 mm) microphone capsules that provide clear, high-quality sound recording with a flat frequency response, particularly in the low-mid-range voice band, while suppressing noise. Great sound quality makes a huge contribution to the overall impression made on viewers by well-produced video.

With both wireless and wired connections available, the ECM-S1 portable streaming microphone is a compact and lightweight high-performance unit that provides clear, low-noise, minimum audio delay, high-quality audio for easy recording or live-streaming either indoors or outdoors.

The low intrinsic noise and wide dynamic range of the microphone allow clear capture of even low-level sound. Designed for streaming, the microphone is tuned particularly to capture the rich textures of the human voice near the mouth clearly and naturally.

Three directional sound capture modes are provided: Uni-directional, Omni-directional, and Stereo. A switch on the side of the microphone allows the user to select the appropriate directivity for the current scene or usage situation.

A digital noise cut filter removes persistent background noise, and a low cut filter on the microphone side reduces unwanted low-frequency sound from wind, air conditioning, and vibration. Less noise reduction is needed post-production, improving workflow efficiency.
