High-quality microphone capsules for clear voice recording
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.
Noise-suppressing filter functions
A noise-cut filter uses digital signal processing to effectively remove annoying persistent background noise, for clear recording. A low-cut filter on the microphone side also reduces unwanted low-frequency sound from wind, air conditioning, and vibration. Less noise removal is needed post-production, making workflow more efficient.
Three selectable directivities
Three directivity options are available. Uni-directional is ideal for use in indoor environments, reducing the capture of sound reflected from walls; Omni-directional allows recording to include ambient and environmental sounds; and Stereo provides a sense of presence and high sound quality. 
Audio monitoring possible
When recording via a USB connection to a PC or smartphone, audio can be monitored before transmission to the external device by connecting commercially available headphones directly to the microphone. 
Operability enables real-time monitoring and adjustment
During sound collection, the microphone volume can be adjusted with the AUDIO LEVEL (upper) dial while checking the audio input level in real time with the LEDs. The headphone volume and the volume ratio between the microphone and the PC can be adjusted with the lower dial when a wired connection is used, and by pressing the dial, the mix of microphone input audio and device audio can be adjusted in steps. When the wireless connection is in use, the LINK lamps on the microphone and receiver can be used to check the connection status for recording.
