Omni-directional Small Diaphragm Pencil Condenser Microphone

The Sony ECM-100N Omni Hi-Res Mic features a newly-developed microphone capsule which picks up a wide frequency range from 20Hz to 50,000Hz. This fits into Sony’s ethos of Hi-Resolution audio products.

The ECM-100N uses a two-part metallic body construction originally used in the famous C-800G studio mic to prevent acoustic vibration and self-noise, resulting in perfectly clear sound.

A Low-Cut filter switch helps eliminate low-frequency noise and proximity effect while a -10dB pad offers extra headroom if it’s needed.


The Sony ECM-100N Omni-Directional Hi-Res Microphone is an Omnidirectional electret condenser microphone ideal for instrument recording in the studio. It’s compatible with Sony High-Resolution Audio and has been equipped with a newly developed microphone capsule to match the performance required to deliver exceptional clarity and frequency response.

The Sony ECM-100N delivers a flat and wide frequency response of 20 to 50,000 Hz and picks up all the raw sound of the instrument and its extended harmonics which would otherwise not be captured. 

  • Excellent Sound Quality

    Newly developed small diaphragm microphone capsule with Omni-directional characteristics realizes clear and transparent sound in ambient and instrument recording.

  • Flat and Wide Frequency Response

    The ECM-100N microphone has a flat and wide frequency response (20 Hz to 50kHz) and provides superb sound reproduction quality for High-Resolution Audio.

  • Noise Elimination Construction

    Two-part metallic body structure originally employed in the C-800G microphone prevents acoustic vibration, resulting in low noise and clear sound.

Low-Cut filter switch helps eliminate low-frequency noise and proximity effect.

A -10dB pad switch on ECM-100U microphone provides added headroom and minimises distortion caused by transient peaks.
