Sony ECM-M1: 4-Capsule Beamforming & 8 Dial-Selectable Polar Pickup Patterns
The Sony ECM-M1 is an ultra-compact digital shotgun microphone (40 × 72.2 × 64.4 mm, weighing just 65 g without its fur wind screen) engineered for Sony Alpha mirrorless and Cinema Line creators in Bangladesh. Using four matched electret condenser capsules and advanced digital beamforming signal processing, the ECM-M1 is the world's first shotgun microphone to provide eight dial-selectable audio pickup modes from a mechanical rear rotary dial: Super-directional (Front), Unidirectional (Front), Omnidirectional, Super-directional (Rear) (ideal for behind-the-camera narration), Super-directional (Front + Rear) (interviews), Super-directional (Front / Rear Separate) (isolated dual tracks), Stereo, and Ultra-directional (tight front target focus).
Cable-Free Multi Interface (MI) Shoe Digital Audio, 4-Channel Backup & Digital Filters
Sliding directly into the Multi Interface (MI) Shoe on compatible Sony cameras, the ECM-M1 operates completely free of external batteries and 3.5mm audio cables—drawing power directly from the camera body while transmitting pure digital audio with zero analog cable hum or AD-conversion noise (when switched to DIGITAL mode; an ANALOG switch position is also provided for legacy MI Shoe bodies). On compatible cameras supporting 4-channel audio, the microphone simultaneously records omnidirectional ambient audio on Channel 3 and a -20 dB attenuated safety track on Channel 4 to prevent clipping during sudden loud sounds. Side-panel switches control a digital Noise Cut (NC) filter, a Low Cut (LC) wind/vibration filter, and a 0 / 10 / 20 dB attenuator.
