Sony ECM-B1M Microphone

Sony MICROPHONE ECMB1M

The SONY ECM-B1M is an ultra-compact camera-mount digital shotgun microphone designed for mobile video creators working with SONY cameras equipped with the multi-interface shoe. Launched alongside the a7R IV, which benefits from its built-in digital audio interface, the ECM-B1M can produce its best quality by delivering a digital audio stream directly to the camera via the multi-interface shoe. Other cameras SONY with the standard multi-interface hot shoe can still use the microphone as there is a selectable digital/analog output.

The ECM-B1M is equipped with eight high-performance microphone capsules and advanced digital signal processing, providing three selectable directivity patterns for a wide range of recording and recording situations. The plug-and-play operation makes the microphone easy to use right away: you can immediately start recording your YouTube videos, Facebook Live streams, and interviews at home, in the studio, or on the go.

• Three directivity modes

Advanced digital signal processing enables three switchable directivity patterns: supercardioid, cardioid, and omnidirectional.
Super directivity in a compact micro
Eight high-performance microphone units work with a beamforming algorithm to provide extremely sharp directivity that effectively rejects off-axis sound. All of this is achieved in a remarkably compact microphone of only 3.91" in length.

• Digital sound with low noise

When connected via the multi-interface shoe of a compatible camera that features a built-in digital audio interface, the audio signal is transferred directly to the camera in digital form so that degradation does not occur. A simple switch also provides compatibility with a wide range of cameras that use an analog interface.
Effective controls for clear sound
Recording level control, analog output for compatibility with a wide range of cameras, and an attenuator that makes it easy to set optimal signal levels all add to the versatility of this microphone.
A low-cut filter that eliminates subsonic noise is implemented through digital signal processing, maximizing audio quality at the recording stage and thus reducing the need for complex post-processing.

• Mechanical noise suppression

An advanced shock and vibration suppression design effectively minimizes low-frequency or handling noise, which can degrade audio quality. The absence of connection cables also means that no noise can be transmitted to the microphone mechanically through cables and connectors.
A leather windshield is supplied to help reduce wind noise when shooting outdoors.

• Wireless connection

Simply place the microphone on the multi-interface shoe on a compatible camera for direct power and audio connections without the need for additional cables or batteries. SONY 's multi-interface shoe offers intelligent connectivity and control for a variety of accessories, providing maximum flexibility and mobility.
