Eight high-performance mic capsules and advanced digital signal processing provide three selectable directivity patterns in one compact microphone of approximately 99.3mm (4 inch) in length with super-directional pick up; when connected to the Sony Alpha 7R IV (a7R IV) via its Multi Interface Shoe with digital audio interface support, audio is directly transferred to the camera in digital form so that the highest possible quality is achieved without noise or degradation.

Three Directivity Modes

Advanced digital signal processing makes it possible to offer three switchable directivity patterns in one versatile microphone: super-directional, unidirectional, and omnidirectional.

Super-Directivity in a Compact Microphone

Eight high-performance microphone units work with a newly developed beamforming algorithm to provide extremely sharp directivity that effectively rejects off-axis sound. All of this is achieved in a remarkably compact microphone that is only 99.3mm in length.

Great 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 directly transferred to the camera in digital form so that no degradation can occur. A simple switch also provides compatibility with a wide range of cameras using an analogue interface.

Mechanical Noise Suppression

An advanced shock and vibration suppressing design effectively minimises low-frequency, or handling, noise that can degrade audio quality. The absence of connecting cables also means that no noise can be transmitted to the microphone mechanically via cables and connectors.

Effective Filter for Clear Sound

A low-cut filter that cuts out subsonic noise is implemented through digital signal processing, maximising audio quality at the recording stage and thereby reducing the need for complex post processing.

Cable-Free Connection

Simply clip the microphone into the Multi Interface Shoe on a compatible camera for direct power and audio connections without the need for extra cables or batteries. Sony’s Multi Interface Shoe offers intelligent connectivity and control for a variety of accessories, providing maximum flexibility and mobility for α system shooting.

Wind Screen Supplied

The ECM-B1M is supplied with a fur type wind screen that can reduce wind noise when shooting outdoors.

Essential Controls

Record level control, analogue output for compatibility with a wide range of cameras, and an attenuator that makes it easy to set optimum signal levels all add to this microphone’s versatility. This level of control can contribute to smooth, stress-free post production.
