DESCRIPTION

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. Released alongside the a7R IV, which benefits from its built-in Digital Audio Interface, the ECM-B1M is able to produce its best quality by delivering a digital audio stream directly to the camera through the Multi Interface Shoe. Other Sony cameras with the standard Multi Interface Shoe can still make use of the microphone as there is a selectable digital/analog output.

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

Compatibility

Digital Audio Sony Alpha a7R IV

Analog Audio Sony cameras equipped with Multi Interface Shoe

Three Directivity Modes

Advanced digital signal processing makes it possible to offer three switchable directivity patterns: supercardioid, cardioid, and omnidirectional.

Super Directivity in a Compact Mic

Eight high-performance microphone units work with a beam-forming 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 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 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 analog interface.

Effective Controls for Clear Sound

Record level control, analog 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.

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

Mechanical Noise Suppression

An advanced shock and vibration suppressing design effectively minimizes low-frequency or handling noise, which 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.

A fur windscreen is supplied to help reduce wind noise when shooting outdoors.

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.
