Sony ECM-B1M Camera-Mount Digital Shotgun Microphone

The Sony ECM-B1M is a compact, camera-mount shotgun microphone made for mobile video creators using Sony cameras with the Multi Interface Shoe. Designed to work with the a7R IV, it utilizes its built-in Digital Audio Interface to provide high-quality audio directly to the camera. Other Sony cameras equipped with the standard Multi Interface Shoe can also use this microphone, with the option for digital or analog output.

The Sony ECM-B1M Digital Shotgun Microphone features eight top-of-the-line microphone capsules and advanced digital signal processing, allowing for a versatile selection of three directivity patterns to suit any filming or recording scenario. With its seamless plug-and-play functionality, this microphone is hassle-free and ready to use straight out of the box, ideal for recording YouTube videos, Facebook Live streams, or conducting interviews no matter where you are – at home, in the studio, or while on-the-go.

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.
