Three directivity modesAdvanced 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 micEight 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 99.3 mm in length.Great sound with low noiseWhen 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.Cable-free connectionSimply 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.Mechanical noise suppressionAn advanced shock and vibration suppressing design effectively minimizes 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 soundA 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.Essential controlsRecord 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. This level of control can contribute to smooth, stress-free post production.Wind screen suppliedThe ECM-B1M is supplied with a fur type wind screen that can reduce wind noise when shooting outdoors.
