The ECM-B10 converts analog sound to digital within the microphone body and performs digital signal processing using Sony's unique algorithms—enabling three directional pickup patterns as well as noise reduction. In-body digital conversion also helps to reduce noise inside the microphone.
Direct digital audio transmission to the camera eliminates signal degradation, supplying pristine in-camera audio recordings without the noise and hiss common to analog preamps found in many cameras.
A simple Digital/Analog switch also provides compatibility with a wide range of cameras using an analog interface. The ECM-B10 is compatible with a7R IV, a7C, ZVE10 cameras and other Sony products with MI (Multi-interface shoe) that support digital audio.
