Sony has introduced its new ECM-B10 compact shotgun microphone, which uses beamforming technology to digitally process the sound signals captured by the four high-performance microphone capsules. This allows users to select the sensitivity with which the microphone picks up sound from different directions, tailoring the recording to their specific needs. Because the ECM-B10 combines three selectable polar patterns in a single microphone, users can easily switch between superdirectional, unidirectional, and omnidirectional directivity.
When super-directional polar pattern is selected, the microphone picks up sound coming directly from the front while minimizing noise from other directions. This option is suitable for interviews, selfie recordings, and other situations where narrow sounds coming from the front need to be recorded. Furthermore, the ECM-B10 supports unidirectional directivity to capture sound coming from the front while minimizing sound coming from behind, suitable for situations where, for example, conversations between several people are recorded. Thirdly, an omnidirectional polar pattern can also be selected, in which sounds from all directions are captured with equal strength - ideal for recording ambient noise.
The Sony ECM-B10 effectively minimizes unwanted noise using its internal digital signal processing to capture sound more clearly. It connects to cameras equipped with an MI (Multi Interface) accessory shoe: either via the analog interface or, for compatible cameras, via the digital audio interface1 to transmit audio signals in digital form directly to the camera without quality loss. Designed to suppress shock and vibration, the microphone design is intended to minimize low-frequency vibration noise.
Because the Sony ECM-B10 attaches easily to the MI shoe of a compatible camera, no additional cables are required, simplifying setup. The microphone is powered directly from the camera, so filmmakers don&t have to worry about dead microphone batteries. Since no connecting cables are needed, no unwanted noise is transmitted to the microphone via cables. Since the ECM-B10 is dust and moisture resistant and has an included windscreen, it can be used for outdoor shooting by combining it with a camera body and lens that are also dust and moisture resistant.
Various adjustments to audio settings can be made using several switches on the back of the microphone. The ECM-B10 offers the following audio adjustment options:
- ATT (Attenuator) switch (0/10/20 dB).
- FILTER switch (Noise Cut/Low Cut/Off).
- AUDIO LEVEL control with AUTO/MAN (manual) switch
- DIGITAL/ANALOG switch
