Advanced digital signal processing enables three selectable polar patterns in a single, versatile microphone: super-directional, unidirectional, and omnidirectional. Eight high-performance microphones use a newly developed beamforming algorithm to achieve extremely clear directivity that effectively suppresses off-axis noise. The microphone is surprisingly compact, with a length of only 99.3 mm. When connected via the accessory shoe with multiple interfaces of a compatible camera that has an integrated digital audio interface, the audio signal is transmitted directly to the camera in digital form, eliminating sound loss. A simple switch also allows compatibility with a wide range of cameras via an analogue interface. Simply attach the microphone to the accessory shoe of a compatible camera to provide direct power and audio connectivity without additional cables or batteries.
The multi-interface accessory shoe offers intelligent connectivity and control for a variety of accessories, providing maximum flexibility and mobility when recording with α devices. The modern shock and vibration suppression design effectively minimizes low-frequency or handling noise that can affect audio quality. Since no connecting cables are required, unwanted noises are not transmitted mechanically to the microphone via cables and connectors. A high-pass filter that suppresses infrasound is implemented via digital signal processing, maximizing audio quality during recording and simplifying post-processing. The control of recording levels, the analogue output for compatibility with a wide range of cameras, and a damper for setting the optimum signal level contribute to the versatility of this camera. These comprehensive control options can reduce the amount of post-processing required.
