EG series is a capacitive super-cardioid directional microphone with wide frequency response, high-quality sound collection performance, built-in audio coupling transformer, ultra-low output impedance, designed for professional recording, TV broadcasting, conference, court and other high requirements. The EG series is equipped with a 100Hz high-pass filter, which can be attenuated by a flat frequency response curve to below 100Hz. It can reduce the jet sound of the microphone when speaking at close range, and can reduce the wind noise of the air conditioning system in the environment and car engine sound, echo in the room also.
