Features:The frequency response is specially designed according to the characteristics of the speech. The medium frequency region is bright and has a bass frequency attenuation, which can make full use of the neighbor effect.Uniform heart-shaped directivity effectively enhances the primary source while minimizing background noise.The microphone is equipped with a 180 degree anti-cracking rotating vertical microphone adapter.The pneumatic damper microphone holder reduces the noise generated by holding microphone.Built-in round wind noise and popping proof high-efficiency filter.The structure is sturdy and dependable.Specifications:Color: BlackMicrophone type: Dynamic microphoneDirectivity: OmnidirectionalFrequency response: 40Hz - 18KHzOutput level: 1000 Hz conditionOpen circuit level: -51.5dBV/pa (2.6mV)Output impedance: Rated impedance is 150 ohms (actually 290 ohms) when connected to the microphone's low impedance inputPhase: When a positive pressure is applied to the diaphragm, the 2nd pin is positive voltage with respect to the 3rd pin.Size: Microphone length approx. 20 cm / 7.9 in, diameter approx. 5 cm / 2 inWeight: Approx. 225 gPackage Include:1 * Handheld Microphone.
