The introduction

       The frequency response is specially designed according to the phonetic feature. The sound quality of the medium frequency region is bright and the bass frequency attenuation can be used to make full use of the neighbor effect. The uniform heart-shaped orientation can effectively enhance the main sound source, while minimizing the background noise, and the microphone is equipped with an anti-fracture 180 degree rotating vertical microphone adapter. The pneumatic damping microphone support can reduce the noise generated by holding the microphone, and the high efficient screen structure of the built-in circular anti-wind noise and detonation is strong and reliable and durable.

Technical indicators

Type: mobile phone.
Directivity: heart type.
Frequency response: 50Hz--15KHz.
Output level (1000 hz)
· open circuit: -54.5dBV/pa (1.85mV)
Output impedance: the rated impedance is 150 ohms (actually 300 ohms) when connected with the microphone's low impedance input.
Phase: when applying positive pressure to the diaphragm, the 2 pin is the positive voltage relative to the 3.
Microphone connection: three-pin special sound plug (XLR positive plug for maximum conductivity)
