Attention: The microphone also requires the purchase of an additional audio cable and lotus connector!
This microphone adopts a high fidelity and low-noise processing chip, which effectively suppresses environmental noise through multiple frequency selection filters. The circuit is carefully designed. Suitable for various monitoring and pickup locations such as banks, prisons, examination centers, shopping malls, and industrial production, it has the advantages of low noise, high fidelity, wide working voltage range, low power consumption, and long transmission distance.
Product Description: Instructions for Use
This product adopts a high fidelity low-noise processing chip, which effectively suppresses environmental noise through multiple frequency selections. The sound is pure, dynamic and powerful, and the built-in automatic gain control (AGC) circuit is carefully designed. Suitable for various pickup locations such as banks, prisons, examination centers, shopping malls, and industrial production, it has the advantages of low noise, high fidelity, wide working voltage range, low power consumption, and long transmission distance. TQ-301 is a new type of sensitivity adjustable microphone, which is the most ideal product for TV monitoring and security systems. It can be used in conjunction with cameras to achieve video and audio synchronization, with a monitoring range of up to 100 square meters.
