This product is a high-fidelity pickup that uses a single diaphragm condenser microphone head and a high-fidelity/low-noise processing chip. Its voice is clear and clean with low noise. It has a built-in dedicated audio signal processor that effectively prevents voice signal distortion and attenuation while reducing noise. It has a built-in preamplifier circuit that can directly drive active speakers, hard disk recorders, recorders, etc. The pickup range can reach up to 50 square meters. It contains a dedicated potentiometer for reliable volume adjustment. It has built-in lightning protection, power polarity reverse protection, and electrostatic protection. It is suitable for ceiling or desktop installation and adopts dust and moisture protection technology. It is suitable for classroom recording, conference recording, banks, public security, procuratorial and judicial places.
