main features
The COTT-C2 embedded riot proof microphone is designed specifically for synchronous monitoring and recording of interrogation systems in the prison industry.
Adopting a metal streamline structure design and high-strength aluminum alloy spacing technology to reduce unnecessary air vibrations.
KaBoni silver plated capacitor microphone head, high fidelity, high sensitivity, and low noise within 10-30 square meters.
Eliminating external electromagnetic interference, it has the advantages of strong adhesion, not easy to fade, not easy to oxidize, and hidden installation.
Equipped with a high pass filtering noise reduction circuit, effectively reducing high and low frequency noise in the environment and circuit.
Built in AGC digital speech noise reduction signal processing circuit, effectively preventing speech signal distortion and attenuation.
Equipped with an ALC microprocessor chip control circuit, it automatically suppresses high-intensity sounds and reliably protects backend audio monitoring equipment.
The microphone is equipped with lightning protection, power polarity reverse protection, electrostatic protection, and power protection modules.
Ultra long audio signal transmission technology, using RVVP3 × 0.5mm2 shielded cable to transmit 3 kilometers without distortion.
Suitable for working in ultra high ambient temperatures ranging from -25 ℃ to 70 ℃, ensuring high-quality recording performance in the backend.
Integrated professional pre audio amplification circuit, directly driving active speakers, hard disk recorders, headphones, and more.
Suitable for synchronous monitoring and recording in small rooms such as prisons, drug rehabilitation centers, labor camps, and detention centers.
Compliant with RoHS specifications, the structure does not contain hazardous substances prohibited by the European Union.
● Passed the EU CE standard, the US FCC certification, and the highest inspection synchronous recording and video system construction specifications.
