main features
The COTT-C7 original sound level pickup is designed specifically for synchronous monitoring and recording in the public, inspection, and legal industries.
Adopting UniGuard Radio Frequency Interference (RFI) shielding technology to prevent radio frequency interference and suppress noise around the environment.
Adopting the principle of "Temple of Heaven Echo Wall", the micro hole design accurately calculates the optimal sound reflection angle.
The use of echo cancellation cavities effectively reduces severe echoes in open rooms, providing clear and high-quality audio signal output.
Adopting Dolby directional logic surround sound system, with built-in high-speed speech processing unit and two-stage dynamic noise reduction processing.
KaBoni large gold-plated diaphragm capacitor microphone, high fidelity, high sensitivity, and low noise within 10-150 square meters.
Built in AGC and DTS noise reduction signal microprocessor circuit, automatically adjusts high-intensity sound and instantaneous impact sound.
Equipped with the latest DNP and DSP digital processing units, it completely eliminates "hissing" electronic noise.
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 of indoor environments such as public security, procuratorial, and judicial interrogation rooms, bidding centers, and school classrooms.
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.
