Product Details
main features
COTT-QD30/S is designed specifically for synchronous recording of interrogation systems in the prison industry, featuring a pinhole design and concealed installation.
Advanced resin material "honeycomb sound collection" design, completely eliminating "hissing" electronic noise.
BOURNS large gold-plated diaphragm microphone head, high fidelity, high sensitivity, high bandwidth, and low noise within 5-50 square meters.
The microphone adopts a 0.8mm pinhole design, and its internal resonant cavity has been accurately calculated for clearer sound reception.
Unique Dolby omnidirectional logic surround sound standard design, built-in high-speed voice DSP processing unit, two-stage dynamic noise reduction processing.
Equipped with an AGC noise reduction signal processing circuit, the concave cavity effectively reduces severe echoes in open rooms.
Built in ALC level control circuit, automatically adjusts the high and low intensity of voice and instantaneous voltage and current surges.
Ultra long audio signal transmission technology, using RVVP3 × 0.5mm2 shielded cable to transmit 3 kilometers without distortion
Integrated professional pre audio amplification circuit, directly driving active speakers, hard disk recorders, headphones, and more.
● Obtained the patent certificate from the China National Intellectual Property Administration of the People's Republic of China.
Obtained the computer software copyright from the National Copyright Administration of the People's Republic of China.
● Passed the EU Environmental ROHS Directive 2002/95/EC construction standards.
● Passed the EU CE standard and the highest inspection synchronous recording and video system construction specifications.
● Tested according to relevant standards of the Federal Communications Commission (FCC) and corresponding system construction specifications.
Tested by the Security and Police Electronic Product Quality Testing Center of the Ministry of Public Security.
