COTT-QD50 hemispherical microphone
Pick up area: 5-150 square meters (adjustable) Directional characteristics: Full directional sensitivity:- 35dB microphone: high fidelity silver plate
Product details
main features
The COTT-QD50 hemispherical microphone 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 a cross shaped anti swirl sound hole, its internal resonant sound chamber has been accurately calculated, resulting in clearer sound reception.
Adopting a honeycomb shape can eliminate reflective phase distortion, suppress echo, and provide 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.
High fidelity silver plated diaphragm capacitor microphone, with high fidelity, high sensitivity, and low noise within 5-150 square meters.
Built in AGC and DTS noise reduction signal microprocessor circuit, automatically adjusts high-intensity sound and instantaneous impact sound.
The uniquely designed "electronic noise dynamic closed-loop suppression circuit" completely eliminates "hissing" electronic noise.
The microphone is equipped with built-in 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
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.
Certified according to the IAF UKAS international quality management system standard ISO9001:2008.
