Product Details
main features
The COTT-QD40 original sound level 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 the principle of "Temple of Heaven Echo Wall", the 0.8mm 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.
SiZhenG large gold-plated diaphragm capacitor microphone, 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.
Equipped with the latest DNP and DSP digital processing units, it 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.
