Product Details
main features
COTT-QD35 advanced professional environmental sound digital monitoring probe, pinhole design, concealed installation.
Advanced resin material "honeycomb sound collection" design, completely eliminating "hissing" electronic noise.
Panasonic customized fully directional capacitive microphone with high sensitivity, high bandwidth, and low noise within 5-50 square meters.
Adopting the principle of "Temple of Heaven Echo Wall", the 0.8mm pinhole design achieves the best accurate calculation of sound reflection angle.
Built in digital voice processing circuit and microprocessor chip, two-stage dynamic digital noise reduction processing, excellent resistance to environmental noise.
Built in AGC noise reduction signal processing circuit and advanced echo cancellation technology effectively reduce echoes in open rooms.
Equipped with an ALC level control circuit, it automatically suppresses high-intensity sounds and reliably protects the backend audio monitoring equipment.
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.
