main features
COTT-S2 is designed specifically for synchronous monitoring and recording in classrooms, warehouses, and conference rooms, assembled with original imported kits.
Adopting advanced resin PVC material with a "square lattice surround" design, it effectively collects sound from all directions.
Using KaBoni advanced digital noise cancelling condenser microphone, high fidelity, high sensitivity, and low noise within 10-100 square meters.
The surface of the product is sprayed with a "Nano" diffuse coating, which has high weather resistance and can be installed in the center of the ceiling or on the side wall.
Adopting the "Triangulation" array technology for multi-level dynamic noise reduction processing, comprehensively capturing complete and clear speech sound.
● Integrate professional automatic noise recognition processing technology and AGCANSNoise reduction signal microprocessor circuit.
Equipped with an ALC automatic level control circuit, it automatically suppresses high-intensity sounds and reliably protects the backend audio monitoring equipment.
Built in DSP digital processing unit, in line with the high bandwidth, high linearity, flat and stable response of the digital age.
The microphone is equipped with lightning protection, power polarity reverse protection, ESD protection, and power protection modules.
Ultra long audio signal transmission technology, using RVVP3 × 0.5mm2 shielded cable signal transmission for 3 kilometers without distortion.
Suitable for working in ultra high ambient temperatures ranging from -20 ℃ to 75 ℃, ensuring high-quality recording performance in the backend.
