main features
The COTT-S20 dual core high fidelity digital directional microphone is designed specifically for environments such as open windows, counters, and certification halls.
Adopting a double-layer metal baking paint mesh cover, equipped with 3M strong adhesive, and a sliding block structure with a hanging tenon design, it can be used for ceiling or window mounting.
Using KaBoni advanced complementary enhanced digital noise cancelling microphone, the sound pickup height is clear at a close range of 1-5 meters.
Single directional pickup mode or dual directional pickup mode can effectively prevent interference from highways, shopping malls, and pedestrian noise.
Adopting the "Triangulation" array technology for multi-level dynamic noise reduction processing, comprehensively capturing complete and clear speech sound.
Integrate professional automatic noise recognition and processing technology with AGC and DTS noise reduction signal microprocessing circuits.
Built in DSP digital processing unit, ALC microprocessor chip control circuit, automatically suppresses high-intensity sound.
The built-in LED work display status light can fully determine whether the microphone is working properly based on the indicator light.
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 -25 ℃ to 75 ℃, ensuring high-quality recording performance in the backend.
Integrated ASIC front-end audio amplification circuit, directly driving active speakers, hard disk recorders, headphones, and more.
Suitable for synchronous monitoring and recording of indoor environments in windows, counters, wealth management rooms, conference rooms, etc.
