The HS series fidelity dynamic microphone is specially designed for public security, procuratorial, judicial, and educational purposes Synchronized monitoring and recording in the financial industry

Product Description:

1. The fidelity dynamic microphone is specially designed for public security, procuratorial, judicial, and educational purposes Designed for synchronous monitoring and recording in the financial industry.

2. CIear speech noise reduction technology prevents radio frequency interference and suppresses noise around the environment.

3. Adopting the HS cross anti swirl sound hole design, its internal resonant sound cavity has been accurately calculated, resulting in clearer sound reception

4. Honeycomb design can eliminate reflective phase distortion, suppress echo, and provide clear and high-quality audio signal output.

5. Authentic dynamic noise reduction silver plated diaphragm capacitor microphone, with high fidelity, high sensitivity, high bandwidth, and low noise within 5-100 square meters.

6. Equipped with HS's unique, it completely eliminates the "hissing" electronic noise

7. The microphone is equipped with lightning protection, power polarity reversal protection, and power protection modules.

8. Ultra long audio signal transmission technology, using RVVP3 × 0.5 mm2 shielded cable to transmit 3 kilometers without distortion.

Working in an ultra high ambient temperature range of 9-25 ℃ to 70 ℃, ensuring high-quality recording performance in the backend.

10. Integrate professional pre audio amplification processing circuits to directly drive active speakers, hard disk recorders, headphones, and more.

11. Passed the EU Environmental ROHS Directive 2002/95/EC construction standards.

12. Passed the EU CE standards and the construction specifications for the highest level synchronous audio and video recording system.

13. Tested according to relevant standards of the Federal Communications Commission (FCC) and corresponding system construction specifications.

14. Certified according to the international quality management system standard ISO9001.
