HS Series Desktop Interface Type Pickup Open Counter Synchronous Monitoring and Recording

Product Description:

1. Desktop The interface type microphone is designed for synchronous monitoring and recording in open counters and office environments.

2. Adopting gold-plated capacitor microphone head, high fidelity, high sensitivity, high bandwidth, and low noise within 5-50 square meters.

3. Adopting a 0.8mm pinhole design, its internal resonant cavity has been accurately calculated, resulting in clearer sound reception.

4. Adaptive dynamic noise reduction processing, built-in high-speed DSP digital signal processor, two-stage dynamic noise reduction processing.

5. Equipped with a unique electronic noise dynamic closed-loop suppression circuit, it completely eliminates the "hissing" electronic noise.

6. Built in ALC level control circuit, automatically adjusts the high and low intensity of voice and instantaneous voltage and current surges.

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

8. Integrated professional audio processor, which can directly drive active speakers, hard disk recorders, tape recorders, etc.

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

10. Passed the EU CE standard and the highest inspection synchronous recording and video system construction specifications.

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

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