Intelligent digital conference system microphone
Functional features:
Comply with iec60914 and gbt15381-94 international standards
Patented design, overall high-grade and solemn, in line with modern aesthetic standards
Professional high fidelity capacitor microphone, sensitive pickup, clear voice, bandwidth up to 20Hz ~ 20kHz
The anti-interference circuit design can prevent the interference of mobile phones and other electronic products.
The microphone head is equipped with a speaking light ring, which can display the speaking and off status of the unit
The speech switch button has a transparent speech pattern, which is always on when speaking
Display screen with LED light
The unit is passive equipment and powered by the system host. The input voltage is 24V, which belongs to the safe range
For the connection of unit network cable, the wire is shielded by aluminum foil and water line, which greatly reduces the interference of strong electromagnetic wave to the wire
The microphone unit is equipped with speaker and headphone output port, and the volume is set by the host.
With audio start function, the power supply of microphone unit will be turned on automatically when speaking.
It supports multiple chairman units. When connected, it is not limited by location, and can be installed arbitrarily. It has the priority function of fully controlling the conference order and controlling the conference atmosphere.
"Hand in hand" cable series connection mode is convenient for installation and maintenance
