Features
● Complies with international standards IEC60914 and GBT15381-94.
● Patented exterior design, overall high-end and dignified, in line with modern aesthetic standards.
● Professional high fidelity capacitor microphone with sensitive pickup and clear voice, with a bandwidth of 20Hz~20KHz.
● Adopting anti-interference circuit design can prevent interference from electronic products such as mobile phones.
● The microphone head is equipped with a speaking light circle, which can display the unit's speaking and off status.
● Speech switch button with transparent speech pattern, constantly lit during speech.
● The unit is a passive device powered by the system host. The input voltage is 24V, which is within the safe range.
● The unit is connected by a 1.5M*2M T-type 8-core wire and a Category 6 network cable. The wire is shielded with aluminum foil and waterline, which greatly reduces the interference of strong electromagnetic waves on the wire.
● The microphone unit is equipped with a speaker, and the volume is adjusted by the microphone itself.
● It comes with a 1.77-inch screen, and the display screen has clock, ID code, speaker volume, microphone switch icon and other displays.
● With audio start function, the microphone unit power is automatically turned on when speaking.
● It supports multiple chairman units, which can be installed arbitrarily without position restrictions when connected. It has a priority function of fully controlling the order of the meeting and can control the atmosphere of the meeting.
● The "hand in hand" cable series connection mode is easy to install and maintain.

Q: What features should a best conference table microphone have?
A: Environmental noise immunity: It can effectively reduce the interference of environmental noise and improve speech clarity.
Natural sound: Make the speech of participants sound natural, improve the comfort and effect of the meeting.
Bright, clear and moderate loudness: Let the sound achieve good effect in the conference room, which is clear and does not produce howling.
Wide and flat frequency response range: The ideal conference microphone frequency response range should be wide, covering the main frequency range of human speech (generally around 80Hz - 12kHz).
Q: How does the placement of the best conference table microphone affect its performance?
A: When the microphone is placed on the desktop, the intersection angle and distance between the speaker's lips and the microphone core should be noted. The core axis of the microphone should be directed towards the speaker's lips to achieve a better frequency response characteristic. If the speaker's lips deviate from the central axis, the frequency response characteristic will be worse, with more severe high-frequency loss and a reduction in the output voltage of the microphone.
