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: How to ensure the stability of sound transmission in a wired conference microphone system?
A: Try to use a wired network environment to avoid the wireless network being affected by the environment and affecting the sound transmission effect. For example, in a network conference room, you can use the speaking mode that comes with the conference system, such as the speaker granting everyone a speaking mode, or the participants in the system apply to the chairman to speak, and you can mute other people to reduce the impact of network instability on the meeting.
If participants use laptops or desktop personal computers to attend the meeting, it is recommended to wear headphones or use professional microphones as much as possible. For people in large conference rooms, it is recommended to use professional conference omnidirectional microphones, or to increase the distance between ordinary conference microphones and speakers and make their directions form an eight-shaped shape to reduce the interference of sound transmission in and out. For people who go out to attend meetings using computers, it is ideal to use headphones (ordinary headphones or Bluetooth headphones). If there are special circumstances where you do not bring headphones and can only use external audio, you can mute yourself.
Check and optimize network connections, and try to use Ethernet wired connections instead of Wi-Fi to reduce network interference and improve stability. At the same time, close other network applications to avoid background applications occupying network resources.
