Product description
1. The system realizes the expansion of more conference functions such as conference basic discussion
2. Fully combine advanced digital technology, network technology and audio technology.
3. Cat6e is uniformly used between the host and the microphone, and between the microphone and the microphone to realize the high-speed transmission of data under the condition of high bandwidth, so as to further improve the reduction of the microphone and the transmission speed of sound, reduce the sound loss, and ensure the high fidelity audio of the microphone sound color
4. At the same time, the shielding system and equalizer module are used together with digital frequency shift technology and suppression technology to control whistling, immune to high-frequency noise, environmental noise and electromagnetic interference, so as to present perfect sound quality to users.
5. It can be seamlessly connected with intelligent central control system and video conference system to provide a complete solution for efficient modern conference system engineering.
