Teleconferencing refers to providing conferences for the venue

Directional conference microphone signal input interface, using high-quality microphone signal amplifier and automatic gain adjustment technology, the speaker does not have to be close to the microphone to speak; through the directional conference microphone acquisition, the ambient noise is completely filtered, clear, stable, loud, real, completely Solve the problem of empty voice in conference calls. Speaker signal output interface can be connected to active speakers or amplifiers, providing first-class comfortable listening experience. If the venue is very large or the number of participants is large, or other equipment cannot meet your requirements, or you are seeking the best conference results, you will be satisfied with the results. Using unique digital signal processing technology, it provides a perfect full-duplex call at the venue solution.

Full-duplex call: Innovative technology is used to ensure the full-duplex call performance between this site and other sites, without any voice interruption or disconnection.

Echo Cancellation: The system's excellent echo cancellation technology guarantees the effect of telephone conversation and completely eliminates the howling (howling) phenomenon between the microphone and the speaker. Spatial reflection sound cancellation; provides the clearest sound collection effect.

Automatic gain adjustment: The microphone amplifier circuit uses automatic gain adjustment technology. The speaker is farther or closer to the microphone, and there is no significant change in the volume transmitted to the other party. Can use the built-in microphone and speakers for meetings, no need for conference microphones and active speakers, can be directly connected to conference microphones and active speakers can be connected to the conference room audio system (mixer, amplifier, conference microphone, etc.), unlimited microphone , Record unlimited time conference calls through the recording interface, dial directly into the conference call.
