1. A complete system consisting of an omnidirectional array microphone with built-in 4-array pickup microphones and an 8W high-power speaker, plus a wireless expansion microphone. It supports up to 4 wireless expansion microphones. The wireless expansion microphone can be used for local sound reinforcement through the omnidirectional array microphone's speaker. It can simultaneously connect to a PC via USB wired and wireless connections, with low latency, high fidelity, and intelligent dual-mode switching. The wireless expansion approach is recommended for conference rooms under 60 square meters. Equipped with a professional high-performance DSP processor, it provides strong algorithmic support for video conferencing calls based on intelligent mixing, full-duplex intercom algorithm, echo cancellation algorithm, automatic gain algorithm, and intelligent noise reduction algorithm. It ensures that within 2.5 meters, both parties can speak simultaneously without lag or dropped words, and the sound is clear, smooth, and natural. The speaker playback has bass and full, comfortable sound. It truly achieves easy listening, easy speaking, and no fatigue. Widely used in remote video conferencing, education recording and broadcasting, live streaming, telemedicine, and other fields.
