1. A complete omnidirectional array microphone with built-in 4-array pickup heads and 8W high-power speaker, plus wireless expansion microphones. Supports up to 4 external wireless expansion microphones. The wireless expansion microphones can be used for local sound reinforcement through the omnidirectional array microphone speaker. It can simultaneously connect to a PC via USB wired and wireless connections, with low latency, high fidelity, and intelligent dual-mode switching. Using wireless expansion, it is recommended for meeting 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. 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 the sound is full and comfortable. 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.
