1. A complete set comprising an omnidirectional array microphone with built-in 4-array pickup heads and 8W high-power speaker, plus a wireless expansion microphone. Supports up to 4 external wireless expansion microphones. The wireless expansion microphones can be used for local sound reinforcement through the omnidirectional array microphone's speaker. It can simultaneously connect to a PC via USB cable and wireless connection, with low latency, high fidelity, and intelligent dual-mode switching. The wireless expansion approach is recommended for meeting rooms under 60 square meters. Equipped with a professional high-performance DSP processor, it leverages intelligent mixing, full-duplex intercom algorithm, echo cancellation, automatic gain, and intelligent noise reduction algorithms to provide strong algorithmic support for video conferencing calls. Within 2.5 meters, both parties can speak simultaneously without stuttering or dropped words, and the sound is clear, smooth, and natural. The speaker delivers sound with bass, full-bodied and comfortable. It truly achieves easy listening, easy speaking, and no fatigue. Widely used in remote video conferencing, education recording, live streaming, telemedicine, and other fields.
