A complete wireless omnidirectional microphone system consisting of a main unit 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 microphones can be used for local sound reinforcement through the omnidirectional microphone's speaker. It supports simultaneous USB wired and wireless connection to a PC, with low latency, high fidelity, and intelligent dual-mode switching. The wireless expansion design 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. Within 2.5 meters, both parties can speak simultaneously without lag 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 and broadcasting, live streaming, telemedicine, and other fields.
Instructions:
1. Connect to PC:
2. Insert the wireless receiver into the PC's USB port, long-press the power button on the omnidirectional microphone to turn it on. The wireless receiver and omnidirectional microphone will connect automatically, and then the blue light will stay on.
