Advanced hand-in-hand conference speaking unit

The single-chip microcomputer controls the digital circuit to achieve digital management, automatic video tracking/voting/sign-in scoring/discussion functions.
Combined with the requirements of the acoustic space (sensitivity level, directivity factor, directivity coefficient), it has a patented elongated microphone pickup head, which enables high sound reproduction and a longer pickup distance.
The stable metal material base has a beautiful and fashionable appearance and has obtained national practical and appearance patents.
LCD liquid crystal display shows the on/off status of the microphone.
The screw-lock aviation plug-in XLR connector can more effectively prevent popping sounds caused by poor contact.
Built-in high-fidelity/capacitive cartridge resistant to mobile phone signal interference, with good sound reproduction, high clarity, low noise, and efficient howling suppression function.
Additional functions such as designated speaking, applying for speaking, chairman exclusive, and setting speaking time can be realized through the management software.
The chairman unit can close the representative unit at any time without any restrictions, fully demonstrating the priority to speak.
Built-in high-fidelity Φ75 speaker, mono headphone output, and step-type knob for volume control.
The 315-degree omnidirectional bendable pure copper hose allows users to customize the length of the microphone tube.
When the microphone is turned on, the red working indicator light on the cartridge lights up.
