4-Mic Array Dual Directional Desk Conference Microphone DSP Noise Reduction USB Gooseneck Microphone
4-Mic Array Dual Directional Desk Conference Microphone
This desktop microphone from HAOKAI integrates a 4-mic dual directional independent pickup array with a deformable metal gooseneck and a multifunction metal knob. Advanced DSP and AI noise reduction separate A/B speaker voices at service counters while suppressing off-angle background noise by ≥20dB - a reliable voice capture tool for government service halls, banks, hotels, translation booths, meeting rooms and large display terminals.
Key Features
- 4-Mic Dual Directional Array: Independent bidirectional pickup with ≥60° directivity separates two speakers (A/B role separation) for clear 1-on-1 dialogue recording.
- DSP + AI Noise Reduction: Beam-forming, voice enhancement, noise suppression and AGC algorithms cut background noise by ≥20dB and suppress off-angle voices by ≥12dB SPL.
- Multifunction Metal Knob: Rotate to adjust pickup volume, press once to mute, press again to resume - one-hand operation with LED status feedback.
- Deformable Metal Gooseneck: Flexible positioning keeps the pickup area aimed exactly at the speaker.
- True Plug and Play: USB Audio Class 1.0 with Type-C interface; connects to PC via the included Type-C to USB cable, no driver installation needed.
- Low Power Consumption: USB powered, only 0.5W (5V/100mA max) regular operation.
- Clear Voice in 3m: 48kHz/16bit audio capture with 65dB(A) SNR and -26±1dB sensitivity.
