Product introduction

HP-DK100 omnidirectional microphone adopts intelligent digital FPGA dual-core wide dynamic noise reduction algorithm, which can clearly pick up sounds in complex environments, suitable for video conferences, control rooms, conferences, etc.

Detailed introduction

HP-DK100 Omnidirectional Microphone Product Features:

1: HP-DK100 is a full duplex omnidirectional microphone, suitable for video conferencing, control rooms, conferences, etc.
2: Built-in audio acquisition module, which can provide microphone signals closer to human voice for video conference terminals
3: Built-in KaBoni advanced digital noise reduction microphone, can realize voice intercom within 3 meters, no echo howling
4: The use of advanced digital AEC audio technology independently developed by SIZHENG can completely eliminate echo
5: Using intelligent digital FPGA dual-core wide dynamic noise reduction algorithm, can clearly pick up sounds in complex environments
6: The frequency response range meets the requirements for enhanced voice and audio bandwidth, and meets the audio bandwidth standards supported by video conference transmission
7: ATDA dynamic noise level detection, adaptive band-pass filtering, can effectively suppress room environmental noise and system noise
8: True full-duplex audio, enabling speaking and listening at the same time, maintaining continuity of conference voice during the conference
9: Easy to operate, there is a mute / on mode on the top of the product, which can easily switch the mode of conference voice intercom
10: product plug and play, USB power supply, USB audio transmission, 3.5 connector can be connected to high-power speakers
11: Users don't need to hold the MIC or face the MIC to have a relatively easy voice communication
12: Expansion can be expanded through the cascade (optional) of the product, which can make the product suitable for larger room applications
13: HP-DK100 omnidirectional microphone adopts die-casting sturdy alloy casing and double-layer metal mesh cover design with exquisite appearance.
14: The bottom of the product uses non-slip silicone foam, which can reduce the impact of desktop vibration on the microphone
15: It is suitable for working in the super strong ambient temperature of -20 ℃ ~ 75 ℃ to ensure the high-quality voice intercom effect.
16: Passed the EU environmental protection ROHS directive 2002/95 / EC construction code
17: Passed the European CE standard and the Zui high inspection synchronous recording and video recording system construction specification
18: Passed the FCC related standards test and the corresponding system construction specifications
