Product Details

HP-DK200 Video Conference Microphone Supplier Equipment Introduction
1: HP-DK200 isVideo conferencing microphone supplierSuitable for video conferences, control rooms, meetings, etc.
2: Built in audio capture module, capable of providing microphone signals closer to human voice for video conferencing terminals.
3: Built in KaBoni advanced digital noise cancelling microphone, capable of voice intercom within 3 meters without echo whistling.
4: The use of SIZHENG's independently developed digital AEC audio technology can comprehensively eliminate echoes.
5: Adopting intelligent digital FPGA dual core wide dynamic noise reduction algorithm, it can clearly pick up sound in complex environments.
6: The frequency response range meets the requirements of enhanced voice and audio bandwidth, and conforms to the audio bandwidth standards supported by video conferencing transmission.
7: ATDA dynamic noise level detection and adaptive bandpass filtering can effectively suppress room environment noise and system noise.
8: True full duplex sound effects enable simultaneous speaking and listening, maintaining the coherence of conference speech during the meeting.
9: Easy to operate, the product has a */on mode on the face, which can adjust the volume of the built-in speaker or connect an external speaker.
10: The product is plug and play, no need to install any devices, USB bus power supply and audio transmission.
11: Users can have relatively easy voice communication without holding or facing the MIC.
12: Expansion can be achieved through cascading (optional) expansion of the product, making it suitable for larger room applications.
13: The product can be connected to a PC via USB for multiple purposes, including IP voice, network voice chat, web conference rooms, etc.
14: By linking the audio function module, it is possible to achieve high-quality results in video conferencing with machines, hardware, and other devices.
15: Suitable for working in ambient temperatures ranging from -20 ℃ to 75 ℃, ensuring high-quality voice intercom performance.
16: According to the EU Environmental ROHS Directive 2002/95/EC, construction standards have been established.
17: Through the EU CE standards and the construction specifications for the synchronized audio and video recording system of the Supreme People's Procuratorate.
18: Tested according to relevant standards of the Federal Communications Commission (FCC) and corresponding system construction specifications.
