AI-Powered supplier vetting

SummaryVISSONIC Electronics Ltd. is identified as a China-based manufacturer/factory and group corporation producing audio and video products, including conference microphones and conference systems. The supplier reports ISO 9001, ISO 14001, OHSAS/OHSMS 18001, and GMP certifications, five production lines, 11–20 R&D engineers, 21–30 quality-control staff, and conference-system output of 100,000 pieces. Its stated services include system design, installation, troubleshooting, user training, and technical support. Export activity is documented since 2015, with 51%–70% of sales from exports. Evidence supports production, certification, innovation, and after-sales strengths, while customization, financial credibility, and customer-case depth remain insufficiently established.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and Group Corporation, with a stated Guangzhou manufacturing location and an in-house R&D, production, and sales operation for audio and video products. This directly supports its status as a product manufacturer rather than only a trading company.

CertificationsThe supplier reports OHSAS/OHSMS 18001, ISO 9001, ISO 14001, and GMP certifications. These stated management-system certifications provide explicit evidence of formal quality, environmental, occupational-health, and related operational controls.

After-Sales capabilityThe supplier states that staff support customers throughout system purchase, installation, on-site troubleshooting, and training on equipment use after installation. This is explicit evidence of comprehensive technical and user-support services.

R&D capabilityThe supplier describes itself as a high-tech enterprise with its own brand and dedicated R&D, production, and sales functions, focused on high-performance and innovative audio-video products. It also reports 11–20 years of combined R&D engineer experience, supporting an innovation capability assessment.

Production capacityThe supplier reports five production lines, 21–30 quality-control staff, and conference-system production capacity of 100,000 pieces. These explicit operating metrics support established production capability for conference-system products.

Product Q&A

Q:Does the feedback suppressor require manual debugging?

No, it uses a fully automatic high-speed howling suppression algorithm that is ready to use without debugging.

Q:What is the difference between Fast and Precise modes?

Fast mode is suitable for situations where microphone positions change frequently, while Precise mode converges slower to suppress more reverberation components.

Q:How many microphone inputs does the VIS-FS100-A support?

It supports four microphone inputs and includes a built-in automatic mixer for these inputs.

Q:Can this device be cascaded with other equipment?

Yes, it has AUDIOLINK digital cascade input and output interfaces to connect to conference controllers or other devices.

Q:What is the frequency response range of the device?

The frequency response range is 125Hz to 15kHz.
