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:How does the automatic mixer improve sound clarity?

It tracks moving speakers by automatically reducing gain on weak signals and increasing gain on strong signals, maintaining constant total gain without acoustic feedback.

Q:What are the two adaptive filter modes available?

The device offers 'Fast' mode for frequent microphone position changes and 'Precise' mode which converges slower to suppress more reverberation components.

Q:Can this device be connected to other conference systems?

Yes, it features AUDIOLINK digital audio cascade interfaces, allowing connection to CLEACON series controllers and cascading to other compatible devices.

Q:What is the maximum additional gain before feedback occurs?

Depending on the acoustic environment and selected mode, an additional gain of up to 12dB can be obtained before acoustic feedback occurs.

Q:Does the auto mixer work in bypass mode?

Yes, even when the feedback suppressor is switched to 'bypass' mode, the automatic mixer function still works.
