The culprit of the conference rollover was found! Hardware is the stability of microphone without noise reduction and algorithm.

What are you most afraid of in a meeting? It's not that the sound quality is unclear, but that the microphone lost its voice at the critical moment, the current noise roared and the equipment restarted for no reason.
Having been deeply involved in the audio and video industry for many years, we found that 80% of conference audio accidents have nothing to do with noise reduction, howling and radio frequency interference, and the root causes of the problems are all hidden in the neglected underlying hardware.
At present, with the sound quality and competition algorithm in the industry, we are deeply cultivating the reliability of basic hardware, holding the last line of defense for conference support, and avoiding sudden failures at the venue from the root.

01 adapt to inferior commercial power, bid farewell to the meeting and lose your voice.
Many old conference rooms and lecture halls of government and enterprises generally have short power supply boards: large fluctuation of commercial power, poor grounding of lines, stage lighting and large-screen equipment generating a large number of power supply harmonics.
Most microphones in the market simplify the power supply circuit, lack protection, and seem to have gorgeous parameters. When encountering a complex power supply environment, noise, crash and random disconnection immediately occur, and the fault tolerance rate at major conferences is extremely low.
In view of the power supply chaos in the venue, the equipment is equipped with four-level integrated power supply protection circuit, which integrates four protection mechanisms: electrostatic protection, surge suppression, anti-reverse connection and low-voltage voltage stabilization. Smooth start-up impulse current, filter commercial power clutter, even if the grounding of the venue is irregular and the voltage is unstable, it still runs smoothly, completely eliminating the sudden loss of voice in the meeting.
Hardware isolates the noise floor and cracks the unsolvable current sound.
Many engineering masters have encountered this difficult problem: the sound quality of the microphone is fine, the noise reduction parameters are full, and as soon as the large screen and paperless equipment are turned on, there will be harsh low-frequency current buzz.
In fact, this is not a radio failure, but a common-mode crosstalk noise caused by the potential difference between the ground wires of the equipment, which cannot be eliminated by any algorithm or mixer.
We adopt the hardware global electrical isolation scheme to physically separate and isolate the three loops of audio, power supply and control, and cut off the coupling interference of equipment; With independent single-point grounding wiring, high-frequency noise of the circuit is isolated. There is no need to install additional audio isolators, which saves the construction cost and eliminates the stubborn noise in the venue with one click.
Strengthen the durable structure and reduce the later operation and maintenance costs.
Microphone buttons, connectors and flexible microphone poles are the most easily worn and the failure rate is the highest. Daily high-frequency meetings, repeated plugging and unplugging, bending adjustment, ordinary microphones are prone to contact oxidation, line breakage and key failure, and the cost of later repair and replacement remains high.
Relying on the engineering durability optimization process, the alloy conductive contacts are upgraded, and the built-in leads are reinforced to withstand tens of thousands of pressing and bending losses; Optimize the dust-proof and oxidation-resistant design of the interface, and use it normally for a long time, so that the performance of the equipment will not be attenuated, greatly reducing the cost of operation and maintenance of government and enterprises and equipment replacement.

At present, the audio industry excessively pursues noise reduction algorithms and beautifies sound quality parameters, but ignores the core hardware foundation.
No matter how good the tuning algorithm is and how transparent the sound quality is, once the power supply is unstable, electrical crosstalk and hardware are aging, everything will return to zero. Stability is the first essence of conference audio.
