Professional digital audio discussion conference system meeting microphone Chairman conference microphone system KE-1000A/B

Conferencing system microphone A common problem is howling, howling cause has nothing to do with the microphone,
But its sound amplification system for the microphone tuning gain is too large, popular point is the microphone open large, the system The amplification of the microphone enhances, breaking through the tipping point of its feedback formation self-excited formation.
The causes are as follows:
1, Sound amplification environment is too poor, architectural acoustic design is unreasonable, there is a sound focus problem.
2,speaker layout is unreasonable, the microphone directly to the speaker's sound radiation direction.
The 

3, microphone is too sensitive and too highly directional.
4, System pre-debugging is not good.
| Solutions |
1, through the layout of the space environment (technical personnel who need to understand the principles of architectural acoustics)
2,Replace low sensitivity microphone (relative to reduce pickup distance, pickup effect)
3,through the microphone volume on the amplifier and the total volume interaction from small to large or the gain size of the mixer.

4, suppresses howling through third-party devices, such as feedback suppressors, frequency converters, or equalizers to tuning.
