Masalah umum dan solusi untuk sistem Speaker Ruang Pertemuan

1. Interferensi umum untuk sistem pertemuan speaker ruangan

Gangguan yang dihasilkan oleh sinyal audio selama transmisi adalah manifold. Umumnya, ini mencakup interferensi daya, gangguan antar perangkat, gangguan pencahayaan, dll. Gangguan daya: Hal ini disebabkan oleh grounding daya yang buruk, kontak tanah yang buruk dan impedansi kesalahan antara peralatan, catu daya tanpa "pemurnian", jalur audio dan pipa yang sama dengan kabel AC, bingkai saluran atau jembatan yang sama. Mereka semua akan menghasilkan interferensi sinyal audio, membentuk suara AC "buzzing" frekuensi rendah.

2. Solutions for meeting room speaker system

The sound reduction of video conferencing should be based on the theoretical knowledge of acoustics and the flexible adjustment of the mixer and equalizer according to the different actual conditions, processing and beautifying the sound, making up the defects of the sound field, creating an ideal acoustic environment. Adjust the compression limiter appropriately, when the sudden large peak signal is not overloaded and has no distortion at the same time, avoid compression of the limiter for a long time in the compressed state, so that the sound link can achieve the smooth and round effect. For power interference, the following solutions can be taken:

1. Increase the power supply filter, use harmonic circuit to remove harmonics and "purify" the output power.
2. The input and output lines of the signal should be separated from the power supply lines, and can not be arranged in parallel.
3. Using twisted pair power cord, the total flux produced by two conductors is offset. To sum up, to make the video conference better, it is necessary to improve the aesthetic appreciation and artistic accomplishment of the sound, and to conceive and creative the reduction of the sound, so as to improve the artistic expressive force of the sound.
