बैठक कक्ष स्पीकर प्रणाली के लिए सामान्य हस्तक्षेप
ट्रांसमिशन के दौरान ऑडियो सिग्नल द्वारा उत्पन्न हस्तक्षेप कई गुना है। आमतौर पर, इसमें शक्ति हस्तक्षेप, अंतर-डिवाइस हस्तक्षेप, प्रकाश हस्तक्षेप, आदि शामिल हैं। शक्ति हस्तक्षेपः यह खराब पावर ग्राउंडिंग, खराब ग्राउंड संपर्क और उपकरण के बीच प्रतिबाधा बेमेल, "शुद्धिकरण" के बिना बिजली की आपूर्ति, ऑडियो लाइन और एक समान पाइप के कारण होता है, एक ही चैनल या पुल फ्रेम वे सभी ऑडियो सिग्नल के लिए क्लैटर हस्तक्षेप का उत्पादन करेंगे, जो कम-आवृत्ति एसी "बुज़निंग" ध्वनि बनाते हैं।
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.
