The site is about 5,000 square meters, which can accommodate more than 2,000 people. The audio console is placed at the end of the auditorium.
It means that the site area is large and the distance is far. There are more than 2,000 mobile phone interference signals, and the frequency stability of the wireless microphone is required to be excellent, so that the mutual interference can be reduced to a low level.
What is frequency stability? An important parameter for measuring the quality of wireless microphone communication. It involves a lot of research and development issues related to wireless technology (the influence of phase noise of the frequency source on the receiver sensitivity and selectivity of the receiver, the impact on the high-speed digital communication system, the impact on the test system test sensitivity, etc.).
We simplify the understanding of the accuracy between the received signal and the transmitted signal.
