Before building a wireless microphone system, we must first consider the specific situation of the application scenario. The following is an example of one of our clients' projects. This is a large indoor live performance. The performance hall is about 5,000 square meters with about 2,000 spectators. This project required 16 wireless handheld microphones( 10 for the stage performance and 6 for the spare), approximately 10 sets of headphone/lavalier microphones and several in-ear monitors.
