The conference system can be seen in scenes such as government reception, factory visits, product observations, tour guides, exhibition explanations, visits and teaching, training explanations, conference speeches, etc. It is comfortable to wear, good sound, low noise, good performance, and easy to replace traditional speakers position.
The audio problems of the conference system mainly include loud noise, local sound howling, power interference, etc. Common audio problems in the conference system include:
1、loud voice. It will affect the clarity of the sound and the brightness of the sound, and sometimes the sound of the venue will not be heard at all. Due to excessive gain, automatic gain control and impedance mismatch, background noise will be generated.
2、The local voice howls. Failure to properly place microphones and speakers in the layout of the conference room may cause the sound of the speakers to be fed back to the microphones, forming a positive feedback circuit between the speakers and the microphones.
3、Power interference. Poor grounding of the power supply, poor grounding contact, impedance mismatch between equipment, and unpurified equipment power supply will cause clutter interference to the audio signal, resulting in low-frequency AC hum.
The conference system, in the tourism industry, is called a tour guide system, tour guide audio equipment, and travel equipment. Rich Age, as a conference audio equipment, has its unique advantages, which can effectively avoid many problems with the audio effects of the conference system. It uses UHF frequency band, with strong anti-interference ability, multiple channels, dedicated frequency channels, multiple teams will not be affected, and cross-frequency will not occur. Signals such as mobile phones and WiFi will not interfere with the normal use of the conference system. The noise can be effectively reduced, and there is almost no howling.
