Church Tour Audio Guide System

Influencing factors of the signal and the coverage factor System parameters: 1) The stronger the output power of the transmitter, the greater the coverage of the transmitted signal, the farther the communication distance. But the transmission power can not be too large, the transmission power is too large, not only power consumption, affect the life of the amplifier components, and strong interference, affecting the call effect of others, but also produce radiation pollution. The radio power management agencies of various countries have clearly defined the transmission power of the communication equipment. 2) The higher the reception sensitivity of the communication machine, the farther the communication distance. Envirnmental factor: Environmental factors are mainly path, the density of trees, the environment of electromagnetic interference, buildings, weather conditions and terrain differences. These factors and other parameters directly affect the field strength and coverage of the signal. Other influencing factors: 1) the battery is low, when the battery power is low, the call quality will be worse. Serious, there will be noise, affecting the normal call. 2) antenna matching, antenna frequency band and the machine frequency is inconsistent, the antenna impedance does not match, will seriously affect the call distance. For the user, the antenna should be used to pay attention to tighten the antenna, the other can not just use the non-manufacturers to provide the antenna, can not use the antenna does not meet the frequency of the machine. 3) sound quality depends mainly on the pre-emphasis and de-emphasis circuit, there are more advanced voice processing circuit "voice compression circuit and low-level expansion of the circuit application", which for fidelity voice has a very good effect. 4) The factors that affect the distance and effect of the radio are also related to the season, summer is better than winter. wireless conference system.jpg If you are looking for the church tour audio guide system, Rich Technology must be your best choice.
