Now there are many styles, many functions, many brands, different prices, different scopes of use, how to choose the audio guide? It's really nerve-racking! Don't worry. This feedback analysis can help you. First, the standard configuration of transmitter, receiver and charging aviation case. The transmitter is used by the narrator to speak, the receiver is used by the visitors to listen, and the charging aviation box is used for charging and storing the transmitter and receiver. Second, the equipment channel should be configured with the quasi 2.4g, so that the signal transmission is more stable. 2.4g transmission channel has confidentiality, anti-eavesdropping, even if the enterprise usually need to hold some important meetings can have good confidentiality.
Third, the transmission range of equipment is large, and the signal is stable, anti-interference. When receiving leaders, enterprises will guide them to visit, which will involve walking. Therefore, the larger the transmission distance of the equipment, the better. The normal range of 150 meters is the appropriate distance, and good magnetic field anti-interference ability is required. Fourth, the battery life is the most important. Some audio guide use for about three or four hours, which is not enough for leaders to visit. Therefore, the audio guide must choose more than 10 hours. It is better to reach 20 hours. The charging speed is of course the faster the better, and the charging time within 1-2 hours is appropriate.
