The wireless microphone is light and convenient to use. Many people choose to use it when singing. However, its performance is often affected by various factors such as the frequency interference of the surrounding equipment, user error operation and other factors. What are the common problems during use?
1. Can I use two microphones of the same frequency at the same time?
Cannot be used at the same time. Wireless transmission cannot be "mixed" in the air, and even at the same frequency, the receiver cannot mix two transmitted signals. For example, it is impossible for two FM radio stations to transmit signals on the same frequency. Because this will cause confusion and cause audio distortion. All in all, each wireless transmitter should have a separate receiver and its unique frequency.
2. What is the difference between the frequencies of the wireless microphones to avoid interference?
This depends on the situation, but less often requires 4MHz. Here we cannot answer this question definitively, because it involves complex calculations. In general, cheaper wireless systems require a larger frequency gap because their receiver design is simple and there are few options. This limits the number of compatible channels. Higher-priced systems have better filtering performance, and the distance between channels is closer, and the compatible channels increase accordingly. If we say "you don't want to do your own calculations", we must be right. If you need, please contact the manufacturer or agent, they will help you calculate. Most manufacturers have already calculated the compatible frequency of each wireless feature of Xungu, so you don't need to do these tedious mathematical calculations yourself.
3. What is the reason why the microphone cannot be activated?
Check whether the battery power is low or the filling is wrong.
4. UHF is better than VHF, right?
The two frequency bands used for wireless microphones have their own advantages and disadvantages. This is determined by the user of the frequency band, the physical characteristics of the frequency band, and the adjustment limits of the frequency band.
The following are several aspects of UHF superior to VHF:
The UHF band is not "crowded" in the VHF band.
UHF with flexible frequency has a wider application range.
UHF features can provide more compatible systems [For example, Shure LX and SC (VHF band) systems can only provide 12 compatible channels, while Shure's UHF band system can provide more than 100 compatible channels. ]
UHF system has higher power output than VHF, wider frequency shift, better dynamic range, and better signal-to-noise ratio than VHF.
Several aspects of VHF superior to UHF:
The VHF system is cheaper.
VHF has a larger transmitting range under a specified transmitting power.
The propagation of VHF signals, even through non-metallic substances, is the same. VHF has a long wavelength and is not easily absorbed by the human body.
5. Is the UHF system compatible with the VHF system?
Yes, even if the number of compatible VHF systems is large, it can also be compatible with UHF. (But it is not possible to connect the current VHF antenna, VHF splitter, or VHF antenna distribution amplifier of the UHF receiver).
6. What should I do if the signal transmission distance is short and the communication is interrupted?
1) Please check if the antenna is installed correctly.
2) Please check whether the weak battery indicator light is on.
7. The receiver and microphone are turned on,
But what is the reason for no signal reception?
There are two possibilities:
1) If the receiver and microphone are at different frequencies, please change either to the same correct frequency. If it is a PLL model and the frequency range of the two is the same, the frequency may be wrong. Please change the channel selection to the same correct frequency. point.
2) Microphone failure. If the above two frequency points are the same, either the microphone or the receiver may be faulty. You can test with another microphone of the same model and frequency point. If the receiver can be activated, it means the original microphone is malfunctioning; or Test with another receiver of the same model and frequency point. If it can be activated, it means that the original receiver is malfunctioning.
8. What is the cause of noise in the speakers?
1) The microphone may malfunction and affect the proper current supply.
2) Do not share AC electrical appliances with other electrical appliances in the same socket.
