Wireless microphones are lightweight and easy to use, and many people choose to use them when singing. However, its performance is often affected by various factors such as frequency interference of peripheral equipment and user misoperation, resulting in various failures. What are the common problems in using wireless microphones?
1. Can I use two microphones of the same frequency at the same time?
They cannot be used simultaneously. Wireless transmissions cannot "mix" in the air, even at the same frequency, two transmitted signals cannot be mixed. For example, it is impossible for two FM radio stations to transmit on the same frequency. Because this can create confusion and lead to distorted audio. In conclusion, each wireless transmitter should have its own unique frequency.
2. In order to avoid interference, what is the difference in the frequency of the wireless microphone?
It depends, but at least 4MHz is required. We cannot answer this question explicitly here because it involves complex calculations. In general, cheaper wireless systems require larger frequency gaps because of their simple receiver design and few options. This limits the number of compatible channels. Higher-priced systems have better filtering performance, closer channel-to-channel distances, and a corresponding increase in the number of compatible channels. If we said "you don't want to calculate it yourself", we must be right. If you need it, please contact the manufacturer or agent and they will do the calculation for you. Most manufacturers have calculated the compatible frequency of each wireless function of the ancient Xun, so you do not need to do these tedious mathematical calculations yourself.
3. What is the reason why the microphone cannot be activated?
Check if the battery is low or not filled properly.
4. UHF is better than VHF, right?
Both frequency bands used in wireless microphones have advantages and disadvantages. This is determined by the users of the frequency band, the physical characteristics of the frequency band, and the adjustment limits of the frequency band.
Here are the advantages of UHF over VHF:
The UHF band is not as crowded as the VHF band.
Frequency-flexible UHF can be widely used.
UHF capability can provide more compatible systems [for example, Shure LX and SC (VHF band) systems can only provide 12 compatible channels, while Shure UHF band systems can provide more than 100 compatible channels.
UHF systems have higher power output, wider frequency shift, better dynamic range and better signal-to-noise ratio than VHF systems.
Several aspects of VHF to UHF:
VHF systems are cheaper.
At a given transmission power, VHF has a larger transmission range.
VHF signals even propagate through non-metallic substances. VHF has a long wavelength and is not easily absorbed by the human body.
