1.Can I use two microphones of the same frequency at the same time
Cannot be used simultaneously.Wireless transmissions cannot "blend" in the air, and receivers cannot mix two transmissions, even at the same frequency.For example, it is impossible for two FM radio stations to send signals on the same frequency.This can cause confusion and lead to audio distortion.In short, each wireless transmitter should have a separate receiver with its own frequency.
2. What is the difference in frequency of the wireless microphone to avoid interference?
It depends, but at least 4MHz.We can't answer that question explicitly here, because it involves complex calculations.In general, cheaper wireless systems require a wide range of frequencies because of their simple receiver design and limited selection.This limits the number of compatible channels.The system with higher price has better filtering, closer distance between channels and more compatible channels.If we say, "You don't want to do the math yourself," we're right.If you need, please contact the manufacturer or agent, they will help you calculate.Most manufacturers have calculated the compatible frequency of each of Shur's wireless features, so you don't have to do the math yourself.
3. UHF is better than VHF, right?
These two frequency segments for wireless microphones have their own 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.
The following are the advantages of UHF over VHF:
1) UHF frequency band is not "crowded" with VHF frequency band.
2) UHF with flexible frequency can be used in a wider range.
3) UHF features can provide more compatible systems.[For example, the Schur LX and SC (VHF) systems offer only 12 compatible channels, while the Schur UHF system offers more than 100 compatible channels.]
4) UHF system has higher power output, wider frequency shift, better dynamic range and better signal-to-noise ratio than VHF system.
VHF is superior to UHF in several aspects:
1) VHF system is cheaper.
2) VHF has a larger emission range at a specified transmitting power.
3) VHF signal propagation, even through nonmetallic substances.VHF has a long wavelength and is not easily absorbed by the human body.
4. Can UHF system be compatible with VHF system?
Yes, it is compatible with UHF even if the maximum number of compatibilities using VHF systems is achieved.However, the current VHF antenna 'VHF separator' or VHF antenna distribution amplifier of the UHF receiver cannot be connected.
5. The receiver and microphone have been turned on, but there is no signal receiving.
There are two possibilities:
1) If the receiver and microphone are at different frequency points, please change any of them to the same correct frequency point. If it is PLL type and the frequency range of both is the same, it may be the wrong frequency point. Please change the channel selection to the same correct frequency point.
If the above two frequency points are the same, one of the microphone or receiver may fail. Another microphone of the same model and frequency point can be tested. If the receiver can be activated, the original microphone is the fault;Or test with another receiver of the same model and frequency point. If activated, the original receiver is faulty.
6. What is the reason why the microphone cannot be activated?
Check for weak battery power or filling errors.
7. What if the signal transmission distance is short and the signal is off?
1) Please check whether the antenna is installed correctly.
2) Please check whether the battery weak signal indicator light is on.
8. What is the reason for the sound box's buzzing noise?
1) The microphone may malfunction and affect the appropriate current supply.
(2) Do not share the same socket with AC and other electrical appliances.
