What is the difference between UHF and VHF microphones?

Author:admin   AddTime:2021-06-04

VHF has little reflection on small metal objects and can be diffracted; it can penetrate non-metal objects such as the human body; the loss of the feeder is low, and the antenna can be appropriately extended; the battery can be used for a long time; it is affected by VHF TV channels, paging, and letter machines And industrial pollution, such as electric welding, motor, etc., have large interference; the usable frequency range is 61MHz, the expandable range is too narrow, the frequency is crowded when using the multi-microphone, and the compatible frequency is less; the dynamic range of the signal is small.

UHF reflects a lot of small metal objects, and multi-path propagation can cause interference; it shields and attenuates non-metal objects such as the human body; the loss of the feeder is large, and the receiver should be as close as possible to the microphone; it requires a larger transmission power and battery life Short; less high-frequency interference; usable frequency range of 270MHz, large expandable range, can be used by multiple microphones, can form a larger system; the dynamic range of the signal is large.



Conclusion: Generally, VHF is suitable for hotels, convention and exhibition centers, and teaching systems. UHF is used for radio and television, theater performances, and systems where multiple sets of channels work at the same time, using antenna diversity reception.

According to experience, both systems should be tested before the performance during the performance. The main purpose is to check whether the electromagnetic space at the scene is suitable for using your microphone. VHF does interfere with each other when using the multi-microphone. Of course, it cannot be said. UHF doesn't have it, but it has a large extension range and can be adjusted as much as possible. I used to do projects in a hotel near the telecommunications bureau. Neither VHF nor UHF can be used. Because there are multiple transmitting stations on the telecommunications building, there are serious interferences, so it is better to use wired microphones.
