Wireless Microphones
11 April 2011
So we need a Wireless Microphone, you go tot the Mic section and see a problem...
Do I go for VHF or UHF and what is the difference?
VHF = Very High Frequency
UHF = Ultra High Frequency
Each have a Pro and a Con
VHF = Lower Quality - More Range
UHF = Better Quality - Less Range
The VHF channel has a lower quality because it is very crowded, you may have heard stories from friends in the Mobile business where a taxi came through over the PA System, and this is no joke! It is possible as they run on the same frequencies, but generally speaking it is quite rare to get constant interference. UHF on the other hand runs on a less crowded Frequency and therefore has little to no interference. UHF Microphones have a larger range of channels to run on also, so dependent on which model you choose UHF Microphones can work with up to 16 units at once on some the high end Trantec Systems that we can order in specially. The UHF Systems we carry in stock though normally have a minimum of 2 dedicated channels, while other have the option of 4 channels, and moving further up the price scale some system are capable of 256 channel selection, giving you a very wide Frequency range to select from to minimize interference.
And in our opinion that is the main difference between VHF & UHF. VHF is restricted to crowded channels, where as UHF is more flexible.
A Professional DJ who works in hotels for example where there maybe more than 1 wedding going on will need the flexibility of UHF Microphone with a selectable channel, and the room next door to him will have another DJ in who maybe on the same channel, so 1 DJ will need to change Frequencies to avoid coming in over the wrong PA System.
For Bar or Pub work or just Home use, a VHF System would suit the application fine. Many Pubs are unlikely to have another Pub right next door, unless it is a town center, so a VHF Mic would be the practical choice to avoid the unnecessary cost of a UHF model.
