We have many customers that want to invest or upgrade their current wireless microphone systems, but are confused by all the different options available to them.
What makes it harder is the rumblings of frequency changes and people discussing channel 70 verses channel 38.
Hopefully we can answer a few of the most common questions you may have regarding wireless microphone and IEM systems below.
If we haven't, just get in touch and we will be happy to help.
What are Channel 70 & Channel 38 - What Does this mean? To keep things very simple, channels 38 and 70 are blocks of frequencies that are available for wireless microphone users to use in the UK.
Channel 70 is a free to use band but it is very small and you can only comfortably run four wireless microphones on this band.
Channel 38 is what's known as the 'shared band' and a licence is needed to run on this channel.
It is a much bigger channel and can fit 10 system comfortably (some even say 12).
The problem is, channel 38 and 70 are so far apart on the frequency spectrum, you can't buy a system with both channels included.
This means you need to decide which band you require before buying the system.
Is Channel 38 right for me? Assuming you have read the info above and you want to use more than four wireless systems, you probably want to know if channel 38 is your only option? Channel 38 is designed for people moving around from venue to venue.
It's a band for touring and gigging musicians and if you are one of those people, we suggest channel 38 is right for you.
If you are only ever using your wireless systems in one venue, you could look at a fixed site licence.
These are blocks of frequencies that you can buy and for your area.
In theory, no-one else is allowed to tune their radio mic systems to these frequencies.
Can I mix and match wireless systems from different manufacturers? If you mean run different systems by different manufacturers side by side, then yes.
Make sure they are tuned to different frequency and correctly spaced and you shouldn't have any problems.
If you mean using one manufactures transmitter with another's receiver, we would say no.
Even if you manage to get them synced together, many of the features won't work and this could cause big problems in the middle of a gig.
Can I use multiple transmitters on one Receiver? I'm afraid not.
You can only use one transmitter with one receiver.
Basically, think of it as one complete wireless system per user.
If you try and run two transmitters on a single receiver they will interfere with each other.
What is Diversity and non-Diversity? Non diversity receivers will just have single antennae that attempts to pick-up the signal from the transmitter.
A diversity system will have two antennae which are competing to receive the strongest signal.
You also get 'true diversity' systems that have two independent RF receiver modules that truly give you the best signal strength.
Hopefully we have answered a few questions you may have had about wireless microphones and you now feel a little bit more confident moving forward.
As stated, we are extremely happy to help you if you have any more questions about your current wireless microphone or a potential purchase.
