Radio Microphones FAQ
Q. What is the typical range of Radio systems?
A.
Diversity systems have a greater range than single channel systems. Up to 10 metres for single channel systems and up to 50 metres for diversities.
Q. How do I know if my old radio mics are legal?
A.
If you buy them from DM Music, all our systems conform to MPT 1345, which are license exempt.
Q. Do I need a single or diversity system?
A.
It depends on how near the transmitter is to the receiver and if there is lots of metal in the building. Diversity systems are more stable.
Q. How do I know a good make from a bad one?
A.
DM Music sell more radio mic systems than anyone else in the UK. We know the good from the bad ones and therefore we offer a money back guarantee.
Q. Should I use rechargeable batteries?
A.
Rechargeable batteries need to be discharged completely before recharging. If this discipline is not followed the battery’s life is shortened. Unlike normal alkaline batteries, rechargeables don’t fade, but rather shut down instantaneously. This could be a problem in the middle of a sermon!
How do I get the best from my radio microphone system?
1.
Try to keep your antennas vertical.
2.
Keep the transmitter as close as possible to the microphone, preferably in the ‘line of sight’.
3.
Adjust the squelch control on the receiver to reject signals other than the one it is supposed to receive.
4.
Systems can use rechargable batteries. However they discharge typically only 7.6volts rather than full 9 volts which is not sufficient to operate transmitters properly.
5.
Place lavalier microphone as close to the mouth as possible to avoid feedback.
6.
Do not cover lavalier microphone with items of clothing - wear on the outside of the clothing to avoid feedback and interference.
7.
If the minister in your church insists on walking in front of the speakers you may be advised to purchase a graphic equaliser or feedback eliminator.
What is meant by true diversity systems?
Many cheap radio microphone systems have only one antenna which means they are prone to ‘dropping out’ in mid-performance if a reflected radio signal happens to interfere with the direct radio signal.
Diversity systems however essentially give you two receivers in one box and reduces the risk of ‘drop-outs’ to a minimum.
Even diversity systems which use a second antenna are still prone to problems because they still have one receiver circuit.
True diversity systems essentially give you two receivers in one box, and reduce the risk of ‘drop outs’. DM Music recommends True Diversity systems wherever possible.
