from. These are a little more varied, but there are two basic types. The handheld transmitter and the‘ beltpack’ transmitter. Beltpack transmitters have lots of names. They sometimes get called‘ bodypack’ or‘ pocketpack’ transmitters depending on the manufacturer and application, etc. Here are two examples of handheld and beltpack transmitters.
Plug one of these mics into a compatible wireless transmitter with suitable receiver and away you go!
So these are the three basic elements of a wireless microphone system. Receiver, transmitter and microphone.
In the next part we’ ll look deeper into wireless mic systems, looking at transmission types, frequency ranges, and phase locked loops! And what are the essential facilities and concepts that make some wireless mic systems better than others.
The handheld transmitter is actually a combination of a microphone and a wireless transmitter so it combines the two elements into a single enclosure usually just a little bit bigger than a normal handheld wired microphone, and this item, alongside a receiver forms the basis of a complete wireless system.
The‘ beltpack’ transmitter is a transmitter only and requires a microphone or instrument to be plugged into it. These types of transmitters are used alongside‘ headset’ or‘ headworn’ microphone types, or small lapel mics, sometimes known as tie-clip or lavaliere microphones. Instrument mics such as clipon brass / woodwind microphones or other miniature instrument mics can also be used and electric guitars can also be plugged in via a suitable cable.
One other function that the beltpack transmitter performs is to provide power to the associated microphone. Many smaller microphone types are condenser microphones and require powering. These are very small voltages that can be be provided by batteries within the transmitter, and sent from the beltpack to the mic via the same cable that carries the signal. This is one of the reasons why not all mics can be used with all transmitters. Different beltpacks have different connector types and may also use different wiring arrangements. So it’ s crucial that the mic and transmitter are compatible.
Both types of transmitter will have some form of battery compartments to house the batteries that will power the radio electronics and the microphone( if required).
Microphones for Beltpacks:
The types and range of microphones that can be plugged into beltpack wireless transmitters is pretty vast. There are a whole host of microphones designed for use with wireless beltpacks. Headset, lapel, miniature instrument mics, etc. There are some examples below:
