Why wireless?

There are many interesting advantages of wireless microphone systems. One obvious advantage is that no time is required for laying cables. However, one of the greatest advantages is the newly gained freedom of movement, which is practically an essential requirement – and not just for rock concerts. Also for presentations, being able to make gestures gives more weighting to the spoken word and instantly improves the interaction with the audience. Trip hazards due to countless cables are a thing of the past and the stage remains clear. This also creates a more professional impression of the entire event.
And not least, for beginners through to professional users (e.g. for fixed installations), the speed at which the system can be operational is one of the arguments in favour of a wireless system. It is, however, crucial to choose the correct system.

Areas of application

The extensive advantages are not just reserved for large live shows. Being able to move around freely in the space available can also be extremely valuable for smaller performances. Wireless systems are also used in theatre performances and church concerts of all sizes.
Aside from music, wireless systems ensure a professional and clean appearance in the business world. Radio microphones are readily used in conference venues, lecture halls and community centres for applications such as speeches, presentations, meetings and interviews.
The use of a wireless system in conjunction with a headset or a lavalier microphone opens up further possibilities. The singer, or speaker, now has both hands available to interact with his or her audience.  A wireless system is therefore also becoming the tool of choice for sports events, among others.

What do you need to look out for?

Antenna position and range

The positioning of the receiver antenna plays an important role. To guarantee optimal reception, there should be a line of sight between the transmitter and the receiver and the antenna should be as elevated as possible. The range that can be achieved depends on the components used. A minimum distance must also be maintained between the transmitter and the receiver.


The signal strength may be attenuated if there are obstacles in the direct line of sight between the transmitter and the receiver. This phenomenon, know as shadowing, leads to a smaller range. However, the obstacles don’t just include walls or objects. People (the audience) can contribute enormously to the attenuation of the signal. It is therefore particularly important to choose a suitable antenna position to ensure uninterrupted reception.

Permissibility of the wireless system

It must be ensured that the wireless system being used is permitted in the respective country. In Germany, the responsible authority is the Federal Network Agency (BNetzA).  Accordingly, all beyerdynamic radio systems have the required authorization from the Federal Network Agency. A distinction is also made between systems that have to registered and those that do not. 


If various different systems are being used, the frequencies must be carefully selected. If you are operating several transmitters simultaneously at one location, this can lead to disruption of transmission. Reasons for this disruption include interference or intermodulation.
