For almost every application there is a specific wireless system configuration available. Which one is the best choice for you, depends on how you want to use it.

Your usage application is only one key factor in choosing a wireless microphone. Also consider the microphone transducer design and polar pattern. These greatly impact how any wireless microphone reproduces your live sound. For example, if you are a vocalist who performs onstage with loud monitors, you might want a handheld transmitter with a cardioid or even supercardioid polar pattern to minimize feedback.

If you tend to sing in a low voice a condenser microphone helps to produce a clearer and more natural sound. If you have already used a wired Shure mic (e.g. the SM58R) it makes sense to choose the same microphone capsule with a wireless system.

For presentations or in a theater, lavalier and headworn microphones with an omnidirectional polar pattern are suitable, as floor wedges are rarely used for these applications. These microphones are the least sensible to breathing noise and deliver the most natural sound – which is particularly beneficial for speech applications.

Every wireless microphone system has a certain maximum amount of compatible channels that can be used simultaneously. If you are operating only a single system in one location, you can choose any wireless system available. Before choosing a wireless system you should consider how many systems might be added in the future in your band. This also includes wireless in-ear-monitoring systems.

If you choose a system with maximum four compatible channels it can become tight pretty fast. Better systems allow for eight, twelve or even more units to be operated at the same time without interference. Therefore you should consider the maximum amount of compatible channels with a wireless system before the purchase.

If you operate more than one wireless system the carrier frequencies have to be chosen carefully, as RF signals interact and interferences can occur. If you are using wireless systems of the same type this is normally no problem as the frequencies are usually stored in groups that are compatible with each other.

With different wireless systems this is more complicated. Units with Auto Frequency Selection help to find an open frequency automatically and avoid sources of interference. Should you have difficulties in finding open frequencies please contact the Shure Support Team.
