Wireless microphone systems are perfect for combining sound quality and ease of use at your events. Whether you need a specific model, it's essential to understand how they work and to know the basic frequencies to consider before making your choice

Everything you need to know about HF Wireless Microphones 

There are three main categories of wireless HF microphones: hand-held, headband and tie microphones. Hand-held microphones are often appreciated for their superior sound quality, while headband and tie microphones are distinguished by their comfort, allowing the user to wear them without strain.

All these models are based on the same transmission principle :

• A transmitter: this can be attached to a belt or integrated directly into the body of the handheld microphone.
• A receiver: a box connected to the public address system.

⚠️  It is advisable not to mix different brands of equipment ⚠️

To ensure optimum compatibility, the transmitter and receiver should come from the same manufacturer and, ideally, from the same product range. A complete kit comprising microphone, transmitter and receiver is often the best option. Not only does this reduce costs, it also ensures perfect consistency between the components.

Some kits, such as the Rondson 5038 2H-83, include several microphones, adapted to different needs. This model, for example, comes with two high-quality hand-held microphones.

When should you choose wireless microphones ?

Wireless microphones are extremely versatile and adaptable to a wide variety of situations. By eliminating cables, they offer total freedom of movement, allowing you to concentrate fully on your performance without having to deal with bulky wires or the risk of getting your feet tangled in them.

They are indispensable in settings such as wedding speeches, seminars or shareholder meetings, where they make it easy to pass the microphone from one person to another, ensuring that your events run as smoothly as possible.

These microphones offer you unrivalled comfort and safety of use, whatever the occasion.

Hand-held microphones are particularly recommended for :

Headband or tie microphones are ideal for performances that require total freedom of movement, leaving your hands free to concentrate on your presentation or performance.

Which frequencies to choose?

The choice of transmission frequency is essential to ensure that your HF microphone system works properly. This type of system operates on a specific radio frequency, enabling fluid communication between the transmitter and receiver.

In France, certain frequencies are reserved for other uses, such as telephony or military activities, depending on national regulations. That's why it's often advisable to choose a multi-frequency microphone, which gives you a wider range of frequencies, reducing the risk of interference.

What frequencies can be used for wireless HF microphones?

The allocation of frequencies in France is governed by ARCEP (Autorité de Régulation des Communications Électroniques et des Postes), which supervises the use of frequencies for equipment such as HF microphones or stage monitors. The frequency bands currently available for HF microphones are :

• VHF band: 174 to 223 MHz
• UHF band: 470 to 694 MHz

In addition, additional frequency ranges can be used in the following interplanes :

• 822 to 832 MHz
• 1785 to 1805 MHz

⚠️ Avoid ⚠️

The following frequencies are reserved for mobile services and must not be used for HF microphones :

• 694 to 790 MHz
• 791 to 821 MHz
• 832 to 862 MHz

At Rondson, our wireless microphones comply strictly with all applicable regulations. It is also important to note that microphone frequencies vary from country to country. If you plan to travel abroad with your equipment, be sure to check the local rules on usable frequencies.

How do I use several microphones at the same time ?

When using several HF microphones at the same time, it is essential that each one operates on a different frequency. If several HF systems are operating on the same frequency, this can cause interference, resulting in degraded sound quality and frequent signal interruptions.

The basic rule to remember is that each wireless microphone should be set to a separate frequency. To make this easier to manage, some microphone sets are specially designed to work with several units simultaneously, ranging from 2 to 4 microphones depending on the model.

So it's crucial to choose an HF microphone system that's tailored to your specific needs to ensure smooth, efficient operation.

Choosing your microphone: Several criteria to consider when making your selection

The criteria to consider when choosing your microphones will vary according to their use. For example, a microphone intended for commercial use will not have the same requirements as one used for a concert or vocal performance.

Once you've taken this into account, concentrate on the five main criteria that will guide your choice :

NOTES TO REMEMBER

There are three types of HF wireless microphone equipment: hand-held, headband and tie microphones, all of which operate with a receiver.

Hand-held microphones are often renowned for their superior sound quality, while headband and tie microphones are appreciated for their comfort and discretion.

These microphones are suitable for a variety of occasions, including receptions, professional events, shows and singing performances. Headworn and tie microphones, on the other hand, allow complete freedom of movement, making them particularly useful in contexts where interaction is essential.

When choosing your microphone, it's crucial to consider a number of factors: sound quality, range, capsule type, signal-to-noise ratio and battery life. For a more secure transmission, we also recommend UHF microphones. Finally, opt for complete sets to ensure perfect compatibility between all the components.
