UHF Wireless Microphones

Your choice of wireless microphone should be based on how you intend to use it. The system you choose will differ depending on whether it is for a presentation, a sales event or a fitness class, etc.

There are three types of wireless HF microphones:

Handheld microphones: Handheld microphones are the most commonly used type because they offer optimal sound quality, ideal for speeches at conferences, presentations or general meetings. 

Microphones headband : these microphones are comfortable to wear, allowing you to move around more easily and freely during fitness classes.

Lavalier microphones: Same principle as for headset microphones, with the added advantage of keeping your hands free, for example during a sales presentation.

Each system operates on the same principle of transmission between:

A transmitter: in the form of handheld microphones, headset microphones, or lapel microphones.

A receiver: this receiver box is usually connected to an amplifier on the existing sound system.

There are microphone systems that combine transmitters, offering versatility and multiple uses.

Before making a final decision on wireless microphone equipment, it is essential to determine the transmission frequency. A HF microphone system operates on a single frequency at a time, which enables transmission between the transmitter and receiver.

Certain frequencies are reserved for other uses, such as telephony or defence-related activities. It is therefore advisable to use a system with multiple frequencies so that you can always select an available range.

The frequencies that must be used for HF microphones are currently as follows, according to ARCEP, which manages the allocation of frequencies to HF microphone equipment:
- VHF band: - 174 to 223 MHz
- UHF band: - 470 to 694 MHz

When using multiple wireless microphones at the same time, it is essential that each microphone has its own frequency, otherwise there is a risk of interference and sound dropouts that could disrupt your communications.

Transmission power is measured in milliwatts, typically ranging from 1 mW to 50 mW. The higher the transmission power of your microphone, the better the range and acoustic performance.

It should be noted that the authorised apparent radiated power (PAR) is 10 mW in VHF and 50 mW in UHF.

Regarding Rondsons wireless microphones, we have power ratings ranging from 10 to 30 mW, namely:

- VHF band 10 mW: WR108DR/VXM286T

- Bande UHF at 10 mW: BE-5018, BE-5038,  BE-1020  et  

- 30 mW UHF band: JS-WM18S and  JS-WM18D

Are you looking for a microphone, preamplifier or speaker model, but want more information before buying, want to compare it with another model and, above all, want to know the best price on the market?

You will find what you are looking for on our specialised blog Studio-Microphone, where we have carried out numerous tests on the leading brands of professional and amateur home studio equipment for you.

Several sections are available, such as :

Dynamic microphones These are the microphones most commonly used in concerts or for radio or television broadcasts. Less expensive than most microphones, they are versatile and easy to use.

Ribbon microphones  A very special microphone designed for direct recording of instruments and loud sounds, to recreate an old analogue sound. Expensive, but almost a collector's item.

USB microphones:  The easiest and cheapest microphones to install, very practical for podcasting, blogging, or even if you are on platforms such as YouTube. They do not require a sound card and are usually plug and play.

A Micro HF which stands for High frequency is either electrostatic to electret such as lavalier microphones or headbands, or dynamic type with moving coil.

HF systems include a transmitter and one or more receivers. They are suitable for commercial activities, teaching, meetings, conference rooms and even singing.
