Cable-free systems
Wireless microphones for rent, with no dropouts or interference
Handheld, bodypack, headset and lavalier. The microphone itself isn't what matters most: it's frequency coordination, antenna placement and batteries.

How it works
A wireless mic is a miniature radio station
And like any radio station, it needs a free frequency, a well-placed antenna and a battery. The three classic failures at events all come down to these.
A wireless system has two parts: a transmitter (the handheld mic itself or a bodypack worn on the belt) and a receiver connected to the mixing desk. A radio signal travels between them on a specific band. If that frequency is taken by other equipment, a radio station or another microphone at the same event, you get crackles, dropouts or simply silence.
The four formats
- Handheld. The most versatile and the easiest to pass between several people. For presenters, speeches, interviews and singing.
- Bodypack with headset. The bodypack goes on the belt and the headset over the ear, with the capsule at a fixed distance from the mouth. It's the most stable option for level and allows the most gain before feedback: ideal for officiants, speakers who move around, instructors and entertainers.
- Bodypack with lavalier. More discreet on camera, but the level varies when the person turns their head and it suffers from clothing noise. Good for video and static formal events.
- Bodypack for instruments. A clip-on mic for wind instruments, accordion or percussion, and an instrument cable for electric guitar or bass when the musician moves around.
Frequencies
How many wireless mics can run at once without interfering
There is no magic number: it depends on the equipment's frequency band, the bandwidth available and how crowded the spectrum is at that point in the city. There is, however, a practical rule: the more systems you run together, the more coordination work is needed, and simply spacing them out "a little" is not enough. Two badly chosen frequencies create intermodulation products that sound like interference, even when each channel is clean on its own.
In practice, when an event calls for several systems, this is what we do:
- Scan the spectrum on site, not at the warehouse. The radio landscape is different in central Seville, at the fairground and at a country estate in the Aljarafe.
- Coordinate the whole group, calculating the frequency plan so that no combination interferes with another.
- Antennas with line of sight to the stage, plus an antenna distribution system when there are many receivers.
- A spare channel, already coordinated, in case interference appears in the middle of the event.
Real-world range
Brochures talk about a hundred metres; at an event, with an audience, metal structures, LED screens and walls in the way, the usable figure is quite a bit lower. What really matters is line of sight: a receiver behind a load-bearing wall or inside a closed rack has less range than one mounted high up and in view of the stage. When the speaker moves between rooms or the event moves from place to place, we plan an additional receiver or change the approach.
Batteries: the silliest and most common failure
Every wireless unit leaves the warehouse with fresh batteries and a spare set at the desk. On long days, such as all-day conferences or full weddings, they are swapped halfway through during a break, even if the indicator still shows charge. A microphone that dies mid-speech costs far more than all the batteries in the world.
Choosing the format
Handheld, bodypack, headset or lavalier
| Situation | Format | Why |
|---|---|---|
| Presenter or master of ceremonies | Handheld | Easy to pass around and replace |
| Civil or religious ceremony | Bodypack with headset | Hands-free with a consistent level |
| Conference speaker being filmed | Bodypack with lavalier | Discreet on camera |
| Panel discussion with several speakers | One per person, coordinated | Requires frequency coordination |
| Sports activity or entertainment | Bodypack with rugged headset | Withstands sweat and movement |
| Band with a singer who moves around | Handheld + instrument bodypack | Coordinated spare recommended |
What we do
What's included
On-site scanning and coordination
Before the sound check, not once guests have arrived. That is what means there are no surprises.
Fresh batteries and spares
Every system goes out with fresh batteries and a spare set available at the desk throughout the event.
Properly placed antennas
High up, in line of sight with the stage and away from LED screens and motors, which are sources of noise.
Testing with the actual speaker
We set the gain with the person who will be speaking, not with our own voice. Everyone projects differently.
Placement explained
We show where the headset goes, how to clip on the bodypack and which button not to press by mistake.
Spare channel
At important events we keep an extra system switched on, coordinated and with its level set, ready to go.

What it pairs with
A wireless mic on its own makes no sound: it needs a mixing desk and speakers. And at public events, it often needs PA coverage too.
Frequently asked questions
Wireless microphone FAQs
How many wireless microphones can I use at the same time?
With two or three there is rarely a problem anywhere. From four upwards the frequencies need to be coordinated properly, and from eight upwards an antenna distribution system is advisable. Tell us how many you will need and we will have them set up before they leave the warehouse.
Can the battery run out in the middle of the event?
They go out with fresh batteries and we bring spares. On long days we change them during a break, even if the indicator still shows charge. It is the easiest fault to avoid, so we never leave it to chance.
What range does it have?
Enough for any normal event if the receiver is properly placed. What reduces range is not distance itself but what is in the way: walls, metal structures, the audience and screens.
Why do I hear clicks or dropouts?
Almost always because of frequency interference, a badly placed receiver or a low battery. All three are prevented beforehand: by scanning the spectrum, placing the antenna in line of sight and changing the batteries.
Does the headset show up much in photos?
There are slim, skin-coloured headsets that go largely unnoticed in photos. If looks come first above all else, the alternative is a lavalier, accepting that the level is less stable.
Can I use a wireless mic with my own equipment?
Yes. We supply the receiver with its output ready to connect to your mixing desk or powered speaker, with whatever adaptor is needed.
