Wireless Microphones

Our range of wireless microphone systems frees a performer or presenter from the cable, with a transmitter on the microphone and a receiver at the desk. We stock complete UHF, VHF and 2.4GHz systems alongside add-on handheld and beltpack transmitters for receivers you already own, in handheld, headset and lapel forms. Found it cheaper elsewhere? We will match the price.

UHF, VHF or 2.4GHz?

UHF is the standard for anything that matters. It offers more usable channels, better range and far fewer dropouts, which is why theatres, churches and hire companies use it. VHF sits lower in the spectrum, costs less and works perfectly well for a single microphone in a small hall, but it is more prone to interference and offers fewer channels. The 2.4GHz systems share the same band as wifi, which makes them licence free anywhere in the world and very quick to pair, at the cost of range and resilience in a crowded venue.

How many channels do you need?

Count the number of people who need to speak or sing at the same time, then add one. A single channel receiver suits a presenter or a lead vocal. A dual channel unit covers a duo or a presenter with a spare microphone, and takes up the same rack space. Multi channel receivers keep four or more transmitters on one shelf and one set of aerials, which is far tidier than stacking separate boxes and much easier to coordinate frequency wise.

Handheld, headset or lapel

A handheld transmitter suits vocals, interviews and anything where passing the microphone around is normal. A headset keeps the capsule a fixed distance from the mouth, which gives consistent level and leaves both hands free, so it suits fitness instructors, presenters and theatre work. A lapel or tie clip transmitter is the least visible option and is favoured for lectures, weddings and video, though it picks up clothing rustle if it is clipped carelessly.

Range, aerials and true diversity

Quoted range assumes clear line of sight, and bodies, walls and metalwork all reduce it. A true diversity receiver uses two aerials and switches to whichever has the stronger signal, which largely removes the dead spots you get with a single aerial. Keep the receiver in sight of the performer rather than behind a wall or inside a metal rack, and lift the aerials above head height where you can.

UK frequency licensing

In the UK, the 863 to 865MHz band is licence exempt and free to use, which covers most of the systems here and is the simplest choice for schools, clubs and small venues. Channel 38, roughly 606 to 614MHz, needs a licence from Ofcom, and shared or fixed site licences are inexpensive and give you cleaner spectrum for larger multi channel setups. Always check which band a system uses before buying, as bands differ between countries and a system bought abroad may not be legal to use here.

Batteries and running all day

Transmitters are the weak point on a long day, so check whether yours takes standard AA cells or a rechargeable pack. Rechargeables pay for themselves quickly on weekly use, but keep a set of alkalines in the case as a backup. Change batteries between sessions rather than waiting for the sound to fail, and switch transmitters off when not in use, since most keep drawing power while muted.

Avoiding dropouts and interference

Set frequencies before an event rather than during it, and where a system offers automatic scanning, use it in the room you will actually work in. Keep transmitters away from LED walls, dimmer racks and wifi access points, and keep at least a few metres between transmitter and receiver, since standing on top of the receiver can overload it. If two systems must share a space, coordinate the frequencies rather than hoping.

Frequently Asked Questions

Is UHF or VHF better?
UHF is better for range, channel count and resistance to interference, which is why theatres, churches and hire firms use it. VHF is cheaper and fine for a single microphone in a small hall, but it has fewer channels and is more prone to interference.

Do I need a licence to use a wireless microphone in the UK?
Not for the 863 to 865MHz band, which is licence exempt and covers most systems here. Channel 38, around 606 to 614MHz, needs an Ofcom licence, which is inexpensive and gives cleaner spectrum for larger multi channel setups. Check the band before buying.

What does true diversity mean?
The receiver uses two aerials and continuously selects whichever has the stronger signal. This largely removes the dead spots you get with a single aerial, so it is worth having wherever the performer moves around.

How many channels do I need?
Count how many people speak or sing at once and add one as a spare. Single channel suits a presenter or lead vocal, dual covers a duo, and multi channel receivers keep four or more transmitters on one shelf with a single set of aerials.

Handheld, headset or lapel?
Handheld suits vocals and interviews where the microphone gets passed around. A headset keeps a constant distance from the mouth for even level and free hands. A lapel is the least visible and suits lectures and video, though it can pick up clothing rustle.

Why does my wireless microphone drop out?
Usually line of sight or interference. Keep the receiver visible to the performer rather than behind a wall or in a metal rack, lift the aerials, and stay a few metres away from the receiver. Move away from LED walls, dimmers and wifi points, and rescan frequencies in the room itself.

What batteries do the transmitters use?
Either standard AA cells or a rechargeable pack, depending on the model. Rechargeables are worth it for weekly use, but keep alkalines in the case as a backup. Switch transmitters off between sessions, as most keep drawing power while muted.
