Radio Mics: A Complete Buyer's Guide
Choosing a wireless mic system means more than picking a brand. Here is what matters in practice — frequency, format, digital vs analogue, and what to prioritise at each budget.
Buying radio mics is more involved than buying cabled microphones. You need to consider frequency licensing, the number of simultaneous channels you need, battery life, the intended application, and whether digital or analogue suits your situation better. Get these decisions right before looking at brands or prices, and the buying process becomes significantly more straightforward.
Step 1: Understand Your Frequency Options in the UK
In the UK, radio mics must operate within Ofcom-approved frequency bands. The most accessible option is Channel 38 (606–614 MHz), which is licence-free. Any professional-grade system in this band can be used anywhere in the UK without registration. For multi-channel setups beyond what Channel 38 can support, a shared spectrum licence from Ofcom covers specific UHF bands at a modest annual cost. Never buy a system built for the 800 MHz band — that spectrum was repurposed for mobile broadband in 2012.
Step 2: Decide Between Handheld and Bodypack
Handheld radio mics are for vocalists and presenters who want a mic in hand. Bodypack transmitters suit actors, fitness instructors, speakers and anyone who needs hands-free operation with a lavalier or headset. Many entry and mid-level radio mics systems include the bodypack transmitter as standard; some packages include both handheld and bodypack transmitters for one receiver. If you need both formats, check whether the receiver is compatible with both transmitter types.
Step 3: Choose Between Analogue and Digital
Analogue systems are simpler, cheaper at the entry level and have effectively zero latency. They are adequate for most live vocal and spoken word applications. Digital systems offer better audio quality, higher channel density in a given frequency range, and — on broadcast-grade equipment — encryption. For studio recording, broadcast or situations where audio quality is critical, digital is preferable. For general live use, a good analogue system from a reputable brand is a practical choice.
Spec Priorities by Application
For live music and theatre, prioritise reliability and range. Look for diversity receivers (two antennas), a wide tuning range so you can adjust around interference, and adequate battery life for the longest performance or run. For video and broadcast work, audio quality and latency matter more — look for digital systems with low-latency modes and good frequency response. For conference and presentation use, ease of setup and battery reliability are often the most important factors.
Budget Tiers
Entry-level radio mics from brands like Rode (Wireless GO series), Sennheiser (XS Wireless) and Shure (BLX) are well-regarded for general use. These typically work in Channel 38 or close equivalents and offer solid performance for solo or small multi-channel setups. Mid-level systems from the same brands — Sennheiser EW-D, Shure QLX-D — add digital audio, wider tuning and more channel management. Professional systems from Shure (ULX-D, Axient Digital) and Sennheiser (Digital 6000) are specified for broadcast and large live production use.
