Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
The Q Audio QWM1970BP-4W is a complete four-channel hands-free wireless system designed for venues, schools, theatres, and corporate events where four simultaneous headworn or lapel microphone users need professional wireless coverage. Everything required is included in a single package — receivers, transmitters, microphones, and antenna distribution unit.
Operating on the CH38 licensed band (606.5–613.5MHz), this system delivers the reliable, interference-resistant UHF performance that four-channel hands-free wireless operation demands. A UK Wireless Microphone Licence (PMSE shared licence) is required to operate this system — available from Ofcom at modest annual cost, covering UK-wide use on a shared basis. A genuinely complete turnkey four-channel hands-free wireless solution.

Frequently Asked Questions
Does this system require a licence to operate in the UK?
Yes — the QWM1970BP-4W operates on the CH38 band (606.5–613.5MHz), which requires a UK Wireless Microphone Licence (PMSE shared licence) from Ofcom. This covers UK-wide use, is straightforward to obtain online, and is renewed annually at modest cost. A licence must be in place before the system is used at any performance or event.
What is the antenna distribution unit and why does it matter?
The ADU (antenna distribution unit) allows all four receiver modules to share a single pair of antennas rather than each needing their own. This simplifies installation significantly — particularly in permanent venue installs — and ensures consistent antenna positioning for all channels simultaneously.
