Q-Audio Quad Headworn/Lapel Wireless Microphone System with Antenna Distribution
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.
The integrated antenna distribution unit (ADU) feeds all receiver modules from a single pair of antennas, dramatically simplifying installation and reducing cable runs compared to running multiple independent receivers. Each of the four channels delivers true diversity UHF reception with independent frequency selection and ACT infrared pairing for straightforward coordination. All four beltpack transmitters are supplied with both headworn and lapel microphone options, providing flexibility for different presenter and performer preferences.
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.
Is this system suitable for a school production or theatre?
Yes — four channels of hands-free wireless is ideal for school productions, drama performances, and theatrical events where multiple cast members need to be mic'd simultaneously. CH38 provides reliable spectrum for all four channels, and the included headworn and lapel options give the sound operator flexibility to choose the most appropriate microphone placement for each performer.
Can I mix headworn and lapel microphones across the four channels?
Yes — each beltpack is supplied with both a headworn and a lapel microphone, so you can use different microphone types on different channels simultaneously based on your requirements.
