Wireless Microphones

Choose VHF for a simple one- or two-microphone setup and UHF when more channels must run together. QTX notes that its VHF systems, such as the 171.816UK, can run a maximum of 2 VHF frequencies in combination, while UHF systems such as the Citronic TU4 171.043UK run four programmable channels with an auto frequency sweep.

No, not for systems listed as licence-free. The Chord 171.983UK and 171.984UK beltpack systems list licence-free operation in the UK and EU, the Citronic TU4 171.044UK lists licence-free operation, and QTX VHF systems such as the 171.817UK and 171.818UK are listed as licence-free in the UK. Check the listing of any other system before use.

Listed ranges are 50m for QTX systems such as the 171.800UK and 171.817UK; 60m for Chord and Citronic UHF systems such as the Chord 171.984UK and Citronic TU4 171.043UK. Walls, people and other radio equipment shorten the working range, so keep the receiver in sight of the stage and mount antennas on the front of a rack.

Yes. The QTX U-MIC 171.800UK receiver plugs into a USB port or USB power supply and outputs a mix of its two handhelds to a 3.5mm jack, and the 171.806UK set works the same way with one handheld. The QTX 171.824UK J-MIC set has a rechargeable plug-in receiver with an 18650 Li-ion battery and two metal-bodied handhelds.

A beltpack system with a neckband or lavalier microphone, so nothing has to be held. The Chord 171.983UK beltpack system is supplied with a choice of neckband or lavalier microphone, the QTX 171.818UK has two beltpack transmitters with neckband headsets, and the Citronic TU4 171.044UK has four bodypacks supplied with neckband and lavalier microphones.

Yes, with a transmitter that matches the system and frequency of your receiver. Replacements include Chord NU4 handhelds such as the 171.954UK at 863.10MHz, Citronic TU4 transmitters such as the 171.046UK, QTX VHF bodypacks such as the 171.941UK at 174.1MHz, and Adastra handhelds for SA-series wall amplifiers such as the 953.153UK at 864.5MHz.

As many as there are receiver channels on separate frequencies. A dual receiver such as the QTX 171.816UK takes two handhelds on 173.8MHz and 174.8MHz, and the Citronic TU4 171.043UK runs four handhelds with individual XLR outputs. For a larger show, add systems on different frequencies and plan them together so they do not clash.

Yes. The Chord 171.983UK and 171.984UK receivers are half rack-width and fit standard 19in racks with the included rack ears and front antenna accessories, and the Chord 171.895UK BNC antenna extension lead lets an antenna be mounted on the front of a rack. The QTX 171.810UK has a half-width 1U receiver.

It is an extra clip-on transmitter with a built-in microphone for the Citronic LM58 5.8GHz wireless lavalier system, so two people can be heard through one receiver in interviews and presentations. Its rechargeable Li-ion battery is listed at 5 hours of operation, and its listed maximum range is 60m.
