JTS Dual Handheld Wireless Microphone System – UF-20R + 2× JSS-20
JTS Dual Handheld Wireless Microphone System – UF-20R + 2× JSS-20
Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
At the pinnacle of JTS's professional wireless range, the UF-20R + 2× JSS-20 system represents a complete dual-channel flagship solution engineered for performers who refuse to compromise on audio quality or RF reliability. This complete package pairs the celebrated UF-20R wideband true diversity receiver with two JSS-20 dynamic handheld transmitters, delivering a ready-to-deploy professional wireless system for the most demanding live applications.
The UF-20R's wideband architecture spans an extraordinary 60–75MHz tuning range, providing up to 3,000 selectable frequencies and genuine flexibility to operate cleanly in virtually any RF environment. REMOSET technology allows the sound operator to remotely adjust frequency, RF power, sensitivity, low cut, key lock, and even user names on each transmitter — all from the receiver front panel without touching the microphones. The built-in cascading power and antenna distribution allows up to 10 UF-20R units to be linked without additional splitters, making system expansion effortless.
The JSS-20 handheld transmitters feature the SAM-8WLN capsule module — designed specifically to minimise handling noise while delivering warm, natural vocal character. The interchangeable capsule system accepts modules from other leading brands, giving you the freedom to use your preferred capsule in the JSS-20 body. Both transmitters are built to the same aluminium alloy standard as the receiver, ensuring the whole system withstands the demands of regular touring and installation use.

Frequently Asked Questions
How many channels can I run simultaneously with the UF-20R system?
The UF-20R is a dual-channel receiver, so this package supports two simultaneous wireless channels. Up to 10 UF-20R units can be cascaded together using the built-in antenna and power distribution, allowing you to scale up to 20 simultaneous channels without additional infrastructure.
What does REMOSET actually do?
REMOSET is JTS's patented RF synchronisation technology. It allows the receiver operator to remotely set the transmitter's frequency, RF output power, sensitivity, low cut filter, key lock, and user name — all from the receiver front panel without physically touching the transmitter. This is particularly valuable during live performances where accessing a performer's microphone is not practical.
Can I use different capsules on the JSS-20 transmitter?
Yes — the JSS-20 features an interchangeable capsule system compatible with capsules from other leading microphone brands. This allows you to use your preferred capsule in the JSS-20 body for a truly personalised sound.
Does this system require a UK wireless licence?
This depends on the operating frequency. The UF-20R's wideband architecture covers a broad UHF range; the frequencies you operate on will determine your licence requirements. For UK use, operation on CH38 (606.5–614MHz) requires a shared PMSE licence, obtainable directly from Ofcom. Operation on CH65 (823–832MHz) and CH70 (863–865MHz) is licence-exempt. Always confirm your specific operating frequency before use.
What is the operating range of this system?
JTS specifies 200–480 metres line-of-sight operating range. In real-world environments with walls, staging, and RF interference, expect somewhat less — but performance remains exceptional for professional live applications.
