Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
The JTS UF-20 4 Way Handheld System is a complete, rack-ready four-channel wireless microphone solution for productions and venues requiring four simultaneous handheld vocal channels with flagship-level RF performance. Two UF-20R dual-channel wideband receivers are pre-configured and mounted together, providing four independent true diversity channels with full REMOSET capability.
Four JSS-20 dynamic handheld transmitters featuring the SAM-8WLN capsule complete the package — each offering robust aluminium alloy construction, REMOSET synchronisation, and interchangeable capsule capability. The wideband 60–75MHz architecture provides up to 3,000 selectable frequencies, giving the operator maximum frequency coordination flexibility when running alongside other wireless systems in complex RF environments.
Supplied pre-coordinated and ready to deploy, this system eliminates the time and technical complexity of building a four-channel wireless rig from scratch. The built-in cascade distribution allows further UF-20R units to be added without additional infrastructure, making it a scalable foundation for growing wireless requirements. Requires a shared PMSE licence for UK operation.

Frequently Asked Questions
Is this system suitable for live music with four vocalists?
Yes — this is a professional touring-grade four-channel handheld wireless system. The JSS-20's SAM-8WLN dynamic capsule provides excellent feedback rejection and vocal clarity suited to high-SPL live music environments. REMOSET allows the sound engineer to manage all four channels remotely from the rack.
Can I use different capsules on the JSS-20 transmitters?
Yes — all four JSS-20 transmitters feature an interchangeable capsule system compatible with JTS capsule modules and some classic capsule modules from other leading brands.
Can this system be expanded beyond four channels?
Yes — the UF-20R's built-in cascade outputs allow additional UF-20R units to be added without additional distribution equipment, expanding to 6, 8, or up to 20 channels.
Does this system require a UK wireless licence?
Yes — a shared PMSE licence is required for UK operation. Contact Ofcom or JFMG for details on obtaining the appropriate licence for your operating frequency.
