JTS JSS-20 – Dynamic Handheld Transmitter with REMOSET
Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
The JTS JSS-20 is the definitive professional handheld transmitter for the UF-20 system — a super wideband UHF transmitter that combines REMOSET remote management, an interchangeable capsule system, and slot-in rechargeable battery capability in a single aluminium alloy body built to touring standards.
At the heart of the JSS-20 is the SAM-8WLN capsule module — JTS's latest development in dynamic capsule technology, engineered specifically to deliver outstanding acoustic performance while minimising handling noise. For engineers and performers who prefer a different capsule character, the interchangeable capsule system accepts modules from other leading microphone brands, allowing a truly personalised sonic signature in the JSS-20 body. A sliding cover design protects the setting controls from accidental changes during performance.
REMOSET compatibility allows the receiver operator to remotely adjust the JSS-20's frequency, RF output power, sensitivity, low cut setting, key lock, and user name from the receiver front panel — without physically accessing the transmitter. This is invaluable during theatrical productions, broadcast, and large-scale live events. The JSS-20 is also compatible with JTS CH-2 and CH-8 wireless charging stations for venues requiring rechargeable operation.
