JTS RU-G3TH – UHF Handheld Transmitter with SC-8 Condenser Capsule
Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
The JTS RU-G3TH is the condenser handheld transmitter of choice for vocalists and presenters operating in the RU-G3 series ecosystem — delivering the clarity, sensitivity, and extended frequency response of a quality condenser capsule in a robust UHF wireless transmitter built for professional live use.
The SC-8 electret condenser capsule at the heart of the RU-G3TH captures the natural character of the voice with a level of detail and transparency that dynamic capsules cannot match. Whether used for lead vocals in live music environments, speech reinforcement in corporate settings, or presentation work in conference facilities, the SC-8 consistently delivers clear, natural, intelligible audio. REMOSET U synchronisation allows one-touch frequency and parameter setting from the receiver — no need to access the transmitter during performance or setup.
Available in two UK frequency variants: CH38 (606.5–642MHz) for shared PMSE licence operation; and CH65/CH70 (823–865MHz) which includes the licence-free 863–865MHz band. The RU-G3TH is fully compatible with the JTS RU-901G3, RU-8011DB, and RU-901G3Du receivers — making it an ideal upgrade or expansion component for existing RU-G3 series systems.

Frequently Asked Questions
How does the SC-8 condenser capsule compare to a dynamic capsule for live use?
The SC-8 condenser capsule offers extended frequency response and higher sensitivity than a dynamic capsule, capturing more natural vocal detail and air. The trade-off is that condenser capsules can be more sensitive to high SPL environments and feedback. For vocal performance and speech in controlled environments, the SC-8 is excellent. For very high SPL stages or feedback-prone environments, a dynamic capsule like the JSS-20's SAM-8WLN may be preferable.
Which JTS receivers is the RU-G3TH compatible with?
The RU-G3TH is compatible with all JTS RU-G3 series receivers — including the RU-901G3 single-channel receiver, the RU-8011DB single-channel system, and the RU-901G3Du dual-channel receiver — as long as the transmitter and receiver are on the same frequency band.
Does the CH65/CH70 version require a licence in the UK?
The CH65/CH70 variant covers 823–865MHz. Operation in the 863–865MHz segment is licence-free. Operation across the wider 823–862MHz range requires a shared PMSE licence. The CH38 variant (606.5–642MHz) always requires a shared PMSE licence.
Can I buy the RU-G3TH as a replacement or additional transmitter for my existing system?
Yes — the RU-G3TH is sold as a standalone transmitter and is an ideal addition or replacement for any existing RU-G3 series system. Ensure you select the same frequency variant (CH38 or CH65/CH70) as your receiver.
