JTS RU-901G3DU Twin Handheld Wireless System – Dual True Diversity UHF
Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
The JTS RU-901G3DU Twin Handheld System puts two channels of professional condenser handheld wireless audio in the hands of two vocalists or presenters simultaneously — from a single compact dual-channel receiver. It's a complete, coordinated package that delivers reliable dual-channel performance for live music venues, theatres, houses of worship, and conference facilities.
Both RU-G3TH condenser handheld transmitters are included alongside the RU-901G3Du receiver, each featuring the SC-8 electret condenser capsule for natural, detailed vocal reproduction. The third-generation true diversity receiver provides independent full diversity reception on both channels simultaneously, with 1,441 selectable frequencies, REMOSET U synchronisation, and integral cascade outputs for easy multi-channel expansion.
Available in CH38 (606.5–642MHz, shared PMSE licence required) or CH65/CH70 (823–865MHz, includes licence-free 863–865MHz band). Both variants deliver the same professional performance — choose based on your licensing preference and operating environment.

Frequently Asked Questions
Is this system suitable for live music with two vocalists?
Yes — two RU-G3TH condenser handheld transmitters provide excellent vocal reproduction for both lead and backing vocals. The SC-8 condenser capsule delivers natural clarity suited to live music environments, and the dual-channel true diversity receiver ensures reliable reception for both performers simultaneously.
How does this compare to the UF-20R twin handheld system?
The RU-901G3DU system operates on a 36MHz bandwidth with 1,441 selectable frequencies — excellent for most live applications. The UF-20R system offers a much wider 60–75MHz bandwidth with up to 3,000 selectable frequencies and REMOSET remote management of more transmitter parameters, making it better suited to large-scale productions with complex RF environments. The RU-901G3DU system offers outstanding performance at a more accessible price point.
Can I expand this to four or more channels?
Yes — the integral cascade outputs allow additional RU-901G3Du units to share antenna and power distribution, making 4, 6, or 8 channel expansion cost-effective.
Does the CH65/CH70 version require a UK licence?
Operation in the 863–865MHz licence-free band requires no licence. The wider 823–862MHz range and CH38 variant always require a shared PMSE licence.
