JTS RU-901G3DU + 2 x RU-G3TB – Dual Channel True Diversity UHF Bodypack Wireless System
Free Delivery for orders over £150 (order by 3.30pm Mon-Fri).
The JTS RU-901G3DU Twin Bodypack System provides two complete hands-free wireless channels from a single dual-channel receiver — the ideal solution for productions, fitness studios, educational environments, and conferences where two performers or presenters need simultaneous discreet wireless audio.
Two RU-G3 TB bodypack transmitters and CM-501 lavalier microphones are included alongside the RU-901G3Du receiver, giving you a complete, ready-to-deploy dual hands-free system. The third-generation true diversity receiver provides independent full diversity reception on both channels simultaneously, with 1,441 selectable frequencies and REMOSET U one-touch synchronisation for fast, reliable setup without physically handling either transmitter.
The integral antenna and power cascade outputs make system expansion straightforward — additional RU-901G3Du units can be linked without additional distribution equipment, building 4, 6, or 8 channel systems cost-effectively. Available in CH38 (606.5–642MHz, shared PMSE licence) or CH65/CH70 (823–865MHz, includes licence-free 863–865MHz band).

Frequently Asked Questions
Is this system suitable for fitness instruction?
Yes — two bodypack transmitters with lavalier microphones is the standard setup for group fitness classes where two instructors need to be heard simultaneously. The CM-501 omnidirectional lavalier is robust and performs well in active use environments.
Can I mix and match lavalier and headset microphones on the two bodypacks?
Yes — each RU-G3 TB bodypack accepts any compatible 4-pin locking connector microphone. You could run a lavalier on one channel and a headset on the other, for example. Contact us for advice on compatible headset microphone options.
Can I expand beyond two 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 and straightforward.
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.
