The JTS R-4 packs four independent UHF wireless receiver channels into a single 1U 19" rack unit — making it the space-efficient, cost-effective choice for installations, rental companies, and venues requiring four simultaneous wireless channels without filling a rack with individual receivers. It has become the go-to multi-channel receiver for installers and rental operators across the UK.
Cascading antenna and AC power outputs allow multiple R-4 units to be interconnected without additional distribution equipment, making it straightforward to expand from 4 to 8, 12, or more channels. Four independent balanced XLR outputs plus a mixed XLR and 6.3mm jack output provide maximum routing flexibility for both front-of-house and monitoring applications. Available in CH38 (606.5–638MHz, shared PMSE licence required) or CH65/CH70 (823–865MHz, fully licence-exempt).

Frequently Asked Questions
What transmitters are compatible with the R-4?
The R-4 is compatible with JTS RU-G3 series transmitters including the RU-G3TH condenser handheld and RU-G3 TB bodypack. Ensure you select transmitters on the same frequency band as your R-4 receiver variant.
Does the CH65/CH70 version require a UK licence?
No — the CH65/CH70 variant covers 823–865MHz, which is now fully licence-exempt in the UK. CH65 (823–832MHz) became licence-exempt on 29 April 2026 following Ofcom's updated exemption regulations, and CH70 (863–865MHz) has always been licence-free. No licence or registration is required to operate on either band. The CH38 variant (606.5–638MHz) always requires a shared PMSE licence from Ofcom.
