Overview
The JTS RU-901G3Du is a professional dual-channel UHF wireless receiver designed for installations and live environments where dependable RF performance is essential. Housed in a 1U 19-inch rack chassis, it features genuine True Diversity reception and a wide 36 MHz bandwidth for stable multi-channel operation.
Ideal for theatres, houses of worship, conference venues, touring racks and live performance spaces, it delivers professional reliability in a flexible, cost-effective solution.
True Diversity & RF Stability
True Diversity reception uses dual antennas to continuously compare incoming RF signals and automatically select the strongest source, reducing dropouts and interference in demanding environments.
The 36 MHz switching bandwidth allows multiple wireless systems to operate simultaneously with improved stability. Available frequency ranges:
- 606.5 – 642 MHz (licence required)
- 823 – 865 MHz (licence-free within 863–865 MHz, regional regulations apply)
REMOSET Synchronisation
JTS REMOSET U ultrasonic synchronisation enables one-button transmitter pairing. In addition to frequency, REMOSET can transfer sensitivity, attenuation, RF power, auto shut-down and key lock settings, simplifying multi-channel setup.
Installation & Monitoring
Integral antenna and power cascade functions simplify rack builds where multiple receivers are installed. The backlit LCD displays group, channel, frequency, antenna status (A/B), RF/AF levels and transmitter battery status.
Front-panel controls allow group/channel selection, output level adjustment and frequency scanning.
