JTS UF-20S – True Diversity Wideband Wireless Receiver (CH38)

JTS UF-20S – True Diversity Wideband Wireless Receiver

Overview

The JTS UF-20S is a professional single-channel true diversity wireless receiver designed for demanding live sound and installation environments. As part of the flagship UF-20 series, it delivers exceptional RF stability, extended operating distance and wideband frequency flexibility.

Operating across a massive 60–75MHz bandwidth within the 606–681MHz frequency range, the UF-20S provides thousands of selectable frequencies and advanced system management features, making it ideal for complex multi-channel wireless setups in theatres, venues and touring applications.

True Diversity Reception

True diversity technology utilises dual receiver circuits and antennas to constantly monitor signal strength and automatically switch to the strongest signal. This dramatically reduces dropouts and ensures reliable wireless performance even in RF-challenging environments.

• True diversity receiving mode
• Wideband 60–75MHz operation
• Carrier frequency range: 606–681MHz
• Operating distance up to 200–480m (environment dependent)

Advanced REMOSET Synchronisation

JTS’ patented obstacle-free RF REMOSET technology allows transmitters to be configured remotely from the receiver. With the push of a button, the receiver can synchronise transmitter parameters including frequency, RF power, sensitivity, low-cut settings, key lock and user name.

Extensive Frequency Management

The UF-20S offers a huge selection of frequencies for flexible system configuration:

• 15 preset groups with up to 63 compatible channels each
• 6 user-programmable groups with 64 channels each
• Up to 3000 selectable frequencies
• Free space scan function

This makes the UF-20S ideal for multi-channel wireless systems in large-scale productions.
