The UF-20S/JSS-20 system consists of a Single Handheld microphone and a Top of the range Single Channel True Diversity Reciever

UF-20S Receiver Features:

*Flagship Single Microphone True Diversity system
* Supplied in the UK with a 606-681 MHz Frequency Range.  Channel 38 (606-614Mhz)
* UHF True diversity technology renders 200-480 meters of operation distance.
JTS “True diversity” is when the two independent antennas (antenna diversity) are connected additionally to two independent receiver modules. So not only do they switch to which of the two antennas is getting the best signal, but also which receiver module is getting the best signal. This is JTS’ ultimate method of preventing drop-outs.
* Pre-set 15 groups each of up to 63 compatible channels
* User programmable 6 groups each of 64 channels
* Free space scan function
* JTS Patented obstacle-free RF function synchronizes a transmitter by pushing a button
* JTS LCX circuit design technology minimizes companding noise
* Latest REMOSET not only sends the frequency data but also transmitter’s RF power,
sensitivity, low cut, key lock and 10 Character user's name.
* RF “NO SIGNAL” alert function.
* AF “MUTE” alert function.
* Transmitter “LOW BATTERY” alert function.
