JTS UF-20R/JSS-20 Description

The JTS UF-20R/JSS-20 combines a rackmount dual-channel UF-20R true diversity receiver with two JSS-20 handheld transmitters. The receiver uses PLL synthesized frequency control and offers a wide selection of operating frequencies for configuring multi-system wireless installations.

The UF-20R receiver is housed in a 1U metal chassis and features an LCD interface that displays group, channel, frequency, antenna A/B status, RF and AF levels, mute status, transmitter battery condition, REMOSET ID, user name, and squelch information. Balanced XLR and unbalanced 6.3 mm outputs provide connection options for mixers, powered speakers, and other professional audio equipment.

JTS REMOSET technology provides wireless synchronization between the receiver and compatible transmitters. In addition to frequency information, the system can communicate settings including RF power, sensitivity, low-cut status, key lock, and user name, reducing the amount of manual configuration required at the transmitter.

Each included JSS-20 handheld transmitter features PLL synthesized tuning, selectable low/high RF power, a low-cut function, slot-in charging capability for two AA NiMH rechargeable batteries, and an interchangeable capsule system. The JSS-20 is supplied with JTS's SAM-8WLN capsule, designed for strong acoustic performance while reducing handling noise.

With true diversity reception, wideband tuning, extensive preset and programmable channel options, and system monitoring functions, the UF-20R/JSS-20 is well suited to professional live sound, presentations, performance stages, houses of worship, and installations that require two handheld wireless microphone channels.
