JTS SPT-1T Description

The JTS SPT-1T wireless transmitter is engineered for dependable performance in demanding environments. Utilizing a phase-locked loop (PLL) frequency system within the UHF 470–506 MHz band, it ensures stable frequency operation with minimal deviation (<±10kHz) and reduced interference. Its selectable 10mW or 50mW RF power output (depending on regional regulations) provides flexibility in range and power consumption, making it suitable for both compact and large-scale setups. With advanced modulation capabilities and low spurious emissions, the unit maintains high signal integrity and fidelity. An onboard LCD display offers real-time monitoring of key transmission parameters including frequency, channel, mute status, and power level. Dedicated controls allow for easy adjustment of frequency, group, transmitted power, and key lock functions for secure operation. The SPT-1T excels in wireless system installations where cable-free operation, low-latency, and professional-grade transmission are required. It pairs seamlessly with compatible JTS receivers to create a fully integrated and reliable wireless audio chain.
