JTS RU8012DB/RU850LTH Description

The JTS RU8012DB/RU850LTH combines high-end wireless performance with user-friendly control, making it ideal for professional audio setups. The RU8012DB receiver supports two channels simultaneously with antenna diversity reception, reducing dropouts and ensuring reliable signal capture even in challenging environments. It offers a wide 36MHz bandwidth and an ultra-low distortion rate of less than 0.6% at 1kHz. The unit also includes REMOSET remote sync technology, allowing users to set transmitter frequencies directly from the receiver via ultrasonic signal — streamlining setup time. The dual handheld RU850LTH transmitters feature selectable RF power levels, auto power-off, and adjustable gain control. Each mic includes an LCD+LED display for real-time feedback on group, channel, frequency, and battery status. Designed for rugged live use, the transmitters are powered by two AA batteries and include onboard mute and key lock functions. Together, the system delivers clean audio with a signal-to-noise ratio over 105dB(A), minimal spurious emissions, and intelligent squelch with pilot tone and noise muting. With two independent balanced XLR outputs and two ¼" unbalanced outputs, the RU8012DB offers complete connectivity for mixers, speakers, and PA systems.
