About JTS RU-8012DB + RU-850LTH

After building on the successful foundation of the US-8002DB, the RU-8012DB UHF PLL Dual-Channel Diversity Receiver incorporates JTS's advanced second-generation wireless technology. Designed to navigate the increasingly congested radio spectrum, this system offers a greater number of compatible channels within a limited bandwidth. The innovative REMOSET feature, a patent-pending technology, allows for easy transmission of scanned channel data with just a push of a button.

Engineered to meet the most demanding audio requirements, the RU-8012DB significantly reduces general and hiss noise to an impressively low level. With an operational range of 100 meters, it caters to a wide variety of applications, from conferences and presentations to vocal performances. To further its commitment to environmental sustainability, an optional integrated charger is available.

The package also includes two RU-850LTB Wireless Bodypack Transmitters. These cutting-edge transmitters are equipped with both REMOSET U and full function settings. Users can easily adjust the frequency, group/channel, sensitivity, RF power, and auto power off settings. All these data can be transferred to the transmitter with a simple push of the REMOSET U button located on the receiver's front panel.

The Auto Power Off feature can be customized to switch off after 10, 30, or 60 minutes of inactivity, thereby extending battery life and preventing over-discharge. In addition to the REMOSET U, users can also make adjustments directly on the transmitter. To accommodate music instruments, a -20 dB pad is included. The transmitter also comes with a built-in recharging circuit and connector for users who wish to upgrade the system.

In summary, the RU-8012DB UHF PLL Dual-Channel Diversity Receiver with 2x RU-850LTB Wireless Bodypack Transmitter and Lavalier Microphone, operating in the 470-960MHz frequency range, offers a comprehensive solution for high-quality wireless audio transmission.
