INSTALLATION

1.Thread the Shure Model UA830 unit on the supplied stand (Figure 2), or on a 5/8 in.-27 thread microphone stand.

2.Connect the antenna to the TO ANTENNA port on the Model UA830 unit (Figure 2).

3.Using 50 W low-loss coaxial cable (purchased separately, Shure UA825 or UA850 or UA8100 recommended), connect the TO RECEIVER port of the UA830 to the Shure Model UR4 or ULX wireless receiver or UA845, or UA844 Antenna Distribution System (see Figure 3 for UR4 Receiver example).

4.If a second UA830 Line Amplifier is needed for extremely long cable runs (over 15 m [50 ft]), (Shure model UR4 and UA845 only) repeat steps 1 to 3. See Adjusting for Different Cable Lengths.

UA830 specifications

The Shure UA830 is a high-performance antenna distribution system that plays a critical role in the world of professional wireless audio. Designed for use with Shure’s ULX, ULX-D, and QLX-D wireless systems, the UA830 is engineered to enhance performance by allowing multiple receivers to share antenna signals while minimizing potential interference.

One of the standout features of the UA830 is its capability to distribute antenna signals to up to four wireless receivers. This not only simplifies setup but also ensures optimal performance across all connected devices. With the ability to effectively extend transmission range, the UA830 is ideal for larger venues and complex setups commonly found in concert halls, theaters, and broadcast environments.

The UA830 employs advanced technologies, including low-noise amplification, which ensures that the integrity of the audio signal is maintained even when distributing it across multiple devices. This technology minimizes signal loss and amplifies weak signals, delivering a clearer, more reliable audio experience.

Another impressive characteristic of the UA830 is its versatility. It supports a wide frequency range and is compatible with various Shure wireless systems, making it a crucial component for audio professionals. Its rugged design is built to withstand the rigors of touring and live events, ensuring that it remains reliable in demanding situations.

In terms of connectivity, the UA830 features multiple RF outputs, with each output designed to maintain a 50-ohm impedance, which is key in preventing reflections and ensuring efficient signal transmission. The unit also includes a front panel that facilitates easy monitoring and control, allowing technicians to quickly assess signal strength and performance levels.

Furthermore, the UA830 is equipped with an integrated power supply, which simplifies the installation process and reduces clutter associated with external power sources. It also features a series of LED indicators to provide real-time feedback on device status and signal integrity, allowing for quick troubleshooting when needed.

In summary, the Shure UA830 is an essential tool for professional audio engineers and technicians, offering stellar performance, advanced technologies, and rugged reliability. Its ability to distribute antenna signals effectively across multiple receivers makes it a top choice for enhancing wireless audio systems in a range of environments.
