ADJUSTING FOR DIFFERENT CABLE LENGTHS

FIGURE 4

The longer the coaxial cable connecting the UA830 unit and the receiver or distribution amplifier, the greater the possibility for signal loss. The UA830 comes with a GAIN switch that can compensate for signal loss in longer cables. Shure recommends using the Shure UA825 or UA850 or UA8100 coaxial cable when remote mounting antennas. NOTE: Use only 50Ω low-loss cables (RG-8 or equivalent).

Set the switch according to these guidelines:

•UA825 Extension Cable (7.6 m [25 ft])-Set GAIN switch in 3 dB position.

•UA850 Extension Cable (15.2 m [50 ft])-Set GAIN switch in 10 dB position.

•UA8100 Extension Cable (30.4 m [100 ft])-Set GAIN switch in 10 dB position.

•If over 15.2 m (50 ft) is required, a maximum of two UA830's (Shure model UR4 and UA845 only) may be chained together. See Figure 5. The Gain switches for each UA830 must be adjusted separately. No more than two may be chained.

*To maintain Shure UA825 and UA850 or UA8100 cables in top condition in permanent installations:

•Avoid sharp bends or kinks in the cables.

•Do not deform cables with makeshift clamps, such as bending a nail over the cable.

•Do not use cables in permanent outdoor installations

•Do not expose cables to extreme moisture

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.
