The Shure UA845 is an amplified UHF/wideband antenna and power distribution system designed to expand wireless microphone setups. It allows multiple receivers to share a single pair of antennas, minimizing rack clutter and simplifying antenna management in large installations. Key Features

• Five-Way Active Splitter: The unit splits one pair of antenna inputs into up to four outputs for wireless receivers, plus an additional pair of CASCADE ports for connecting a fifth receiver or a second UA845 unit, allowing system expansion.
• RF Signal Amplification: It features a built-in amplifier that compensates for the insertion loss caused by splitting the antenna signal, ensuring consistent and strong signal strength to all connected receivers.
• Power Distribution: The UA845 includes DC power outputs to power the connected receivers directly, which eliminates the need for individual power adapters and further reduces rack clutter.
• Frequency Range: 782-806MHz.
• Compatibility: It is compatible with a range of Shure wireless microphone systems, including the U4, UR4, ULX, ULX-D, QLX-D, SLX, and BLX (BLX4R only) receivers (compatibility may vary by specific UA845 model/frequency range).
• Internal Power Supply: The unit has an internal switching power supply and can also daisy-chain AC power to a second unit.
• Durable Design: Housed in a standard 1U rack-mountable metal chassis, it is built for professional live sound and studio environments.
