Shure UA845UWB Antenna Distribution System

The Shure UA845UWB Antenna Distribution System is a compact, five‑way active antenna and power distribution hub designed to simplify and stabilize RF signal delivery for modern wireless setups. Built to support popular Shure ecosystems such as QLX‑D, ULX, and ULX‑D, this unit consolidates antenna distribution and power management into one reliable rack‑mount solution. Whether you’re running a small corporate event, a touring show, or a broadcast production, the UA845UWB ensures clean, consistent coverage across multiple receivers while reducing the clutter and complexity of separate antenna wiring power supplies. It’s engineered to help engineers minimize dropouts, maximize range, and maintain the highest possible audio fidelity in demanding environments.

• Five independent, active antenna distribution outputs provide robust, evenly amplified RF signals to multiple wireless receivers, helping to minimize signal degradation and dropouts even in complex venue radio spectra.
• Integrated power distribution combines antenna amplification and system power in a single, centralized unit, simplifying installation and reducing the number of individual power adapters required on site.
• Compact, rack‑mountable design supports professional stage and venue installations, delivering high shielding and low RF noise to preserve audio clarity and reduce interference with neighboring gear.
• Intuitive LED indicators for each channel and the power status offer quick at‑a‑glance diagnostics, enabling engineers to monitor signal integrity and respond rapidly to any anomalies during shows or rehearsals.
• Designed to be compatible with Shure wireless systems including QLX‑D, ULX, and ULX‑D, the UA845UWB integrates seamlessly into existing setups, providing a scalable solution for growing wireless ecosystems while preserving system flexibility and reliability.

How to install Shure UA845UWB Antenna Distribution System

• Prepare a well‑ventilated rack space and secure the UA845UWB in a standard 19" rack using the included hardware. Ensure there is adequate clearance for airflow to prevent overheating during long shows or rehearsals.
• Plan your antenna distribution layout by mapping each of the five antenna outputs to the corresponding wireless receivers in your system. Label cables to simplify future maintenance and minimizes on‑site setup time.
• Connect the five RF antenna paths from your antenna farm or distribution network into the five RF input/output points on the UA845UWB. Verify that connectors are firmly seated to prevent micro‑disconnections that can cause signal loss.
• Plug the UA845UWB into a grounded AC outlet using the supplied power cord. Switch the unit on and verify that all channel indicators illuminate and that the power LED is active, confirming the distribution system is powered and ready.
• Link the UA845UWB outputs to your wireless receivers (QLX‑D, ULX, ULX‑D, etc.). Configure receiver frequencies and channel assignments to avoid mutual interference, and use the UA845UWB LED indicators as a quick reference during tuning. For larger shows, document the channel mapping for future reference and maintenance.
