Active Antenna/Power Distribution System, five-way, wideband VHF and UHF, internal power supply. Five-Way Active Antenna Splitter and Power Distribution System for U4S, UR4S, U4D, and UR4D receivers, AD4, ULXD4, UXLD4D, ULXD4Q receivers, SLX4, BLXR4 and QLXD4 receivers.
The Shure Model UA845UWB is an amplified, VHF and UHF Antenna Distribution System that expands a wireless microphone system by splitting one pair of antennas to multiple Shure Axient Digital, UHF-R, ULX-D, BLX4R, SLX4 and BLX4R. It also amplifies RF signals to compensate for insertion loss due to splitting signal power to multiple output connectors. Each UA845UWB allows up to four receivers to use the same antennas. CASCADE connectors allow connections to a fifth receiver or a second UA845UWB.
Expandability. The UA845UWB Antenna Distribution System is designed for large Axient Digital, UHF-R, ULX-D™, QLX-D, SLX, BLX4R wireless systems. Each unit allows up to four wireless receivers to use the same two antennas, and the CASCADE ports allow connection to a fifth receiver or a second UA845UWB.
Compatibility. The UA845UWB is compatible with all Shure Axient Digital, UHF-R, ULX-D, SLX, BLX4R, QLX-D wireless microphone receivers operating within a compatible frequency range (see UHF Carrier Frequency Ranges in the Specifications section).
CASCADE Ports. Two 50 Ω, BNC-type antenna CASCADE ports allow an additional UA845UWB unit or a fifth wireless receiver. A large wireless system can be run off of a single pair of antennas.
Power OUTPUT and OUT Connectors for Shure UHF and UHF-R® Wireless systems. Up to five U4 or UR4 receivers can be daisy-chained and powered from a single source via the Power OUTPUT connectors. DOES NOT APPLY TO ULX or ULX-D.
System Features
The Shure Model UA845UWB ensures maximum sensitivity and signal processing capability, providing the widest radio range possible for the largest number of wireless receivers.
-
5 Selectable Frequency Ranges The UA845UWB allows more options for avoiding intermodulation artifacts by switching between one of the five frequency bands.
-
RF Power LED Indicators Front panel LED indicators display red if RF power is overloading.
-
Expandability The UA845UWB Antenna Distribution System is designed for large wireless systems. Each unit allows up to four wireless receivers to use the same two antennas, and the cascade ports allow connection to a fifth receiver or a second UA845UWB.
-
Compatibility The UA845UWB is compatible with all Shure wireless microphone receivers operating within a compatible frequency range.
-
Cascade Ports Two 50 ohm, BNC-antenna cascade ports allow an additional UA845UWB unit or a fifth wireless receiver. A large wireless system can be run off of a single pair of antennas.
-
Power Output and Out Connectors Multiple receivers can be daisy-chained and powered from a single source via the power output connectors.
-
Low Noise and Intermodulation Distortion The UA845UWB maintains clean signals with minimal distortion.
-
Insertion Loss Compensation Whenever a signal is split to multiple output ports, there is a loss in signal strength. The UA845UWB amplifies signals to compensate, ensuring a strong signal to the receivers.
-
Front-Mounted Antennas The UA845UWB comes with hardware to front-mount the antennas, if desired.
