Professional wireless systems demand reliable power solutions, and the Shure UABIAST in-line adaptor rises to meet this challenge by providing essential 12V DC bias power to active antennas and accessories when your receiver’s antenna input lacks the necessary juice.
This clever adaptor draws its power from a standard wall outlet via the included Shure PS24 power supply, seamlessly passing RF signals whilst simultaneously supplying power to your active antenna or other in-line devices. The UABIAST maintains signal integrity throughout the power delivery process, ensuring your wireless system operates at peak performance.
The unit’s versatile power distribution capabilities allow it to supply three in-line amplifiers such as the Shure UA834, or alternatively support two in-line amplifiers alongside one active antenna like the UA874. This flexibility makes it an invaluable tool for complex wireless installations where multiple powered components require reliable bias power distribution.
