UABIAST In-line Power Supply
The Shure UABIAST is an in-line adapter that provides 12V DC Bias power to an active antenna or in-line accessory when a
receiver's antenna input jack does not provide the necessary power. The UABIAST receives power from a wall outlet using a
Shure PS24 power supply, and passes the RF signal while supplying power to an active antenna or other in-line device. It is
capable of supplying power to three in-line amplifiers (Shure UA834), or two in-line amplifiers and one active antenna (Shure
UA874).
Note: For cable runs exceeding 25 feet (7.6 meters), an in-line amplifier (Shure UA834) may be required to compensate for signal loss.
Connecting to a Device
Using Shure 50 Ohm BNC-BNC coaxial cables is recommended when making connections.
Connect the active device that requires DC power into the UABIAST input (marked "RF + DC").
Connect the UABIAST output (marked "RF only") to the antenna input of the wireless receiver.
Plug in a power adapter (Shure PS24) to the DC power input.
The green LED illuminates to verify the 12VDC is active.
