Specifications; Licensing Information - Shure UA844SWB Manual

General
The Shure Model UA844SWB is a UHF antenna distribution system that allows
the expansion of wireless microphone systems by splitting one pair of antennas to
multiple receivers. It also amplifies RF signals to compensate for insertion loss that
results from splitting signal power to multiple outputs. A single UA844SWB system
can support up to four wireless receivers. A maximum of five UA844SWB systems
may be used in a two-tiered configuration.
Model Variations
UA844SWB:
Includes all components
UA844SWB/LC:
Includes all components, excluding antenna cables and locking
power cables
Note:
A power switch on the front panel is included on some units, depending on country-specific
regulations.
