General Description
The Shure Model UA844+ is an antenna distribution system that allows
for 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 UA844+ system can support up to five wireless receivers. A maxi-
mum of five UA844+ systems may be used in a two-tiered configuration.
