Shure UA844+Z18, UA844+Z17, UA844+Z16, UA844+SWB, UA844+V Quick Start Manual

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 maximum
of five UA844+ systems may be used in a two-tiered configuration.
