The UR4S+ receivers are part of the flagship UHF-R system and provide single-channel options for premium wireless. As "+"-versions these receivers include RF distribution ports that allow up to 10 receivers to share the RF signal from a single pair of antennas. Up to 47 compatible systems may be used together without audio degradation or interference. Within a given frequency you can choose from 3000 selectable frequencies across a 75MHz bandwidth. Using the Shure Wireless Workbench® System Control Software, which is included with the receiver, you can remotely monitor and control individual and networked receivers.
