What is the difference between a UR4D and a UR4S?
The UR4S is a single channel receiver, and the UR4D is a dual channel receiver.

How many UHF-R systems can I use together?
You can use up to 47 compatible systems together without audio degradation or interference. Within a given frequency band, you can choose from 3000 selectable frequencies across a 75MHz bandwidth.


Can I easily set up and remotely monitor the UR4D?
Using the Shure Wireless Workbench® System Control Software, which is included with the receiver, you can remotely monitor and control individual and networked receivers.


What does the "+" mean?
In addition to the former UR4D and UR4S, the UR4D+ and the UR4S+ include RF distribution ports that allow up to 10 receivers to share the RF signal from a single pair of antennas.
