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 frequencyThis is how many times a sound or radio wave oscillates in one second.Read moreGo to the glossary band, you can choose from 2400 selectable frequencies across a 60 MHz 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.
