Shure UR4D+ Dual Channel Diversity Receiver
Shure UHF-R® Wireless Systems master the intense pressure and extreme conditions of any touring or installation environment, while delivering unmatched Shure sound. Offering you more productivity, more reliability and more control, UHF-R is premier wireless technology that helps you master the complexities of large-scale wireless installations. UHF-R takes wireless to a completely new level.
Unparalleled control for complex installations. UHF-R automates setup and control operations to save you time and effort on even the most complex networked installations. UHF-R’s usability innovations include networked Automatic Frequency Selection with group scan, infrared automatic transmitter sync and smart menu-driven system operation for fast setup and intuitive operation.
Superior RF performance and reliability for every installation. With 2400 selectable frequencies across 60 MHz of bandwidth, UHF-R provides up to 40 simultaneous compatible systems per band. Advanced Track Tuning Filtering Technology, by shifting the RF filter along with the selected frequency, allows you to deploy this added bandwidth without audio degradation or interference. All UHF-R components – including the compact, sweat-resistant bodypack – are engineered to withstand the abuses of the road. You can rely on UHF-R for consistently reliable performance, always.
Crystal-clear audio that sounds more like wired. Shure’s patented Audio Reference Companding delivers crystal-clear audio transmission, far superior to conventional wireless. Unlike other wireless systems, Shure uses a variable compounding ratio that responds to the audio level – eliminating wireless artifacts and substantially increasing dynamic range.
