For the Big Gigs, Go with Shure Wireless!

This Shure UR4D+ dual-channel receiver adds even more flexibility to an already great unit. You get rear-panel RF distribution ports, which allow up to 10 receivers to share an RF signal from a single antenna pair. This URD4+ receiver operates on the L3 Band (638-698MHz).

The Shure UHF-R wireless system gives you the tools you need to handle large-scale, no-mistakes-allowed live situations. A Shure UHF-R system provides 2,400 selectable frequencies across a 60 MHz bandwidth, with up to 40 compatible systems per band. Shure's Advance Track Tuning shifts the RF filter along with the selected frequency, maximizing signal isolation from interference. The UHF-R system also features networked automatic setup to minimize time and effort, plus infrared transmitter sync. Integrated Wireless Workbench software with Ethernet and USB compatibility gives you advanced, real-time control and monitoring of large systems. Shure's famous Audio Reference Companding technology ensures exceptional audio quality.

Shure UHF-R Wireless Systems master the high pressure and extreme conditions of any large-scale touring or installation environment while delivering unparalleled Shure sound. The UR4D receiver features rock-solid engineering, the latest technology and the most robust RF performance to arm you with all the features and flexibility you need to tightly control up to 108 systems for the most elaborate productions.

Shure's exclusive Track Tuning filter enables UHF-R systems to employ increased bandwidth without increased interference. The filter moves with frequency selection, maximizing isolation of signal from interference, and maximizing compatibility. With Track Tuning, the UHR-F systems make previous bandwidth limitations for high-fidelity wireless irrelevant!

The UHF-R systems deliver premium-quality audio utilizing Audio Reference Companding. This technology applies a variable companding ratio rather than a fixed ratio to eliminate "breathing" and other wireless artifacts. Audio Reference Companding also increases dynamic range to provide a signal that's clear and clean.
