This Shure UHF‑R 2‑Channel Wireless System in the H4 band configured with two UR1‑H4 bodypack transmitters, two UR2‑H4 handheld transmitters, a UR4D‑H4 dual receiver, two Shure active paddle antennas, and two mic stands provides a durable, tour‑grade wireless package built for professional live sound, corporate AV, and large‑venue events. The UHF‑R platform offers a wide 60 MHz tuning bandwidth and supports up to 40 compatible channels per band, giving it strong flexibility for crowded RF environments while using Shure’s Audio Reference Companding to deliver clearer analog wireless audio with reduced compander artifacts. The UR4D‑H4 receiver includes automatic frequency selection, infrared sync for pairing transmitters quickly, true diversity reception for dependable RF performance, and Ethernet networking for integration with Shure Wireless Workbench software, which enables coordinated scanning, frequency planning, and multi‑receiver monitoring across large systems. The UR1 bodypacks and UR2 handheld transmitters operate cleanly within the H4 band’s UHF range and integrate seamlessly with the receiver for stable transmission. To further improve RF stability, the included Shure active paddle antennas provide directional gain and stronger rejection of interference compared with standard whips, helping extend usable range and minimize dropouts in reflective or high‑traffic RF spaces. With the addition of two mic stands for the handheld units, this H4‑band UHF‑R setup forms a complete, reliable dual‑channel system designed for consistent wireless performance in demanding professional environments.
