Shure UR4D-J5 2-Channel RF Receiver UHF 578-638 Mhz
This particular wireless microphone device operates in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies.
UR4D+ receivers provide dual-channel option for the premium Shure UHF-R Wireless line. Using the latest in wireless technologies, UHF-R receivers provide advanced control and robust flexibility for a wide range of professional uses.
