Excellent gain before feedback and suppression of background noise. It operates on phantom power only and is terminated for Shure wireless systems using a TA4F-type connector.
Wireless microphone devices operating in portions of the 617-652 MHz or 633-698 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 the that date if their operations could cause harmful interference to a 600 MHz service licensee's wireless operations on these frequencies. For more information, visit the FCC's wireless microphone website at or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
