Sennheiser SK 5212-II Bodypack Transmitter

Share

The Sennheiser SK 5212-II is inconspicuous and very comfortable to wear due to its compact design. The transmission power can be adjusted to increase transmission duration and to adapt to regional regulations. The Low Intermodulation Mode (“LoI”) increases interference immunity, especially during multi-channel operation. The switching bandwidth of up to 184 MHz, more than double that of its predecessors, provides extra flexibility. An input sensitivity range of -30 to +40 dB makes the transmitter suitable for use in quiet interview situations as well as with very powerful singing voices in musicals. The SK 5212-II requires only one AA battery for at least 5 1/2 hours of operation and is available in frequency L (470 to 638 MHz) or N (614 to 798 MHz).

CONSUMER ALERT: 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. For more information, visit the FCC's wireless microphone website or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
