Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at http://www.fcc.gov/cgb/wirelessmicrophones.
Ideal wireless system for presenters of any kind.
The applications for this system are as vast as the field of communications. Here's a partial list: business presenters, auctioneers, comedians, bingo callers, dance instructors, ministers, square dance callers, tour bus narrators, lecturers, hog-callers and so on. The Nady DKW-8U system provides superb value in wireless vocal amplification for speech. This package contains Nady's unidirectional microphone, which means it has a focused pickup pattern. In louder environments, this is probably the one to select, as it does a better job of rejecting feedback than an omnidirectional microphone.
This system consists of a lavalier microphone that attaches to a tie, lapel or the speaker's button front, which then attaches to a belt-pack transmitter, and a receiver that typically resides near the input of whatever amplification system is being used. From the speaker's mouth to the input jack of the amplification device, the DKW-8U provides a clear, robust wireless audio signal that is appropriate to professional applications.
Even with obstacles such as walls, displays and crowds, response is reliable to 150 feet.
