An affordable wireless system that lets you deliver your message!

The DKW-3 LT Omni Lavalier Wireless System includes the DKW-3 Receiver and the WLT Bodypack Transmitter, and the LM-140 omnidirectional lavalier/lapel microphone. It offers exceptional audio that is virtually indistinguishable from that of a cord. VHF (170-216 MHz) operation provides reliable, interference-free performance. The DKW-3 has a typical operating range of 150+ ft.-up to 300+ ft. line-of-sight.

This system is easy to use-simply plug into your audio mixer or amplifier in place of your wired microphone. Advanced audio processing circuitry gives you a wide dynamic range with no overloading for loud inputs or background hiss during quiet use. Controls include a Front panel Power On/Off switch with a Power On LED for easy operation. The back panel has a ¼" audio output jack and DC power input jack for AC/DC adaptor. Special circuitry eliminates transmitter on/off "pop" noise.

Consumer Alert:

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 FCCs wireless microphone website at:

    Comments about Nady DKW-3 LT/O Lav Wireless System:

    I have owned this unit now for 2 years and still enjoy the quality of sound and freedom it has given me especially with my video productions. I have also recommended purchasing this unit to people who are taking video production courses in college to help them with their continuing projects. Nady has been around for years in the music scene and I still have complete trust in this name brand!
