An affordable wireless system that operates two lavalier microphones simultaneously.

The DKW-Duo LT Omni Lavalier Wireless Microphone System includes the DKW-Duo Receiver, two WLT Bodypack Transmitters, and two LM-140 omnidirectional lavalier/lapel microphones. 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-Duo 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:
