The Nady U-800 Lavalier Wireless System includes the Nady U-800 Receiver and the UB-800 Lavalier LT Bodypack Transmitter.

The U-800 has the best performance and price value in professional UHF wireless, offering clear-channel, frequency-agile operation on the UHF band for interference-free performance in any application or locale. The U-800 delivers 800 user-selectable, frequency synthesized channels in the US frequency band 470MHz- 490MHz. The Nady U-800 offers built-in Autoscan for quick and convenient open channel selection and set up of one system, or many wireless systems at the same location for simultaneous multichannel operation. The U-800 features proprietary companding and low-noise circuitry for an industry-best 120dB dynamic range, and the clearest, most natural sound available in wireless today.

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:


U-800 Reciever
Unsurpassed state-of-the-art PLL UHF performance with 120dB dynamic range and long range operation, up to 500 ft. (line-of-sight)
800 user-selectable UHF frequencies, with one-touch Autoscan open-channel automatic selection
ASC (Auto-Sync Channels) download feature sends selected channel information to transmitter via IR sender for easy frequency synchronization
Sophisticated IF filtering for optimal simultaneous operation of up to 14 systems in the same location
To facilitate multiple, simultaneous systems operation setup, the 800 selectable channels are available from 10 optimized factory pre-set groups of up to 14 compatible channels and 5 additional user-select groups, all offering 800 channels each. All groups retain in memory the previously selected channels for that group for easy setup subsequently in the same location.
