    The clearest, most natural sound available in wireless today.

    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.

    Features 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.
