The clearest, most natural sound available in wireless today.

The Nady U-800 Guitar Wireless System includes the Nady U-800 Receiver and the UB-800 Bodypack Transmitter with the GT cable.

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:
