An affordable, single-channel UHF DIgiTRU diversity wireless system for your instrument.

Why worry about tripping over cords or being tied to your amp when you can go wireless with the UHF-3 wireless instrument system. Just plug your guitar or bass into the bodypack transmitter and you've given yourself approximately 250-500 feet of breathing room”enough to explore the stage and get closer to your fans.

The Nady UHF-3 wireless instrument system consists of a half-rack receiver with folding front-panel dual antennas that gives you clear channel UHF operation for optimum interference-free performance, and the aforementioned UB-3 bodypack which is extremely small and convenient.

The wireless receiver gives you a generous 120dB dynamic range thanks to Nady's proprietary companding circuitry. It also offers Tone Squelch for locking out potential interference, DIgiTRU Diversity for maximum range and dropout protection. It provides both 1/4" unbalanced and an XLR balanced output for hooking up to your amp, speakers, mixer, etc.

The UB-3 bodypack has an audio mute switch, bicolor LED status indicator for when the unit is on and to warn you of a low battery, and a locking 3.5mm mini jack so you don't have to worry about your instrument cable popping out during the wildest performances.

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:
