A wireless system that lets you look, act and sound natural!
The Nady U-81 Octavo HM3 is a wireless microphone system that includes the U-81 Octavo Wireless Receiver, HM-3 Wireless Headworn Microphone, and the UB-81 Bodypack Transmitter.
The U-81 Octavo wireless system offers clear channel operation on the wide-open, uncluttered UHF band for interference-free performance in any application or locale. The Nady U-81 delivers 8 discrete channels on selected frequency bands from 740MHz to 764MHz. The Octavo HM3 system features Nady's proprietary companding and low noise circuit 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: www.fcc.gov/cgb/wirelessmicrophones.
