Overview

This Nady U-81 OCTAVO Wireless System is a professional 8-channel UHF wireless system which offers clear, natural-sounding wireless, providing you with 8 UB-81 bodypack transmitters with lavalier microphones. The Nady U-81 OCTAVO delivers eight discrete channels on selected frequency bands 902-928MHz and 944-952MHz for interference-free performance in any application or locale. The wireless mic system also features Nady's proprietary companding and low noise circuit for an industry best 120dB dynamic range.

UH-81 Handheld Transmitter
The Nady DM-50D neodymium cartridge in each UH-81 handheld transmitter helps them deliver transparent vocals, maximum feedback rejection, and minimal handling noise. They also have an On/Standby/Off switch for convenient audio muting, a status/low battery LED indicator, and are made of rugged ABS and rubber-coated housing with integral antennas.

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.
