    Octavo U-81

    Comments about Nady U-81 OCTAVO Handheld Wireless System (10/11/12/14/15/16/17/18):

    "Come on M"an
    3 of the 8 microphones work flawlessly, Ch. 5 and 7 seem to wash each other out, ch. 8 drops out when you turn your back to the reciever 3 ft. away, Ch.1 distorts under heavy vocals (Only Ch.1). System is used at church, and was purchased through donations from members, and chosen by your trully, I can tell people are very disappointed in my selection, and wish I had just saved up to buy multiple Shure mics. Babied system through the holidays holding my breath the whole time. Nady tech support never returned any of the 4 messages sent.
    Older system was adjustable and much more reliable,
    Purchased older 8 Ch. system, and hoped new technology would be better, wisely purchased 3yr warranty
