Comments about Nady U81 Octavo 8 Ch UHF Wireless Lavalier Mic Sys:

This product is cool. I own it and it hasn't let me down at all. Your out of your ******* mind not to own this. Come on, 8 microphones, its the best. If you don't already own this product, buy it before I find you and tell to buy it myself. If you dont want that to happen, then buy the product.

  • Q:

    Is this available in enough frequencies to operate 2 of these (16 mics) simultaneously. I need 16 headset mics by mid March. Two of these would fit the budget I have.

      All of the Nady U-81-OCTAVO System have same Frequencies. You can only use 1 Octavo System at a time. I recommend, one Nady U-81-OCTAVO System and one Vocopro System.

  • Q:

    I saw the answer that all systems will ship above 600 frequency but new FCC says above 806 so will these now be shipped above the new regulations?
    Asked on 4/1/2010 by MK from Kansas

    1 answer



      The FCC has ordered that wireless microphones, in-ear monitors, and related equipment must cease operations in the 700 MHz band (698–806 MHz)

  • Q:

    Does this item come with the lavalier and/or headworn microphones, or do you have to buy those separately?

      There are a few ways to order this. You get to choose between Lavaliers, Headsets, and or Handhelds. You custom order it the way you want and we then order it for you from Nady that way.
