    Nady U-81 Octavo reviews

    U-81 Octavo HT Wireless Microphone System is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from So far, an incomplete We purchased this system for a church worship group. Having eight wireless mics available for my singers was the overriding factor in using this particular unit. Mics 1-4 work fine, but we have many interference problems with 5-8. The unit is in a closet, 10 feet away from the performance area. We are going to try moving the reciever out of the closet, but are not hopeful that this will cure the problems. The mics seem to be a bit trebly, but nothing that rolling off the high end at the mixer won't cure. On the plus side, having a standby setting on the mics is very handy (the competing product does not).
