Does this item come with the lavalier and/or headworn microphones, or do you have to buy those separately?
mus4god on Feb 12, 2010
BEST ANSWER: 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.
Do you have these in a different frequency range, per the new FCC regulations, NOT in the 695-802 Mhz range?
Big Mac on Jan 19, 2010
BEST ANSWER: Yes if you desire a specificied range inform us at time of purchase, everthing new shipping out will ship above any 600 range
how many head worn mics do I get with this?

Johnny on Aug 17, 2015
BEST ANSWER: No headset microphones come with the Nady U81 Octavo 8Ch UHF Lavalier Wireless Mic Set. This system comes with 8 lavalier microphones (the kind that clip onto your shirt).
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.
null on Feb 17, 2011
BEST ANSWER: 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.
We own this set in the 900s frequencies and need more wireless mics. What product should we use to not have interference. We've read about not using the 700s frequencies anymore and traded up to the current set, but need more.

BEST ANSWER: Call us at 800-268-5520 for the latest wireless mic product information and optimal usage recommendations.
This comes with the actual headset mics right? I don't see them in the picture.
Fantasia dj on Nov 2, 2010
BEST ANSWER: Supplied with 8 lav mic elements and belt pacs in this configuration.
This doesn't answer my question. What frequencies are these manufactured with now?
MK on Apr 5, 2010
BEST ANSWER: U-81-OCTAVO 8 Channel UHF System - Lavaliers by Nady Systems have selected factory installed frequencies.

*RF Carrier Frequencies - Selected factory installed frequencies between 902-928MHz and 944-952MHz
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?
MK on Apr 1, 2010
BEST 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)

I would buy this product again and again
Pros: All The Above
Cons: none

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.

Well it is just NOT that Flash
Pros: Compact
Cons: Breaks Easily,Poor Sound Quality,Unreliable

I used the set for a school drama production. We practiced with it at close range 20ft from the stage, and although we had a couple of drop outs, it worked relatively well. The disappointing thing was we had 2 lavalier microphones fail on consecutive days, the plug connections to the body pack went all crackly and then stopped working.
Moving back to the operating position at 50ft from the stage for the actual show caused us no end of trouble. Drop outs and two channels virtually stopped working altogether just NO microphone pick up. We limped through with 4 Lavalier Mics working (mostly) and topped up with my OTHER brand lapels for the other 3 channels which we had no trouble with. The drop outs and range of this Nady device is terrible the noise and crackle unbelievable.
