That's it I could pay a set with a head SKM5000 me 5005 (supercardiode singing) and Receivers em 3031.

Advantages: Design, Door (50mW power of mission), transmission of the state batteries Receivers, high quality sound (I think CHARACTERISTICS seen, the 5005 has me rponse one more than me homogne 5005th), modularity ease of use ...

Inconvnients: Receivers imposing 16 frquences fixed (not easily changed), price (of course)

Overall I think it is THE REFERENCE
