100 Volt Audio, Band I or Band II?

Hi.

With reference to 100 Volt audio lines of a public address system, would the interconnecting cabling be considered Band I or Band II?  

While the audio signal is not 50 HZ, I would call it AC, and hence the voltage might suggest Band II. 

For obvious reasons I would not want to run audio with mains voltage wiring, so the audio may have to go in its own containment as it cannot go in the Band I containment either. 

It will be wired in 300/500V rated cabling in any case.  

What are people's thoughts on this? 

Thanks.

  • Isn't 100V line audio, generally run 'earth free'?

    The 100V line stuff I'm used to working with was derived by using an output transformer, the secondary side of which was not referenced to earth.
