100 Volt Audio, Band I or Band II?

Dutch of the Elm

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.

    and that is why the mains cables will be  insulated and sheathed, or armoured according toi the environment, - assuming you will allow the mains to be bare and insisting the speaker cable needs to be bomb proof is the wrong approach.
