Re: Advice on new set upThis seems extremely unlikely, Jorge. If you were to connect your iPhone directly to a passive speaker you might hurt the iPhone, but not the speaker, and it wouldn't get very loud. Powered speakers are designed to be able to accept a wide range of line level (and mic level for some) signals, which the iPhone can capably provide. The common complaint with using iPhone/iPod/iPads for playback is that the music on them is often lossily compressed e.g. in MP3 format. However, in my experience most nowadays is compressed well enough that you won't be able to hear it through a PA, and the compression is of the kind of character that if you can't tell its errors apart from errors in your PA then you shouldn't be working in audio.
