Most microphones use active elements, and thus generate electricity.
It is possible if one is aware of it, to set up a PA system that
"only" violates derabbanans. But that isn't the default, IMHO.

: Microphones that are on before Shabbos and not touched are no
: different wrt Melacha than hearing aids which operate on the same
: principle (amplifying the sound passively). I don't know of any Poskim
: that prohibit using a hearing aid on Shabbos.

But one can be meiqil on a derabbanan for kavod haberios that one couldn't
for stam a microphone.

Tir'u baTov!
