that running a PA with no speakers is in no way harmful. It is similar
to having an electric outlet without anything plugged into it, your
Most amps won't mind being unloaded, notable exceptions being
those having a transformer at the output (e.g. tube amps).
real danger is too heavy a current drain (ie. sticking
a fork in the
electric socket, or a low impedance speaker in a speaker jack that
cannot handle that low and impedance).
A well designed amp should survive that as well - certainly
if it's meant for PA where cables and plugs get damaged and
a short circuit is a real possibility.
Some amps are designed to survive almost everything except
a direct lightning strike. I once drove a power drill using
an Amcron DC300A, it worked perfectly and I'm still using
that amp...
