I think the main problem that can occur from DC offset is overheating of
the amp, and then heat protection turns the amp of....
A hi pass filter as said is usually the solution.
You also need to check your dynamic range carefully to avoid blowing
people's ears... (thinks sound very differently on the studio than on
the stage regarding dynamic range.)

Hi,
possibly you can inadvertently add a DC-offset in your signal, which
(depending on the soundcard, I guess) could reach your PA unfiltered.
This then can put your speakers in a constant offset-state, limiting
your dynamic range and possibly hurting it.
A simple highpass filter, set to a rather low frequency will rid you of
any DC-offset.

Hi all,
Is there a chance that signals generated from software could damage live PA
equipment? I'm guessing not, as there is obviously (I assume) some limiting
built into soundcards, but I'm just wondering what applications do to, if
anything, to help.
It's just something that worries me sometimes when playing live, and
generating particually nasty noises by accident, or design :)
cheers,
