I doubt the DC offset would get as far as the PA or stereo.
Something in the signal path is going to be AC coupled for safety
reasons so that would get knocked out. (None the less be careful!) :-)
As for the low frequency issue why not put a high pass filter, in
Jack Rack or in the program itself if it supports normal LADSPA
plugins, to get rid of that issue?
Hope this helps,
