[linux-audio-dev] live pa questions

[Marije Baalman]

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.

sincerely,
Marije
