[QUOTE="Mike Brown, post: 50717, member: 1310"] Re: Pro 2 AD Conversion - why high pass at 30hz ? That was my first thought as well, but 30 hz is pretty high as a 3dB downpoint for DC offset removal. I could be wrong, but I thought usually the cutoff was much much lower.... like 1 Hz. I am also under the impression that the DL series I/O modules are transformer or electronically balanced (as well as almost ALL outputs you might find yourself plugging into a snake on a professional stage) and won't pass DC current anyway.... can anyone confirm or expand on this belief this for me? My other guess would be trying to reduce LFO style modulation. I am really interested to know the reason! [/QUOTE]
