hey, I’m busy atm with win isd and I’m not clear about one thing. unfortunately, the manual doesn’t tell you about it either: if I want to include a filter (especially highpass or subsonic) in the calculation you can choose between several variants and certain values change which don’t tell me anything and of which I haven’t read anything in the operating manual of my amp. what does it have to do with it? what do I have to do to calculate with do I see that I want to cut off my hipronics titan 1200d at 35 hz down? thank you for your efforts already in advance=-) nice greeting{{
