http://www.instructables.com/image/FC6ZZ0XF8JUW8E8/What-is-a-killswitch.jpg This is what I call short circuit. It won't harm a pre-amp doing it by a potentiometer, but I wonder if doing it fast, again and again by a switch won't cause impulses, when the short circuit will be released again? Perhaps I do error in reasoning and it's quite save. _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
