Correct, and btw. the ground cable in the main sockets are always a little bit longer. However, for e.g. the Brauner VM-1 tube microphone it's similar done as described here: http://sound.westhost.com/earth-f4.gif The microphone is sold to all western nations, used by many experienced engineers. IIRC we only used a capacitor, however, we bought a capacitor that is intended for this usage. The switch to chose between a direct connection and the connection by capacitor was labeled "ground lift". You might call it hard-grounded and soft-grounded, all terms are equivocal. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
