tip sleeve

I've got a Soundcraft Ghost console which doesn't have a phase reverse on the tape returns or line inputs. My tape returns are normalled to the board so I decided to wire up some phase reverse points on the bay to use with the insert points. I can't seem to get it to work.

Is it because my insert points are unbalanced?

I have worked on a lot of different systems, by SSL, Neve, Trident and others, and notice that there are MANY opinions on carrying the ground wire in a cable.



I am wondering about advice any here could give me, or even opinions for that matter...



I have both balanced AND unbalanced gear in my patchbays.
