Well, it seems correct. So you have to do some detective work.Here are a couple of pictures - one is the inputs and the other is the outputs.
The reason this mod works is not because it uses star ground. It works because the flimsy ground connection provided by the ribbon cable is replaced with a much larger gauge wire.
OK, whatever you say.In this particular case, no. X-talk is caused by the topology, that allows mixed signals to be reinjected into the sources. Depending on the actual impedance of said sources, the effect is more or less pronounced. Zero-ohm sources suffer no x-talk, when open circuit is tehemost prone.
Single point ground is what you want. All ground connections lead directly to a single point, which is connected to the earth electrically. Return currents should not travel via these ground paths.A quick question about grounding my summing mixer - what I did was connect all the earths of the sockets together, including the L/R outputs. Is that the best way to do it? Doesn't this mean that there are two separate paths to ground (via the Left and Right outputs)?
