I understand about the routings and have read the manual front to back many times.
If I connect the eclipse in series with my preamp, with a stereo signal in, then out into a stereo power amp – with the wet/dry mix on 50% I get a good signal in one side and practically nothing in the other. I have used unbalanced 1/4" cables but it appears that there is no signal – or hardly any at all out of the ch1 1/4" out of the Eclipse. This is with stereo in and out with the levels parameters. I have not tried any XLR cables yet.
