Hi there i jusat got a soundcraft 760 24 track, and when i get it all
hooked up to my patch bays, it only passes a low leval of sound. but
when i pull the patch cable out a little i get full power sound. what
could this be.
everything is ballanced, and i have 3 wierd snakes that are some
soundcraft elco to female and male xlr that i have hooked to my patch
bay with a bunch of hosa xlr to 1/4" trs snakes.
I'm lost and lossing it. thanks Ryan

Sounds like a grounding issue.

Pick up the tracer or a pair of headphones and start tracing signal
from one point to another. Is this a long frame patchbay? Are the
snake cables wired properly. Are the outputs _really_ balanced?

Sounds like part of the balanced wiring / connectors may be "2 hot" and some
"3 hot". This would certainly cause the problem.

No, not at all. Pin-2-hot and Pin-3-hot balanced lines will interconnect
nicely, just with a phase inversion which is usually fine.

The problem comes when you have unbalanced lines driving only one pin,
and unbalanced receivers connected only to the other. But in this case,
things are NOT "perfectly balanced."

Miswiring somewhere. Check it out carefully. Maybe it's not really
balanced, and tip and ring are reversed. When you pull the plug out
a little, the tip of the plug is connecting to the ring of the jack
and apparently that's what's making it work.

Good luck with the Soundcraft 760. The company was never know for
making tape decks.

THEN, neither your inputs nor your outputs are actually balanced.
This is an important thing to know when it comes time to integrate other
gear.
