Summing Box And 002 Issue

[2JP]

hey all,
hope i'm posting in the right area of the forum for this type of issue.

To get to the point, i am have a strange prob with my summing mixer.
I am running an Apogee rosetta 800 into a passive 16:2 summing box made by Broadcast Pro Audio here in Australia.
From Apogee to Summing box works perfectly, responds as it should.

HOWEVER, when i run outputs from my 002 rack into the Summing box, it behaves strangely.
When i send a single output from 002 into a single channel of the Summing box, and pan the summing channel from mono, to left and to right, it doesn't respond as it should.
When in mono, the signal is quite heavily weighted to the right.
WHen panned hard right, it is pretty much the same as above (mono).
When panned hard left, it cancels the signal entirely.

I have tried alot of things including:
changing all patch leads.
re-checking all patching/signal flow.
cutting up and re-wiring patch leads.
i got another summing box sent out from the manufacturer with same results.
bypassing everything except the 002 and summing box.

I don't know what else to try....i figure it must have something to do with the actual 002 unit??
If anyone has any thoughts or advice please let me know.
cheers

What kind of connections are on the summing box?

Have you tried running the outputs of the Apogee into the channels you currently have the 002 plugged into, and vice versa?

I'm not sure how the 002 could be the source of the problem if you're running individual outs into the summing box...the signal's getting there, obviously, but I don't see how the 002 could make the signal only be panned to the right...

yeah i've tried that...i dunno how it could be the 002 either, it's simply the only thing left in the chain that i haven't tested extensively.
cheers for the thoughts
