Hi
They have 5 connections:
Sleeve (ground)
Tip
Tip switch
Ring
Ring switch
They are inherently 'balanced' wireable but the way yours has been done
is unbalanced.
The switch contacts are used for 'normalling' so for an insert return
for example your tip and ring switch contacts come FROM the preceding
output stage (usually with a jacj wired as a 'listen' and the tip and
ting contacts would go into the next stage or piece of gear.
Examine a jack carefully and you will see that the tip and ting tags are
slightly thicker than the switch contact tags.
As you say R is also grounded in your setup, which is to be expected
since it is unbalanced. You need to unlink this so that it can become
the 'cold' phase of your balanced cabling.

PS I haven't really examined your picture and assume you have 5 tags.
The other possibility is that you only have 3 tags (no switch contacts).
In this case you can't do 'normalling' but only 'listens' or in / outs.

Bros....
the patchbay on my series IIIc is confusing me.
i am readying the desk for a master insert module to be installed, and was
going to hi-jack (no pun intended) 4 points on the bay for the sends and
returns. i know the bays are wired unbalanced ... but i wanted to rewire them
balanced. with a tt inserted into the point on the lower left (as seen in the
picture attached) i test for continuity from T, R, and S to identify the
corresponding solder points. the S is the common ground rail seen in the
picture... good... i expect that... T is the 3rd tab up from the ground
rail.... ok... R is also the ground rail. Hmm. Are these points all internally
unbalanced? are they configurable to balanced at all? if not, why in the world
are they manufactured with 4 tabs on the bottom?!?!
thanks...
