When not to ground pin 3



I have a Tascam MS-16 with balanced outs wired into a patchbay which
mixes some balanced and unbalanced gear. All of the unbalanced
connections are wired nomally at the bay and have the ring shorted to
the sleeve at the connector end. I was getting a lot of bleed from the
MS-16's outputs into the board and into the inputs some of the effects
in the rack. The only solution was to lift pin 3 on the MS-16 outputs.

Is this the proper way to unbalance the MS-16 (or any other piece of
gear with a transformerless output that carries signal on both pin 2
and 3) or is it an indication that I've got something wrong with my
patchbay wiring?

Ideally I'd like to keep it balanced because I have no polarity reverse
on the board and I can reverse with a patch cable if I need to, but I
can live without that if lifting pin 3 is the only solution.
