Actually, it's not really all that hard to break out L and R to
different connectors - although it does tend to be a bit wasteful of one
of the two pairs...
Start with BOTH pairs going into one connector. Strip the appropriate
amount of the outer jacket, and separate the pairs. Cut one pair (I
usually trim the red/black pair, designated LEFT or CH. 1) back to a
normal working length, but DO NOT TRIM the drain. Install connector in
normal fashion, folding the drain wire at the length you'd have trimmed
it to before soldering. Before assembling to the shell, slip the
removed outer jacket over the second (Green/White) pair, and the free
end of the drain wire, and run the resulting cable back through the
shell connectors, bushings, strain reliefs, etc. Install the second
connector to the free end in normal fashion. You now have a cable end
that might LOOK a bit strange, but gives excellent performance. I have
also done it with trimmed drain wire; it will give good results, as
well, depending on the equipment connected and the length of the
pigtailed second pair - even in the near-field of a 5 kw AM station.
(Oh, and use a permanent marker to designate which connector is what
channel.... so the next guy will have a clue, as well as in case you
forget between install and maintenance time.)
