Grounding and Shields
A full discussion of proper studio wiring schemes is beyond the scope of this
manual, but, in general, the shield should be connected to pin 1 of the output con-
nector. The shield should be connected to ground at only one end; however,
although not recommended, the shields can often be connected at both ends with-
out a problem.
