applications this should cause no problems. For
example, when all outputs feed a single load such
as a recorder or a multiplexer, no grounding
problems should occur. If, however, the amplifiers
feed different loads and these loads have different
grounds, ground loops could occur. Fortunately,
signal levels at the output are usually high, and
small ground currents will not be significant. In some cases, however, noise problems will occur. In
these cases, the user should try to lift the ground tie
point of some of the loads, if possible. Using heavy
drain wires to interconnect loads may be another
remedy. In any event, the output leads, both high
and low, should normally be wired separately from
amplifier to load.
