This Input, however, may
be connected to an unbalanced signal source (Tip-Sleeve) such as a mixer output or
line-level instrument output, and the MS20c balanced outputs connected to a snake
or mixer's balanced input. NOTE: The
Ring of the 1/8" jack MUST be connected to
the Sleeve, and the
bottom XLR Output jack will have it's pin 3 grounded.
The 1/8" jack may also be used as an unbalanced
output
. Connect a balanced signal
to the top XLR Input, the 1/8" jack may be connected via a Tip-Sleeve jack to an
unbalanced input.
By referring to the diagram on the top of the MS20c, you can identify the signal
and grounding paths for all the jacks.
