routed so that they are not likely to be
walked on or pinched by items placed
upon or against them.

AC ground wire connected to the
electrical system ground. Precautions
should be taken so that the means of
grounding of a piece of equipment is not

fier channel back into another
channel’s input.

nect an amplifier output with any
other amplifier output.
