GROUND
NOTE: If AC hum problems are encountered, disconnect the cable shields from pin–1 (cut the
jumper in unbalanced systems). Shield grounding will then be provided from the other end only,
and the path for a probable "ground loop" is broken.
CAUTION
Do not use "AC ground lifters" to solve hum problems.
A serious shock hazard may result.
