K GROUND TERMINALS BLACK = CIRCUIT GROUND
or "Audio Ground"
GREEN = CHASSIS GROUND
or "Electrical Ground" ie mains pin 3
Generally these two ground terminals are connected together with the included "ground strap"
(a small flat piece of metal) but they can be individually used for different grounding systems.
Another use for these is in troubleshhoting HUM problems. Experiment with attaching a wire from
the console to only the BLACK terminal or connecting the GREEN to a rack, (etc).
