GROUND LINK

In some installations, it might be necessary to isolate the crossover electric ground, from
the system mains earth, in order to avoid ground loops, that could generate unwanted
noises, for this reason, the crossover provides an EARTH-LINK switch placed at the rear panel
in order to lift the mains earth from the crossover electric ground.
