You can connect the speakers either with cable lugs or bare wire to the cable termi‐
nals on the rear panel.

15 Ground/Lift switch

In normal operation signal source and power amplifier should share the same
ground potential. In some constellations this admittedly leads to ground loops and
thus to humming. If this happens vary the toggle switch setting for ground poten‐
tial on the rear panel of the unit. This switch connects in one setting the shield/
ground of the input signal with the housing of the power amp and thus with mains
earthing. In the other setting there is no electrical connection between the shield/
ground of the input signal and the power amp housing.
