8. Ground Lift Switch
This switch allows the circuit and chassis
grounds to be separated in case on a
ground conflict. In normal use the switch
should be in the
Ground On position.
Lifting the ground ( Floating position) may
resolve the ground conflict, but which
means that circuit grounding depends on
other connected components.
Deficiencies in other components’
grounding will affect the sound and a
serious electric fault with the amplifier
could damage other components in the
system.
For the best combination of safety and
performance,it is highly recommended
to keep the switch in the “Ground On”
position,

These are suitable for banana plugs,
spade lugs or bare wires. Spade lugs and
bare wires should both be screwed done

be taken to avoid loose strands of wire
that may cause short circuits.
