Amplifier is off; otherwise the
speakers’ components could be
damaged.

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,

9. Binding Post Output Ch1/ Ch2

These are suitable for banana plugs,
spade lugs or bare wires. Spade lugs and
bare wires should both be screwed done
tightly to exclude oxygen, and care should
be taken to avoid loose strands of wire
that may cause short circuits.
