Ground Jumper IN - Basic Operation
The Basic Operation provides isolation only for the DAC. This gets
you half the protection available. Be sure the jumper is in place
between the Chassis Ground and Amplifier Ground. This is the
shipping configuration.
NEVER OPERATE WITHOUT THE JUMPER OR
A GROUND WIRE ATTACHED.
Ground Jumper OUT - Enhanced Operation
The Enhanced Operation provides isolation for both the DAC
and the amplifier. This gets you the full isolation available. In
this configuration you will lift the Grounding lug jumper on both
powerbases and then make a connection between the “Amp Ground”
lug on both the powerbases.
It is important that both grounding lug jumpers are disconnected on
each of your powerbases to ensure proper ground isolation.
With the jumpers disconnected, connect the supplied ground wire
from the AMPLIFIER GROUND lug of ONE powerbase to the chassis of
ONE of your mono-block amplifiers or to your single stereo amplifier.
Note this connection is dependent on the amplifier so you will have
to look for the best place to attach the wire. Generally the easiest
place would be to loosen a screw on the Amplifier Chassis and slip
the open Spade lug under the screw head and tighten the screw. The
only other place a true ground may be found is on the ground pin of
the power connector to the AMP but this will not be easy to connect
to.
