Shielding Ground - Enhanced Operation
The Enhanced Operation provides isolation for both the DAC and the
amplier. This gets you the full isolation available. With the jumper
disconnected, connect the supplied ground wire from the AMPLIFIER
GROUND lug to the chassis of the amplier. Note this connection
is dependent on the amplier, 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 Amplier 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.
