MSB Technology The Select DAC - Page 20

Shielding Ground - Basic Operation
The Basic Operation provides isolation only for the DAC. This gets you
half the shielding available. For full shielding, be sure the jumper is in
place between the Chassis Ground and Amplier Ground. This is the
shipping conguration.
NEVER OPERATE WITHOUT THE JUMPER OR A GROUND WIRE
ATTACHED.
Select Powerbase - Advanced Setup
The Select Powerbase has a ground shield network that can oer a
slight increase in sonic performance by connecting all of your MSB
products in a chain and lifting the chassis ground connections.
Shielding Ground - Enhanced Operation
The Enhanced Operation provides isolation for both the DAC
and the amplier. This gets you the full isolation available. In
this conguration 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.
