1. Locate LK2 near the bottom of the board, as shown in
Figure 2-1.
2. Remove the shorting jumper if you want to float the
input/output grounds from case ground.
3. Leave jumper LK2 in place if you want to connect
input/output ground to case ground.
Normal amplifier operation is recommended
with circuit ground connected to case ground
(float disabled). This minimizes susceptibility
to system noise. Enable the floating-ground
configuration only for applications requiring a
floating ground.
