Ground-link Internal Jumpers
The unit has jumpers that are used to balance either the input, or the output, about ground.
By default these are not tted when the unit leaves the factory.
To get inside the RB-PLI6, observing anti-static precautions, undo the four crosshead screws
on the back panel at the far left and far right of the panel (2 at each end). Also undo the
small brass screws, which hold the top and bottom panels to the rear panel. The rear panel
should slide backwards out of the unit together with the main circuit board.
