Output Level Adjustment
The isolated outputs can be individually adjusted using pre-
set potentiometers, which are accessible through the rear
panel. The gain range of the stereo line isolation unit is -15dB
to +13.5dB (28.5dB).
Internal Jumpers
The unit has jumpers that are used to balance the output
about ground. By default these are not fitted when the unit
leaves the factory.
To get inside the RB-LI2, first ensure that it has been
disconnected from the mains power and that the mains IEC
lead to the unit has been removed. 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.
