Each signal’s gain adjustment pot is directly behind the signal’s
connector on the daughter board and is labeled TR#.
The extender board fits both input and output board sets; however, input
and output board sets fit together conversely so you must flip the
extender board to fit each set. To adjust gain on an output board, attach
the extender board’s male connector to the switching board; for an input
board set, attach the female connector to the switching board (see graphic
below).
Immediately after adjusting signal gain, remove the extender board. Do
not continue normal operation of the 8Y-XL with the extender board in
place.
