In this example:
• For SO-33110/33011, HO-3G, and HO-33110/33011 output
boards, the gain for outputs 17-512 would be boosted by closing
the rear-panel Input Expand DIP switches on both frames and
verifying that the on-board jumpers for that set of outputs are
in the Expand Enable position. The location of the boost jumper
on these output boards is shown on
Figure 105 . The gain for
outputs 1-16 must be held at unity by setting the on-board
jumper for that set of outputs to the Force Normal position; this
overrides the rear-panel DIP switch setting for those outputs.
• For HO-33120/33121 output boards, the gain for outputs 17-512
would be boosted by closing the rear-panel Input Expand DIP
switches on both frames and verifying that the on-board DIP
switches
for those outputs are closed. The location of the DIP
switches for these boards is shown on Figure 106 . The gain for
outputs 1-16 must be held at unity by opening the on-board DIP
switch for that set of outputs; this will override the rear-panel
DIP switch setting for those outputs.
