Re:SA 750 question...help*note!

Please note that I only have experience with system III and GainMaker...Older models may have been designed differently.

SA says that the interstage pads/eqs are factory set to ensure operational gain of the station and should not be changed unless specified by system design. They are debating placing them beneath inner module cover so few would bother changing them. They are typically 0-1.5 pad and 7.5 eq. (5 pad...9 eq for underground) and 0-2 pad with a 10.5 eq. on amps.
The other three pads you mentioned are rev. input pads. Little variance (in value) of these pads is important so ask a supervisor or someone involved in testing to give you a set value to use system wide. They figure this value by subtracting the level received at the headend from the level you are injecting (lets say 39...19 for design amp + 20 for loss) at an amp (or avg. of many test locale). This value represents the value of rev. inputs needed...
Hope that helps somewhat...
