his chart is meant as an aid in tracking control, status and metering signals between the PA Controllers and th
ndividual PAs. The first column groups the PAs by Z-Plane. The second column gives the actual PA
esignation or location as silk-screened on the inside of the PA doors. As for columns 3 through 6, each PA
ontroller is identical and has the ability to control 8 PAs, PA1-PA8. However, an output labeled PA1 on the
A Controller schematic does not necessarily go to amplifier A1 or B1. For example, On Z-Plane A, amplifier
4 is connected to any input or output of PAC #2 that is labeled PA7, such as PA7_GATE. Note that on Z-
lane B, amplifier B4 is connected to any input or output labeled PA8 on PAC #1. This cross numbering is due
o the fact that Z-Plane B is inverted compared to Z-Plane A. The seventh column is actually the intermediate
tep between the PAs and the PA Controllers and gives the designation and connector number for each of the
As. The last 2 columns give the component designator for the Isolation Switch and Isolation Resistor for each
f the PAs. The Isolation switches and resistors are located on the Isolation boards mounted on the sides of the
-Planes.
