Processor/EQ: 2 Channel Low-Level Input / 6 Channel Low-Level Output
The same layout applies to 6 and 4-channel processor Product Groups (a 2-channel processor group may use
a 922 for input signal and a 920X for output). The Low-Level Bus connections should be routed to the corre-
sponding bus connections on the next module in the Product Group or the Model 980 System Module (front
output bus to position "A" on the 980A, rear bus to position "B" & Sub bus to position "C"). See Model 980
Setup Diagram for the next installation step.
If your system includes head units with both low-level and high-level signal output, special wiring is re-
quired for setting up the proper installation of Low-Level Bypass (see pp. 12, 42).
