Hey guys thanks for the reply!
eotsskleet: We tested with the Template LR. We have replaced the leads from sockets and tried 4 different output sockets with the same results.
Chris93: They are new processors. For testing we have audio running into inputs 45/46 on the GLD-80 surface straight to the “Main LR”. Main LR is coming out of output sockets 1 and 2 on the AR84 expander, into AT Blackbird processors, one for each channel, which feed into 4 channels of AT HD7 Amps each. Those amps are running 6 cab hangs on either side.
