IIRC, no "Room EQ" was globally done to any of the stacks. The processing basically amounted to whatever preset crossovers and system EQ's that the owners had programmed into the rax & stax; nothing was added at the board. Some systems, like the SRX/VRX combo and the JTR rig, didn't have any rig processing except for the electronic crossover. All the system listening tests were done listening to a John Hiatt track for about a minute; then a system discussion and Q&A and on to the next rig. There were 9 full-size rigs and 3 mini-rigs (self powered) there, and a few variations of the 9 rigs were tested (for example, swapping out a QRX 153 with a QRX 212, both over a QRX 218).
The monitor listening test was Trace Knight barking into 13 different monitors, one at a time, with a Sennheiser (IIRC) vocal mic. Correction - I think #12 was removed before we could get to the monitor session b/c Dan Nickelski had to leave early and remove it from the running. There WAS a 100 Hz hi pass applied at the board to all monitors. They were all run in passive mode, which Trace said impaired the performance of his EAW 260's which he usually bi-amps.
