BAT VK-52SE - Unity Gain/HT Bypass help


I could use some advice in getting this to function correctly. I have connected balanced interconnects from the processor out to the Aux 2 input on the preamp. I have selected Aux 2 in the programming function and set the unity setting to "fixed" and left the volume at 000 (also tried 001). When I run from the processor (with preamp on, not muted, and Aux 2 selected) I get nothing out of the mains (which work correctly in two channel). Anyone have advice?

The volume setting on the BAT 52SE still has to be matched to the processor and other sources, so the processor volume control can operate normally, as if the BAT wasn't in the loop. I have my 51SE set at 110 (step mode).
This is strange. Does it work if you don't set Aux 2 to fixed?

Also which processor are you using? Is its output RCA or XLR?
It does not work when set to not fixed. The processor output is connected via XLR. A different preamp (different brand) with a HT bypass works perfectly when connected to the processor. I guess that tells me what I need to know.
