Some years ago I was able to do this at a station that had a similar situation with digital latency. Between the digital STL, digital processor at the transmitter site, and digital exciter, there was enough latency to make it pretty hard to use normal off-air monitoring. Fortunately at this station the aux transmitter was at the studio and the processor for that backup transmitter had solid multiband processing and an analog output. So a Broadcast Tools multi-relay box let me use the muting relay from the console to switch in this processed feed that sounded "right" in the headphones with no appreciable delay. When the mic was off, the regular off-air feed was in the path. Back in the transmitter room, the composite output of Mr. Aphex fed the analog exciter and it was all good.

Great solution Alan!  Feeding just the headphones the processor studio feed!  No relays required.

I'll admit though that it makes more sense to me to monitor the program feed from a production stand point.  We're spoiled with the level of "post operator correction" in modern processing.  If the talent says they sound bad in program or the levels are all over the place, my philosophy is that level control starts with whoever's running the board and then the rest of the chain will sound even better!

Some contemporary processors provide an option for an additional output that is processed minus the parts that cause perceivable latency in addition to the processing going to the transmitter. The Omnia 11 is one such model. It works great for us by setting CR headphone source to that output and all speaker sources use the air monitor and does not require any additional hardware. The announcers can hear the speakers when the mics are off to know what is happening "on air".
