When I was running an AC station, I programmed the box for a pretty consistent sound. I wanted a good, rich, warm sound, but was processed in a way that it was very transparent.
Gotta remember that AC radio is meant for high TSL. If you have heavily processed audio, it can lead to listener fatigue.
Best advice is to scan around the dial and listen to how other stations in your area sound. Find one you like and tell your engineer. They can listen and try to match the sound.
