Hmmm, @Wynnd, are you a singer? A lot of us singers explicitly want reverb on our vocal monitors, especially for in-ear-monitoring. Gives better feedback on what we are doing - and gives us kind of a comfort blanket ;-) Singing with a dry in-ear signal feels a bit like singing in a completely dampened, "dead" room - creepy!
Of course, it's different if you sing with a classic monitor wedge on a sonically active stage with sufficient reflections - that may be enough to feel good with a "dry" monitor signal - especially if the feedback from the room gives you an additional reverb tail.
On the original poster's question: the reverb effects on the DL series are "send effects", i.e. all channels can send input to the reverb, which then processes the sum of all inputs. The output of this reverb then goes to the main LR output, and you can also enable it on your aux channels. But of course the reverb signal then contains the processed reverb from ALL signals that send input to the reverb.
If you had multiple reverbs (as on the DL32R), you could get around this by dedicating one reverb only to your egocentric lead singer (this means using a different reverb send for that singer) and having everybody else use the other one, but since your DL1608 only has one reverb, this isn't an option. So if your male singer wants reverb on his monitor, he'll have to live with the reverb signal of everyone else in his monitor.
Of course, you could also plug a separate reverb processor into the path from the DL1608 to the guy's monitor, so he has a dedicated reverb for his monitor, but I'd consider this a bit of overkill, especially in a pub setting...
Cheers,
Torsten
