Been debating acquiring an omni mic just to experiment. Been having some really great success with cardioid condensers over the drum kit so I know my abilities with them. Really considering putting a single omni up?
Why do you think an omni would be better? It will pick up not only the kit, but everything else onstage, the reflections off the ceiling, the wedges, and anything else that might be in the air. If you want to go with a single mic, try one of your cardioid condensers.
Also I run into a few speaking engagements a year and one in particular the folks do not provide consistent volume into the microphone(s) thus causing things to be pushed in search of providing adequate volume levels. As I am always on the quest to find the best solution with the best outcome as I am sure we all are I ask the question would an omni mic provide a better solution?
An omni does not smooth out level problems. It just picks up in every direction fairly evenly, where a cardioid picks up mostly in the direction you point it. For use on a lectern an omni will generally be worse than a cardioid in marginal GBF situations.
I have a monitor at the podium but is very low in volume.
What is in the monitor? If it is anything but audience Q&A mics lose it.
Last year I ran an SM57 and considered a pair this year. The year before a Sennheiser e835 which did not work all that well. The issue is once the event starts its 3 hours of none stop lecture, comedians, etc. Have the offer to get an Audio Technica Atm10 for pretty cheap and thought that may be a good experimental option. Thanks for any input drum overheads/speaking.
Stick with the 57s, or go for a gooseneck lectern mic like a
Countryman IsoMax 4 (the best) or a
Shure MX412 (still pretty good). An omni has little use on a drum kit or a lectern.
