I am looking for a lavalier microphone and think the MX184 would work but am not knowledgeable enough to know for sure if it is the best choice. We need a lavalier because our minister keeps hitting the boom mounted mic with his hands and I can not get him to keep it close enough to his mouth. He does not feel comfortable with it closer than two feet. I also am having a lot of trouble with picking up traffic noise as the building is close to a road. In addition, our minister sits in a chair and the mic is picking up the sound of his sleeve buttons and arms hitting the chair arms so I get a clicking noise along with thumps on the recordings. I use a Peavey 12 channel mixer and do have phantom power available. What mic would work best to reject all extraneous noise?
Of our lavalier microphones, the MX184 (supercardioid) has the most rejection of ambient noise. Whether it will reject everything you want it to, we don't know. Unfortunately, a microphone cannot tell the difference between your ministers voice, the traffic, or the click of buttons, so it will pick up anything it hears.
We suggest you try the MX184 and also try the R185B (cardioid element) on the MX184 body. If neither of these work for you, the final solution would be a headworn microphone like the WCE6. Putting the mic within one inch of the mouth will solve your problems, but we cannot predict if the minister will like the appearance of a headworn mic.
