Thank you for each of your comments. Much appreciated. I have one more question about microphone placement in this set-up, specifically where to aim the microphone? Although hard to tell by the angle of the photo, it appears that Ms. Obama's mic is aimed directly at her mouth whereas Mr. Obama's mic is aimed in front of him with him speaking across the polar pattern (if that makes sense)? I know that overhead booms are usually aimed at the chin, but unsure how to aim it when on a lower stand that is more head level.
Also, I am not committed to the Oktava 012. Other mics I have considered are the Audix SCX1-HC, Audio Technica AT4053b or even stretching my budget a bit for the SENNHEISER MKH 50 or MKH 8050 if convinced they would be that much better than the others. Any thoughts about these choices? Or another specific mic recommendation for this set-up?
Thanks again for taking the time to share your expertise with me. I will definitely take all of it into consideration.
