I would say that I am an audio novice but that would be an egregious overstatement. What I am searching for, if any exist, are general rules of thumb regarding PZM microphone placement in an open room. More specifically, I ordered 2 PZM-11LL mics for use in an open-air voice recognition system. I pretty sure that this is a ‘that depends topic’ where everything influences everything else but I need a starting point of some kind. I have bookmarked the technical resource documents on the Crown web site have not had time to read through them yet. Also, I have been told that the room I am in is a worst case scenario with flat walls with nothing on them, hard wood floors, a 12 foot ceiling, and measuring in the neighborhood of 12’ x 30’. I know this is probably going to be a lot of trial and error work but want to at least eliminate the ‘audio common sense’ variables.
Should the mics be installed at wall switch height, head height while sitting, while standing? Is there any variance to where the mic is in relation to the voice? For example, is it better to speak directly at the mic or would work as well with my head pointed 30 degrees to one side? Would it be better to have one 3 feet behind my head or 15 feet across the room?
What about a mixer? I currently have a cheap $40 mixer (you can probably guess where it was purchased) which helped while trying to use all of the wrong mics but have to believe that there is a different one at a less than heart stopping price somewhere. I’ve heard of people using automatic mixers. Is this the silver bullet that the name implies?
See, audio novice is an egregious overstatement!
Thanks in advance,
