Hello all. I am having some issues with my audio recording. I mainly do wedding cinematography and some documentary films. I normally use a lav wired mic to a Marantz PMD620 recorders. I do my audio check each time and normally record level is normally around -06db. What I am noticing is that the audio records fine, but if at any time the speaker increases their voice to a higher pitch, you can hear somewhat of a squeal (not sure if this is the right word) vibration kind of sound. What can I do to avoid this from happening in the future? Any info appreciated. Thanks
 
What do you mean from of house? By speaker I mean the person I'm interviewing. If it is feedback what I'm having, how can I avoid it? Thanks again
 
Oh so it is a person to person interview setting and not the ceremony then? Feedback is when noise/audio enters the mic and out to the speakers and back into the mic and out the speakers etc. etc... This can happen when the mic gain is too high or speaker (PAs, monitors, headphones, etc.) are too loud. Theres a lot of ways to prevent feedback, idealy by turning down the volume, or isolating the mic, or simply point the mic in a different direction. So depending on what your setup and conditions are like, there are many many solutions.
 
Thanks for your help. I will get a sample online for you to hear what I'm referring to. Will repost when complete. Thanks

"Speaker" as in "a person who is speaking" NOT as in "a transducer for converting electrical energy into sound." As I understand the original post, this is NOT in a PA environment. With no loud speakers in the equation, feedback isn't going to be his issue.
 
I apologize for the delay. The zip file is 2mbs. Any suggest website for me to upload to share the link? Thanks
