EAS feedback from mics.

[shnar]

So I just installed my EAS system (only took me a year), and everything is working, but when I turn the volume up to even know settings, I get the feedback scream from the mic. Did I install the mics to close to the speakers? Is there a way to isolate better with say foam or do I need to move the mics?

 

You can see where the mic is here. I put it there based on a tutorial I saw a while ago, liking the idea it was hidden by the band.

Bryce,

 

When I installed mine, there were a few things that I found helped.  First was that I turned the volume up until I just barely heard the squeal when my head was not in the bucket.  When I put it on, I found that it was just about the perfect volume so that with my head in the bucket, it worked perfectly.

 

If that isn't enough, then yes, looking at your pictures, I'd say that a physical barrier between the speakers and the microphone would likely help.  I have my fan batteries directly in front of my speakers and that makes a world of difference.  I originally had the speakers in front of the batteries, and it was almost impossible to stop the squeal.  I switched the two and that was the perfect solution.

So, try some foam, as you mentioned, and see if that makes a difference.  I suspect that a 2x3" foam block in front of each speaker will solve the issue for you.
