I had this product sheet on the psp-3 and wanted to let others have aread if they were looking for info on it....plus you can go to this link
http://www.posthorn.com/Aeta_3.html.
Personally, if I owned one of thses I change the gain setting to about 15 and 30dB..reducing the noise and making it suit my needs.
hope this is informative to those looking for psp-3 info. It's a nice set up but for the price you can get a used MME
peace
