I know what you are trying to do, I have the same requirements. I found the XLR-PRO from Studio 1 work much better than the Beach adapter that has been recommended. It has 2 XLR inputs and 2 - 1/8" inputs, along with a Stereo/Mono Switch, which allows you to set the XLR-PRO up so that input 1 records on the right audio track and input 2 records on the left audio track. When you put the unit in the Mono mode you can use just 1 mic and have it record to both the L & R audio tracks. Here is their web site address if you want to find out more about the XLR-PRO. http://www.studio1productions.com(posted 9157 days ago)I tried the Beach unit, but I had 60 cycle hum pickup when using the camera with the AC adapter. Also, from time to time I seemed to pickup zoom motor noise. I have never had these problems with the Studio 1 model. Mike, MTW Productions
