Hi Y'all.
I found the answer to my issiue for a external mic .
The L2 uses a stereo mic, so i had to get a stereo mic with a 1/8 jack on the end.
i got the Audio technica pro 24 from american music supply.
i also found out that the other cable on the canon mic that came with the camera is the power cable, thats why that mic works without batteries. I also found out from these great guys
http://www.studio1productions.com, that you can use any handheld mic and get a stereo signal if you have a stereo xlr audio adapter.
I don't know why no one on this site could tell me how to do this (record stereo audio from a handheld mic).
anyway case closed. :)
