so i see this sync solution with the olympus stereo mic to get on board sound (http://www.bhphotovideo.com/c/produc...icrophone.html) and i have a rode video mic (http://www.bhphotovideo.com/c/produc...a_Mounted.html)

ive been told i need a stereo to mono adapter to get my rode to work with the scarlet but i dont understand how this mic works cause it looks like stereo plug also just like my rode. what am i missing here?
