Which Microphone does support to ADSP BF-706 EZ Llite kit?

Hi,

I am currently working with  ADSP BF-706 EZ Llite kit . i am facing problems in interfacing microphone to EZ Kit. can you tell us which microphone is supported for the kit. and should we use stereo microphone or mono? when i connected microphone it was not capturing anything at J1 pin(Line in).

Thanks and Regards
