Hi,I have a sony mzn510 types,and a sony ecm 717 mic.the mic has a long cord.when i plug the mic into the lineout and do recording,the playback volume is very low.even with the recording volume on max and the unit volume all the way down,i still have this problem.Any one out there have any ideas why this might be happening? also the player and mic both have new batteries. thanks alot for the help
