yeah, totally! just buy a battery box and boom you'll be set. plug the mic you have for $60 into the battery box, then plug the battery box into the NJ3 hole.
http://www.soundprofessionals.com/cgi-bin/gold/item/SP-SPSB-1this is all you need. it runs off a 9V battery .. the 9V will last for years and the thing will give your mic enough juice to record a great signal on your nomad. you're close! and your old man will really appreciate it.
