i recently got access to a sony digital camcorder, and am going to take it
up for a flight (passenger recording of course), and i wanted to patch in
the intercom to its audio inputs. What is neccessary to adapt what comes
out of the intercom to make it suitable for line level inputs to a
camcorder? If anyone has made such a cable, or knows a place that sells
them, i'd be interested in hearing from you. thanks.

If you pull a few key words out of your post and Google the r.a.*
