Using a jack to jack cable, plugged in the zoom h4n to the d800, made a short video and there was a lot of background hissing when played back on the camera. Any suggestions.

If you're using a dslr and a zoom then you're shooting in a manner known as double system.
You don't connect them together. You record separately and get two files. You then replace the camera audio track with the Zoom audio track in post production.
