Hi Santa,
it's been a while since I actually tried audio recording. I recorded a few sequences in the early days before I sold my 9000 pro.

From memory, I connected the pro's "audio out " to "audio in" on the kn7. {so I had the pro playing through kn7 speakers}
I connected my kn7 to my laptop via a usb cable.
I then used the audio recording software supplied with the kn7 ( you'll have to read instructions), but instead of hitting play on the kn7 , I hit the play button on the pro, and recorded it to the audio software. I think it somehow uses the kn7 as the sound card instead of the computer soundcard.( I'm not teribly computer literate)

You'll end a with an audio file.

For saving that file to sd card and converting it, you'll need the panasonic sd pc audio writing kit, which consists of a special type of sd card reader/writer and the Juke Box program.
A card reader is pretty much a "must have" anyway, as it saves a lot of time when doing backups from sd to computer.

There are cheap sd card readers available thru computer stores etc , but they won't work with the Jukebox program & audio files on the kn7, so if you're planning on audio, go for the panasonic sd writing kit.

best wishes
Rikki
