You're looking for a system solution and that means packaging things
so that they work for you. If you're trying to work with off-the-shelf
hardware, it often means that you end up with more than what you
dreamed about, or you may need more boxes than you'd like to use.
You're asking for the right thing, but it isn't common (or maybe
nobody at all makes it) because it's just not all that much in demand.
Since you have to go into a mic level input on the video camera, and
you want to use a signal source that works at line level, there's
nothing else you can do but attenuate its output. Chances are you'll
still be ahead of connecting a mic directly to the camera input
because the FP24's input stage is probably better than the camera's.

The Jukebox analog input isn't too bad. What IS bad is using it at mic
level. That's very noisy. Since you have two outputs from the FP24,
you already have a split. Connect it as you are, set the output level
so that you get a good recording level on the Jukebox with the
Jukebox set for Line Input and 0 dB gain. Whatever you do, don't turn
the gain on the Jukebox DOWN to accommodate a hot signal coming out of
the mixer. Then attenuate the main line level output of the mixer to
match up with the camera input.
Is the camera input balanced?
