Wow, I didn't know Fender made a 24 channel mixer. I did a couple searches and didn't find anything on it.
Anyway, if it doesn't have dedicated direct outs on each channel, you can use the subgroup(buss) outs to feed the recorder. Sometimes, you can also use a channel insert as an output by inserting the 1/4" plug in to the first click. Not the best situation, but it can work to get you started.
As far as outputs, if all the recorder has is left/right stereo outputs, you are pretty much stuck mixing your tracks with whatever mixing facilities that are built into the recorder.
Good Luck
