HELP about preamp and processor


There is a Jadis DPL2 with tape in and tape out for audio sessions and a thule home cinema surround preamp for the cinema sessions.
The question is how can I use them both for each task ?

Thanks.

One would run a pair of ic's from the processor's "fronts-out"-(l&r) in to this "tape-loop" input of the Jadis. One would also have a pair of ic's coming from their dac---those go into the "cd-input" of the Jadis. So,--for 2ch you would use the "cd" input for 2ch and the "tape loop" for HT listening.
