Can you bi-amp using 2 sets of pre-outs?

My AR LS-10 has two sets of main pre-outs. I would like to run the Carvers to the low pass on one set of pre-outs and the Sunfire on the high pass to the 2nd set of pre-outs. The speakers have an internal crossover.

Preamp..............Audio Research LS-10 solid state (no phono input)
Preamp..............Carver C-19 Tube (I have it connected to the AR LS-10 and use it for a phono preamp)
Speakers............Infinity Kappa 9
Amps.................Carver Silver 9-t monoblocks
Amp..................Sunfire Signature
Phonograph..........Oracle Delphi Mk-I
