How to hook JL F112 sub to both preamp and pre/pro

OK, so I impulsively bought an F112 sub. WOW. Great for movies via LFE sub out from Sunfire pre/pro. However, cant engage sub when I use source direct mode, which bypasses all processing. Sub only has line level input. Been thinking about buying separate 2 chnl reamp with HT bypass anyway, but not sure how I would hook that in. Maybe a line level switch box, where I would send the LFE out from the pre/pro and also sub out or second set of L/R output from preamp ansd switch them as needed? Is there such an animal, or any other ideas? Thanks...Jeff

I do this right now with an Epik Valor sub.

RCA from the AVR to the LFE input and L/R Line level from my MF A5 Int amp L/R preouts.

For Movies, the A5 is put in the HT Bypass and the preouts become disabled and the AVR drives the sub via the LFE input. Bass Management is via the AVR.

For Music, I turn off the AVR, and use the MF A5 with source components - and the sub is driven from the A5 L/R preouts. "Bass Management" is via the xover cutoff on the back of the sub.

Works just fine.

A pre/pro is a swiss army knife that is great for doing a bunch of stuff at the sacrifice of doing just a couple really well.

I'd prefer a high end preamp/amp and take the extra time to do my own sub integration.
