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

Bob, OK, so you are firmly in the camp of processed sound, if done right, sounding better. I'm ok with that (I think Kal at Stereophile agrees with you too). Of course I cant agree or disagree as I've not compared it much, but assume you have and to your ears processed is better? Clearly there are two distinct camps on this, and as always, only your own ears will tell you what you like. Some people firmly believe that room correction is the only way to hear music properly. However, I think the argument on pre/pro vs preamp assumes a certain level (pun?) playing field and, given such, a preamp provides a better, cleaner, clearer picture than does an average pre/pro. Again, assumption on my part from reading forums. No doubt that, in a poor room, processing/correction can probably make a bigger difference and provide better SQ than a good preamp.
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.
[From the description, it seems that Jeff's original idea of a line level switch box would be a simple solution. Decware's box comes to mind]

No, actually, according to Barry, just connect the two units directly to the sub: pre/pro LFE out via RCA to sub, and preamp L/R out via XLR to sub. Just dont send signals out from both units simultaneously!
