I am looking at picking up a Velodyne DD-15 as a possibility, but had a question about how to handle my configuration. Right now, I have two preamps that share the Front L/R speakers. My HT prepro is a B&K Ref 50 - on the HT inputs (Dish/DVD), it routes the Front L/R to my music Preamp (PS Audio PCA-2) which uses the HT bypass to let the signal go to the speakers. I have a sub that I use in HT settings only and is connected to the B&K sub output. I currently have the Front L/R pair running as Large (full range).

If I purchase the DD-15, I wanted to run them for HT and music. I know that you are only supposed to use one of the inputs on the DD-15, so I was wondering if the following would work:

1. Use the B&K for HT and set the Front L/R speakers to small and then have the B&K use the XLR output into the DD-15 input.
2. Use the PS Audio PCA-2 secondary output RCAs and have them go to the DD-15 RCA inputs.

When in music mode, the DD-15 will not see the B&K sub output, since there should be no signal on it.
In HT mode, the small setting of the Front L/R should mean that no sub 80Hz info makes it to the DD-15 and that the sub XLR input should have all the 80Hz and below signal.

My restrictions are that I cannot require wire swapping to switch between systems and I cannot support 2 subwoofers in my room or budget. My hope would be that I could select input by remote and then tell the DD-15 which channel to use.

I am sure that my setup is not unique - anyone else solve this dilemma? Help!
