Bi-amping for HT

If my current Pioneer had pre-outs for the speakers then I'd be set but it only has the pre for Subwoofer.

So just to clarify, I need a new HT receiver that has pre-outs for the front speakers(most current ones have pre-outs for all speakers). Connect the Pre-out L&R fronts from the HT to an Aux input on the SP12. Run my normal connection from the SP12 to the D90 amp. I don't believe it has a bypass mode.

I would have to manually turn on the SP12 because of no remote, with it set to the Aux input. Set volume to a predetermined level and from then on I can run the volume for all HT speakers from the new HT receiver remote.

Listening to music only with just the fronts and SW would be done as normal using only the SP12 and D90. I could listen to music in 4.1 if I connect my source to the HT so the fronts would go through the SP12 but the rears would be handled completely through the HT receiver. I could hook a different source into the SP12 and use just 2.1.

And if I get tired of the manual switching I can upgrade the preamp to one with a remote function and possibly a bypass function.

you got it, except unless you have a subwoofer connect to the SP12, it will be 2.0

Cool!
Thanks a ton.

Jamesk58, you can use a A/B speaker switcher on your speaker to select HT or 2channel system.

Set the SP12 to unity gain each time you use in setup in HT mode.
