One problem I just realized w/ my new AVR-4306 is that only one channel pair is assignable, namely the back surrounds. Further, assuming you don't need the back surrounds such that you can reassign them, you must select either
1) Zone 2 or 3
2) Front A bi-amping
Hmmmm... this sucks, because say you have the following setup (mine), which I assume is not terribly uncommon:
- 5.1 (not 7.1)
- Front B's used in another room (in my case, the backyard patio speaker pair)
- Front A bi-amping desired, to take advantage of the beastly Denon amps
Hmmm... screwed, I guess. If I choose bi-amping for the back surrounds, there's nothing to feed the Front B's (patio speakers), other than w/ the Surround B's (only unused pair left on the Denon). But Surround B's amp isn't assignable in any manner, it just outputs surround sound - useless out in the backyard unless I choose special DSP modes every time I want to listen out back (like 5CH STEREO). If I choose Zone 2 or 3 for the back surrounds then I have a cool new backyard setup, e.g., I can listen to anything I want out back while others listen to something different in the house. Alas, with this setup I've now lost my Bi-amping capability for the Front A's. crap.
I carefully read the AVR-4806 amp, it specifically allows assignability of its amplifier stages, so (for example) the Surround B's can easily be assigned to copy the Front A sound, and could then drive my patio speakers.
Anyone have any ideas? Guess I could purchase yet another amp and connect the Front A pre-outs to it, then drive the patio... pisses me off though, to think I dropped nearly two grand on 7 amplifiers that aren't all being utilized. Ugh.
