khollister any insight on my yammy outdoor speaker scenario on zone 2....dont everyone chime in at once.
I don't use zones (only use the AVR to drive the theater), but the 3312 is only 6 ohm rated I believe. Running a single pair of those speakers might be an issue, let alone 2 simultaneously.
I am not personally familiar with the Niles box, but a quick glance at the Niles web site indicates it has some impedance transform capability for paralleled speakers, but I still think the amp is going to be presented with a 4 ohm or lower load with 2+ pair of 4 ohm speakers connected. It is also not rated for the full output of the Denon, but that is probably not a huge concern unless you need to invoke the warranty.
The safest approach is to use the zone 2, zone 3 pre-outs to drive a 4 ohm stable external multi-channel power amp, but that is likely to be cost prohibitive.
Of course this all might not matter if the 6 ohm rating on the 3312 is just due to current capacity - since the outdoor speaker will likely not be running at reference levels, it is possible at least one pair could be driven without the over-current protection tripping in the Denon.
On the other hand, if the amps are not stable at 4 ohms, you could nuke the amp and the speakers worst case. I have no information as to what the reason for the Denon rating is.
