Just checking, but it appears that this receiver can do both a Zone 2 and a 5.1 setup with bi-amped fronts simultaneously. Is this the case?
The RX-V661 has 7 channels of amplification. You can use this amplification in many ways:
- 5.1 + Powered Zone 2, No biamplification
- 5.1 + Externally powered Zone 2, Biamplification
- 7.1 + Externally powered Zone 2, no biamplification
So to answer your question, I don'k think RX-V661 would power both Zone 2, and Bi-amp the from speakers. The receiver has 7 channels that will handle 5.1, plus 2 more channels (Zone 2), plus 2 more channels (bi-amp), that brings the total channels to 9.
The RX-V661 only has 7 channels of amplification. It could be done if say the reciever was able to use 1 channel for Zone 2, and slip the left over channel into two for biamplification. This is however just an "artists" conception of how it would work with no real engineering logic applied to its actual operation.
Let's not forget also that the RX-V661 has the included presence channels that Yamaha used to only include on its high end receivers. I have yet to hook them up (to many speakers), but I did have them hooked up to my Yamaha RX-V1 when I owned that unit and the presence channels were a definite benefit. Rightly so I believe since most movie action and information is in the front sound stage.
