Thanks to your help previously I am now more informed and more advanced in my planning.
To recap ....
I have a Denon 3805 Amp, and SHE requires multiple inputs to go to multiple outputs.
With your input I had decided on using the main room as 5.1 and the other two areas (dining and patio) from the other two stages using impedance matching volume controls for the dining room and patio.
Now SHE says "Can we get sound around the pool area ??".
From what I now know the answer is "Yes, either use another impedance matching volume control (splitting the output 3 ways) or connect an old Akai amp I have to the Denon Zone 3 output.
I can see advantages and disadvantages of both the "three-way impedance matching volume control plan" and the "add a second amp" plan ......
Is there any RIGHT way to do this, or conversly, is there any WRONG way to do this ???
