Question 1

can I select more than one zone at a time also do I need separate volume controls at each zone

Accepted Answer

This is actually one of two parts,  think of this as the power for each zone.  The zone and source audio controls should be run through separate multi audio controller.  For a better understanding the latest is the Nuvo line by Legrand. build several houses and restaurants running amazing audio on this multi channel amp.  Clients love it so far.   Just watch out for the eco friendly  auto shutoff.  If there is no audio signal it shuts down goes red on the amps,   It comes back on when audio signal is turned up/on and does take a  5-19 second warm up to bring sound up, then you get blue-lights and all is good.

Question 2

Can I connect another amplifier to this one to power one more room? I believe the term is daisy chaining.

Accepted Answer

I did not do it that way. Instead I used Sonos products with 3 of these amps to power about 40 speakers, two separate Pioneer amps, TV's, FM radio, laptop computer, and a Bose CD player. It worked out great for me. Before I bought the amps I contacted customer service at Dayton. They were really knowledgeable and helpful. I suggest doing that with any specific question. These are great amps and I highly recommend them.

Question 3

Will this drive 16 speakers @ 8 ohms?  Forgive my ignorance but I am confused if 12 channels means 24 speakers (12 pairs) or just 12 speakers (6 pairs

Accepted Answer

12 channels = 12 speakers.  Two channels per zone, there are six zones.  Don't let the 40 watts fool you, it is more than enough power for ceiling/wall speakers to get loud.

Question 4

can I power 5 different rooms each with its own volume controller?

Accepted Answer

Yes.  However the position on the rear of the unit and their small size makes them better suited for initial trim and adjustments rather than constant altering.  I controlled 6 rooms with mine and the volume was always handled from the smartphone that was AirPlaying to that room.
