Denon AVR-1913 Zone 1 and 2

I am new to multi-zone speakers using a receiver because my old house had multiple Sonos boxes so it was easy to understand. However, my new place has speakers already installed in 5 zones of the house. I purchased a Denon AVR-1913 and a RTI AD4 for the distribution. However, before I set it all up I have a basic question - In my living room I have a 5.1 system. I would like to use this as Zone 1, but then connect all of the other rooms (via the AD4) to Zone 2; does Zone 1 and Zone 2 play the same thing at the same time? Meaning, if I am listening to Pandora on the 5.1 and want the rest of the house to broadcast that exact same music, can I just link Zone 2 to Zone 1?
