Need help, 2 zones 1 receiver
I currently own a Denon avr-s510bt which supports up to 5.1, and its set up sort of in a wrong way... I have 2 speakers working as surround, in the back of my living room + subwoofer in the front, next to the TV. Then, I have a terrace, in which are located 2 more speakers. So, in total, 4 speakers, 2 in the living room and 2 in the terrace area. I never use them playing 2 different things at the same time, mainly the terrace ones I use for music when having parties and the interior ones, I use them for movies. The problem is: I want to properly setup a 5.1 in the living room, while, ideally, adding one more speaker to the external area, that in total would be 8 speakers, 5.1 in the living room and 3 (ideally) in the terrace area. However, I think my receiver does not have enough ports for so many speakers. Should I buy another receiver or is there a cheaper way? If yes, what type?
