Samsung smart 4K TV, Marantz AV7702 Pre/Processor, Oppo BDP-103D BlueRay/DVD/CD, Cisco (Cox) 9865HDC
The above components are the backbone of a 9.2 + Atmos system. I want to control the four components indicated with the Harmony 650. Is there a way to determine, in advance of purchase, if the 650 can do this?
