Hi I am a newbie in the Dolby Atmos world! I have the new Onkyo NR656 AV receiver. I was thinking of getting the Onkyo Atmos add-ons to sit on top of my front speakers. My question is - where do I connect these speakers in the AV receiver? My current setup is 5.1 and have the option to go to 7.1. Do these connect to the 7.1 connectors?
