Help with connections with my new audio/home theater setup

The top set of terminals go to the Atmos amp. The bottom terminals feed the front drivers and go to the 2 channel amp.

Take the front L/R preouts from the AVR into the Aux input on the amp.  When you set the channel balance for HT choose the Aux input on the amp and choose a reference volume level on it that’s easily repeatable (I used the 12:00 position) and set channel levels as usual.  Plug your 2-channel sources into the amp and hook it up to your speakers and you’re good to go.  When you want HT select Aux on the amp and set it to your reference volume point and the AVR controls everything as normal — just remember to turn the volume back down on the amp when switching to 2-channel to avoid a sound bast, or you could choose a lower reference volume level initially during channel balancing instead of 12:00 that would avoid this problem.  Alternatively you may be able to use the amp’s tape monitor input instead of Aux that may take the amp’s volume control out of the picture, but I’ve never done that so can’t go into detail how/if that works.  Hope this helps. 

thank you so much for the info. I appreciate it. I will let you know how this comes out. many of the challenges are because of not having all of the correct length cables, so I am going slower as I set this up. thanks again.

Hi:

I am looking at RCA cables for this. Or should I be using a different type of cable? I saw something about an interconnect cable. Is that something I should consider? Thanks!

An RCA cable/interconnect (same thing) is all you need, just make sure it’s long enough for your needs. Blue Jeans, Canare, Mogami among others make decent interconnects for not much $$$ and should be fine for this application IMHO.
