About a year ago I built a small office addition to my house. As it was all new, I wired it for a 7.2.4 atmos setup but didn't have the money for an 11.2 receiver at the time.
I had a Yamaha RX-V570 which I was able to use for a reasonable 7.1 sound, but last weekend I managed to pick up a Yamaha RX-A3070 which, in theory, would allow me to use all 11 speakers in Atmos 7.2.4 setting..
I have managed to get the A-3070 working on 7.1.2 (front atmos being the last powered speakers) but you have to use the pre-outs from the A3070 into another amp to get the final 2 rear atmos speakers working. I've played around with the RCA out from the A3070 into the RCA in for AV6 on the RX-579 but no joy getting the rear atmos speakers to work or sound the test tone and yes, the a3070 is set to the pattern for 7.2.4 with the rear atmos set for external Power Amp.
Any thoughts on what I'm missing? Is the RXV-579 capable of acting as a power amp? Using B&W M1 mkII's for all 11 speakers for now. All speakers working if I plug them into the Front L/R jacks, so no problem with the wall wiring or the speakers themselves.
Help appreciated
