Hi all,

I'm considering installing a pair of M3 ceiling speakers in a 5.1.2 configuration to enable basic Atmos sound in my home theatre setup. My processor has the needed outputs for Atmos but I only have 5 channels on my ADA-1500 amp.

I am reasonably sure the answer to my question is "Yes" but do I need to upgrade to a 7-channel ADA-1500 to drive my intended setup? I don't have room for 2 amps so adding a second ADA-1500 to drive the 2 Atmos channels is not an option. I could always replace the processor/power amp with an 8 or 11 channel integrated amp but I do want to stay with a Marantz prepro/Axiom power amp solution.
