OK I have an XMC-2 set up as 7 base channels and 2 heights, and I wanted to check the phase on all the channels. With 7.x I just ran a stereo signal on each paired output and moved between the speakers.. with some practice you could detect out-of-phase. Then you repeat for all the left (or right, doesn't matter) speakers, comparing each channel with the main left.

But now I don't have a way to drive the heights... my output device (Apple Mac Mini) doesn't do ATMOS, and I really don't want to move output wires around to do the test... any ideas?

► XMC-2
► Mains: (3) XPA-1L Polk R700 + Polk L400
► Surrounds: XPA TEN-4-3S to (2) Emotiva B1+; (4) Energy Take5 Satellites, (2) Polk Atrium 4
► Subs: Velodyne CHT-12 ▷Twin Energy E:XL-S8
► Sources: ▷NVidia Shield 2019 ▷Sony UBP-X800 ▷Apple TV G3 ▷Roku ▷Sony PS3 Slim
► Other: ▷Yamaha RX-V750 ▷HK AVR-635 ▷Paradigm 7SE MK-1 ▷PSB 300i+500 ▷XPA-1L ▷More Emotiva B1+ ▷Polk RTiA9 ▷Emotiva C2

D'UH! Found a simple solution... well, simple for my setup. I run monblocks on the LCR, and all other channels are into an XPA-10. I can easily switch the monoblocks on and off to control L, C and R, and for the other channels, I can toggle the XLR-RCA input switch, effectively giving me control over each individual channel.
