Mono Output

[ChrisConklin]

Hey this has been racking my brain, i'm going to get a single Avantone Mixcube as a reference monitor so i can check my songs in mono. The cable i currently have laying around to use would be a stereo 1/4"TRS to XLR (wanting to use it as only mono though obviously).

I use my Virus as the soundcard through USB with Ableton. I use output1 on the virus for my main monitors.

I was hoping i could somehow plug the mixcube into the headphone jack instead of having to unplug a main monitor everytime i wanted to check my mono summing.

I'm thinking i need to put a mono VST plugin on my master track in Ableton which would output a double mono correct? (there is still L+R information but each channel is identical).

So if i have my stereo cable plugged into one speaker, will that output the double mono from my DAW as just normal mono on the Mixcube?
