The Sunn Beta has 1.75v P-P out at the master line output, but each individual channel has only 1.1v P-P at the preamp line output.
Sunn Beta basically has 3 effect loops.
If you made a single channel the output to the power amp is only 1.1v P-P which should be ok, and you don't have to crank the volume pot all the way around.
If anything you might not get enough signal to drive the TPA chip to full power since the Beta figures are peak to peak.
I think it should be OK. The TPA3116 has gain from 20 to 36db. I haven't done the math to verify, but I think this should get close.
