Starting another thread so to not hijack the previous one. The output voltage of my Onkyo XLRs are 2.0 volts. Looks like to reach Emotiva's spec maximum RMS output 2.4 volts is required. Was just looking at options. Is there a way to boost the XLR signal voltage to the amps?
I found an XLR mic booster but I don't think this is an option given the near 200.00 dollar price tag to boost one of three channels: www.radialeng.com/product/mcboost
Your thoughts? How much output is .4 volts? I hear others stating that .5 volt is loud. Okay, let's run with that and consider coming .5 volts short of maximum required voltage to reach Emotiva's spec.

Perhaps a real world example, when I am really listening to music I run my XPA-1L’s in Class A, max 35 watts at 2.2 volts input. My listening is at around a measured 5 watts with occasional peaks to 15 watts, that equates to 0.2 to 0.5 volts input. Independently measured XPA-1L at 0.5 volts output is 85 dB. archimago.blogspot.com/2019/12/measurements-emotiva-xpa-1l-gen-1-class.html
I can’t imagine how loud they would be at 250 Watts in Class AB, leaving the room wouldn’t be enough I’d have to leave the house.

The Difference between 2volts and 2.4volts is about 1.6db.
