Hello, I wondered how exactly to match tp's xlr to rca volumes: - xlr has 3vrms meaning a sine wave produced via xlr has +-3 volts right? Whereas rca has 2 vrms meaning that the amplitude is by 2/3 lesser than with xlr. This would if for example 36db are twice the loudness of 30db indicate an increase of 3db between xlr and rca. Well, but power and therefore sound presure leves are proportional to the squared voltage. The area below a sine wave of 3 volts amplitude is far bigger than just 50% than a sine wave with 2 volts. So, what is right now? I am not experience in electronics but perhaps someone could enlighten me?
