Settings gains and checking RCA distortion with a O scope- what track to use???
Hey guys what's up, I don't a own a dd-1, but there is a local shop in my town that owns a big ass O-scope machine. I'm going to have him set my gains and check for distortion from my head unit . I see people always say to use a 50-60 hz test tone and put it on repeat, but what does the whole 0, -5,-10,-15 db thing mean? Which one do I use, and any links to the tracks?
