[QUOTE="T3mpest, post: 6857794, member: 560148"] lol a 0db test tone means it's recorded at reference level, 0 decibels below the peak level capable of being recorded onto a cd. a -6 tone is 6db's quieter than that. If a tone at 0db's puts out 1000 watts from the amp, a -6 tone will put out 4000. So yes, a 0db tone is louder than a -6, so gains will be lower with a 0db for the same output. If you set gains with a 0db tone, your gains will be very low and you wont' see much power out of the amp on any tone other than a 0db peak on a recording. setting at -3 or -6 means you'll get close to RMS power at the normal parts of the song. SPL guys set gains with tones because they are pushing things to the absolute limits and will be burping with that exact tone. Granted I come from more of a SQ oriented mindset, where people know how to properly use their equipment and dont' tend to overdrive things constantly. If your that scared, use a 0db tone, just dont' wonder why that that tone got loud but as soon as you pop in a cd, everything is quiet. Techically anythign other than a 0db tone will probably clip part of the time, but that also guarantees you'l never see alot of the power from the amp either.
