i used to have for my main 3 speakers (LCR) 2 pa amps (crown xls 1500) after changing them for 3 mono tube amps (140watt each) the reference level changed.
with my old set up i used to have 105db at 0. now i am having 105db at -6db from my avr(onkyo 876).(in the same scenes)(without the use of the subs)
i want to mention that i am not using dynamic eq and the test tone from the avr is 75 db as it was with my old set up.
can you explain me what is happening? is it because of the headroom of the amps?
thanks in advance
