you get it.
ok, i dont know what kind of RME you have, if you have 1 with a breakout box are only a card.
if you have the 1 with a breakout box you can use the volume knob on the RME.
if you dont have the breakoutbox RME ,you have 2 use your amp.(or buy a stepped attenuator)
Now run the pink noise, have your SPL meter in your hand where you wil be sitting when you wil be doing your mixing.
have the SPL meter in Slow,C.
now turn your amp up with only 1 monitor running. until it reaches 83 dbspl.
do the same with the other 1.(both wil sum and wil get you 85 dbspl.)
now put a mark on your amp where the pinknoise reads 83 dbspl. this is now our 0 monitor gain point.
you can do the same calibration but for K-14 but now you its 77 dbspl per monitor
and 79 dbspl combined.
now you have a new refrence point that is lower then 85 db spl (monitor gain 0 db)
and that is 79 db spl (monitor gain -6 db)
you said that 85 is 2 loud... you can mix at around 75 db spl and stil get good results.
but the fletcher-munsen curve is its best at 85db ,the human hearing is there flat(so 2 speak  ) .
if you go lower you wil hear almost no bass response ,if you go higher in spl the highs wil be exadurated.
it also has 2 do with ,how big is your room.
PS: you only have to calibrate your setup 1's.
because you now you have your refrence points. 0db and -6db. on the amp(or on the stepped attenuator) good luck with your calibiration, hope this help'd   |
sorry guys.. still cant really get the calibration fixed. i followed Ravian's instructions as above and everything worked out fine. However, i hooked up a mackie mixer and had my ipod (max volume) playing the same -20dbfs pink noise file, with everything at unity on the mackie, i tracked it into my rme.
I pushed up the trim till it flutters around 0db on the mackie mixer. everythings good BUT
Readings from my setup.
Totalmix reads around -25dbfs RMS
Cubase reads around -15dbfs peak (doesnt read rms for some weird reason)
and digicheck reads -5db (Vu) peaking at 3 to 4 db.
Now im getting seriously confused here. Am i doing anything wrong anywhere? What should i do to get the meter readings right?
i tried doing it the other way
2) if i played the same -20dbfs pink noise track thru cubase. everything reads fine.
Total mix reads around -19dbfs RMS
Cubase peaks around -25dbfs
Digicheck reads 0db (Vu) and i suppose everythings okay..
BUT i tracked it back out into the mackie mixer and it reads only -10db. Shouldn't it be reading 0db? am i missing something ?
Please help anyone. Appreciate any kind response. Hope im not confusing anyone , tried my best to explain it as clearly as i can.
