i purchased a crown CE1000 to run my SVS 20-39CS+ and was just wondering where other people have the gain control set after calibration. right now i have it about halfway after calibrating by ear. my friend will be returning my SPL meter and calibration disc soon and i will be calibrating it correctly and i just wanted an idea of where to start. also in general, i have read some different methods to calibrate. once i read that pro-amps are made to have the gain turned all the way up (to let the mixer/reciever control the level). ive also read that you should turn the recievers sub level to -4 and then adjust the gain accordingly, and also to just turn the gain to 1/4-1/3 and adjust through through the reciever. needless to say, im a bit confused and would love some clarification on the calibration on this. i also felt that the subwoofer forum was more appropriate than the amps forum (though i did originally start typing this up for that forum).
