Hi,
Does someone can help me to understand this?
After EQing, to calibrate the SPL of each of my 5.1 channels to 75db and to adjuste relative gain of each channel (+ or - db) into the receiver, I usually playback the test tone of the receiver (see My system). Here the result:
FL= 0db
FR= 0db
Ct=-1db
SL=+1db
Sr=0db
forget the sub for the moment.
Yesterday I tried with REW's pink noise generator and the SPL meter in REW (Umik-1 mic calibrated 90degrees file). I adjusted the main volume of the receiver to get 75db on the FL channel and the gain to 0db into the receiver. Then,via hdmi and ASIO4all, test all channels. Here are the results:
FL=0db
FR=0db
Ct= -4db
SL= -5db
SR= -2db
It improved the SS&I greatly !! Way better, more envelopping !:surprise:
is it possible, logical, in accordance to home theater sound theory or are my brain and my ears tricking me?
I read elsewhere that someone uses only dvd with pink nois to calibrate SPL channels.
Can we trust the "quality" of the test tones of our AVR? Is it always better to playback a test tone via the bd player? or via REW?
