I just don't seem to have the time to learn REW right now, so I want to start with the manual method and download the SPL Calibration Spreadsheet on the download page of this forum, along with the Test Tones.
I have a few questions on this manual method.
1) My system is calibrated for 75dB (when master volume is set to 0). However, how do I know how loud to turn my master volume to begin doing the manual tests? Do I play a 1000Hz or a 4000Hz signal and adjust the Master until my SPL meter reads 75dB, then use this Master Volume level for the remainder of the Test Tones?
2) I assume the Spreadsheet in the download section automatically changes the calculations based on the corrections for the Radio Shack SPL meter? So, I put in the EXACT number that my SPL meter reads, and the spreadsheet will adjust accordingly? Or, do I need to do some sort of calculation before I enter it into the spreadsheet?
3) Where on the spreadsheet do I enter my SPL readings.....the Light Blue (RAW SPL) column or the Orange (RAW SPL BFD) column? I plan on purchasing a BFD at some point to EQ my sub based on the curve from this spreadsheet.
Thanks, and if I put this on the wrong thread, please let know.
