4.6.6 Mixing Level (pg. 4-42)
====(start of partial excerpt)
"This parameter indicates the absolute acoustic Sound Pressure Level (SPL) of an individual channel (usually the Center channel dialog level) during the final audio mixing session. The valid range for this parameter is a value from 0 to 31. The peak mixing level is 80 plus the Mixing Level dB SPL, or 80 to 111 dB SPL."
====(end of excerpt)
Using Dolby Lab's Spec. above, I added the MAX value 31 to 75 dB* = 106 dB
From my previously owned Technic's" SA-TX30 Owners Manual:
"When your speakers are set to 75 dB SPL, you can enjoy a much more faithful reproduction of motion picture program material by setting volume control to "REFERENCE". This will recreate the same field of sound as in the film recording studio."
